Email of the month (2009): 'Dear Peter, Just wanted to say THANKS! so much for getting the EL-USB sensors delivered on time for our study - with everything there and working properly. Particularly, thank you for taking the time to test the equipment and also copy the software on a regular CD for me - as it turned out the new EL-USB-LCD required a newer version of the software - and the manufacturer supplied "mini" CD does not suit the slot drive on my laptop - but your CD did! These USB dataloggers are otherwise very user friendly and their portability is great. All the best.' Trevor, Monash University, Melbourne.

EL-USB-1 (shown above)
The Lascar EasyLog EL-USB-1 temperature datalogger (formally part no. QP6012) is only 100mm long and 26mm in diameter and stores up to 16,382 temperature readings in the range from -35 to 80 degrees C (-31 to 176°F) with an resolution of 0.5°C or 1°F. The typical accuracy is +/- 1°C (+/- 2°F). NOTE, the repeatability is good so a calibration curve could be used for greater accuracy!
To upload the temperature readings the unit plugs directly into any USB port and, with the software for Windows 98, 2000, XP and Vista (32 bit) provided, allows the capture rate (10 seconds or 1, 5, 30 minutes or 1, 6, 12 hour intervals), high and low alarms and the start date and time to be set.
Two LEDs (lamps) on the EL-USB-1 indicate the status and alarm conditions. The high and low alarms may be set to latch so that the alarm conditions are never missed.
The unit then operates for up to one year* (with the 1/2AA 3.6V lithium battery provided) independently of the PC. When the protective cap is fitted, the unit is environmentally protected to the IP67 standard (meaning 'Ingress Protected' against dust and moisture).
The EL-USB-CASE is available with rugged metal alloy design for harsh conditions (waterproof to IP-67/NEMA-4X).
The EasyLog USB Windows software (currently version 5.00) allows the uploaded temperature data to be graphically displayed, printed and exported to reports or to Excel (or other applications) for more detailed analysis and customization of the graph (an Excel macro is provide).
An ideal device for recording temperatures around the home, office or factory - clip it onto any thin flat surface or screw it to a wall etc. Log temperatures inside refrigerators (for health department purposes) or during movement or shipment of goods.
A multitude of applications await this device in engineering, medical, technical and research and scientific areas as well as environmental monitoring (in agriculture, horticulture, building/warehouse/museum/art gallery temperature recording etc.) and food handling and processing etc. Note, any acquired data is retained in flash memory even with a dead battery.
Also see 'Tips on measuring temperature' below. *Depending on sample rate, ambient temperature and use of alarm LEDs.
For low temperatures (down to -200°C) or high temperatures (up to 1300°C) see the new EL-USB-TC thermocouple (J K ot T type) datalogger. This logger is also capable of logging at 1 second intervals!
EL-USB-2 (shown above)
The Lascar EasyLog EL-USB-2 temperature and relative humidity datalogger is similar in size and specifications as the EL-USB-1.
It logs up to 16,382 temperature readings and 16,382 humidity readings (that also means up to 16,382 dew point readings).
The humidity measurement range is 0 to 100% with a resolution of 0.5% and an accuracy of +/-3% over the 20 to 80% range. The typical temperature accuracy is +/- 0.5°C (+/- 1°F).
It also has two LEDs (lamps) that indicate status and alarm conditions for both temperature and humidity.
Click here for a graph of temperature, humidity and dew point using the EasyLog USB software supplied. The graph also shows the high and low alarms!
A more accurate model, the EL-USB-2+, and the EL-USB-2-LCD with LCD display are now available.
For a 'real-time' model that logs direct to the PC from any USB port, see the EL-USB-RT.
Capable of alerting you through emails, a text message on-screen or computer beep of a high or low alarm condition! An Application Programming Interface (API) will also be available soon so you can write your own software! e.g. access the data directly in Excel in 'real-time'.
EL-USB-3 (shown above)
The Lascar EasyLog EL-USB-3 logs up to 32,510 voltage readings between 0 and 30 Volts. The sample interval is 1 second to 12 hours. The internal resolution is 50mV and accuracy is +/- 1%. High and low alarms are provided with LED status indication.
The EL-USB-3 is ideal for monitoring power supplies and process control voltage signals. A 24VDC power supply is commonly used in process control and most ON-OFF or digital signals are 24V. e.g. the unit could be used to monitor the activation of an emergency stop or other control function. Also analogue voltage outputs are common in the 0-10V or 0-5V range and could be logged with the EL-USB-3.
NOTE: higher voltages may be monitored (with caution > 60VDC) simply by using a resistor divider circuit!
See Fort Stanton Cave Study Group (FSCSG) speleologist's casestudy click here.
EL-USB-4 (shown above)
The Lascar EasyLog EL-USB-4 logs up to 32,000 current readings between 0 and 22mA. The sample interval is 1 second to 12 hours. The internal resolution is 0.05mA and accuracy is +/- 1%. High and low alarms are provided with LED status indication.
This unit may be used to record 4-20mA current loop signals in process control.
Teamed with a suitable 4-20mA converter it can be used to monitor resistance (rotary or linear movement), voltages and currents, stain gauges, pressure transducers, load cells, level sensors, distance measurements, RPM, flow etc.
The software provides conversion to the units and range of your choice or you can simply use the standard 0% (4mA) and 100% (20mA) setting and convert within Excel. Note, a disconnected current loop is shown as -25% (0mA) and an overrange current loop is shown as 115% (22.4mA).
The unit connects into a circuit by the terminal connector in the USB cap. The shunt resistance is 110 ohm and is also located in the cap which means that the data logger may be safely removed (to upload data or replace it) without interupting the curent loop!
A simple calculation suggests that the unit is capable of measuring voltages between 0 and 2.5 Volts. i.e. use the EL-USB-4 to measure low voltages with higher resolution than the EL-USB-3!!

The Q1190 or CHY48R (from CHY Firemate Co.) Digital Multimeter (DMM) has features like no other. If you compare it to the Fluke 287 (or 289) for example, it beats it hands-down!
The Fluke 287 costs two to three times the price! The Fluke 287 logs only 10,000 values the Q1190 does 32,000 AND the Q1190 logs up to 5,400 events or alarms.
The Fluke 287 samples only once per second, the Q1190 samples 10 times per second. The Fluke 287 has one thermocouple measurement, the Q1190 provides two (T1 & T2) plus the temperature difference (T1-T2) can be measured and logged.
The Fluke 287 is powered by SIX AA batteries, the Q1190 uses one 9V battery and can be powered from the mains power adapter (no time limit on data logging).
The Q1190 has a simple rotary selection dial that shows ALL functions available, just like a standard DMM. The Q1190 has numerous 'adapter' modes of operation (e.g. voltage to current conversion for shunts or current clamps and 4-20mA current loop measurement as 0..100%) and also external logic outputs for the High and Low alarms. Click here for more information.
To find out more about Digital Multimeters and what they do, go to: www.doctronics.co.uk/meter.htm.
Q1190 (shown above) LOGS UP TO 32,000 ITEMS OF DATA!
SPECIAL NOTE: A meter, such as the Q1190, without auto-ranging is better for data logging. Errors in accuracy and abnormal or 'ghost' readings can occur on meters with auto-ranging!
Also processing the data in Excel or other programs can be more difficult with auto-ranging meters.
In most applications, we recommend the use of Varta alkaline batteries and the Rezap battery doctor.

More information on Q1190:
One customer commented that the Q1190 couldn't record enough data for him to use it over a weekend. I suggested increasing the sample time, but he complained that he could miss the data peak if he did this. I then suggested using the events or alarm monitoring mode where it records the time and date of a high or low alarm condition (and the time and date when it returns to normal). That solved the problem!
NOTE, the high and low alarms can simply be used as two thresholds (with the buzzer turned off).
The graph below shows how simple it is to plot data obtained by the Q1190 meter. The temperature was measured when the T1 thermocouple was plunged into a beaker of ice cold water. The data was uploaded and saved as an Excel file. The file, with 100 data samples, was then loaded into an Excel spreadsheet and graphically presented. p.s. this was done by a 12 year old in a few minutes!
Tips on measuring temperature:
1. Be careful when placing the temperature sensor. Radiant heat will increase the temperature measured. The greatest source of radiant heat is, of course, the sun! Whether using it indoors or outdoors, for greatest accuracy, keep you sensor device out of direct sunlight. Also keep it in a dry environment if possible. Evaporating water cools - therefore the temperature will be lower!
2. As most Lascar data loggers don't have an actual display (except the EL-USB-2-LCD), always test the unit over a short period first (e.g. 24 hours or more) before committing to long term monitoring. Also check that the battery contacts are clean and firm (tip, use DeOxit Gold). Please note that the EL-USB-1 has now been upgraded with better battery contacts!
3. All EL-USB units (except EL-USB-3 and EL-USB-4) can be set to acquire data whilst plugged into a USB port but data recording must be stopped when uploading the data. The status can be uploaded whilst sampling showing the start time & date and the number of samples taken. Note, leaving the device plugged into the USB port causes high drain on the battery and hence some of the battery capacity will be lost!

The NEW Lascar EasyLog EL-USB-2-LCD unit is similar to the EL-USB-2 with temperature and relative humidity logging capability.
The EL-USB-2-LCD provides an LCD display of the last logged temperature and humidity readings and the minimum and maximum values logged.
It also provides a rolling-data capture capability, which can be turned on or off, such that old data is overwritten by new data. This provides an excellent fault finding capability... set it to log at the maximum rate (every 10 seconds) and then, only when necessary, grab the unit and upload the last 45 hours of temperature and humidity readings!
Another important feature provided on this unit is a press-to-start operation. Now you can position the unit before starting the data logging operation (however long it takes).
This unit is ideal for use in indoor applications such as in museums and art galleries and other environments where temperature and humidity records must be kept.

Operating environment: 0 to 40 °C < 70% relative humidity (R.H.). Storage: -20 to 60 °C 0-80% R.H. with battery removed. Safety: EN61010-1 (CAT II 600V).
Range: Volts: 200mV, 2V, 20V, 200V, 600V AC/DC, Amps: 200uA, 2mA, 20mA, 200mA, 10A AC/DC (fused 0.5A and 10A), Resistance: 200, 2K, 20K, 200K, 2M, 20M ohm, Continuity: 30 ohm threshold, Diode test: 2000.0mV at 0.4mA, Frequency: 2Hz - 10MHz, Duty Cycle: 10% - 90%(0.5Hz to 1KHz), Pulse Width: 20ms - 2000ms (1Hz to 1KHz), Logic Test: <0.8V low >2.8V high to 20MHz, Capacitance Cx: 2000.0pF - 20.000uF, F: 200.0uF - 15,000uF, Temperature: -50.0 to 1300.0 °C.
Accuracy of meter at room temperature: DC voltage 0.05% of reading AC voltage 0.75% DC current 0.5% AC current 0.75% Resistance 0.2% Diode Test 3% Frequency 0.1% Duty Cycle 2% Capacitance 2% < 20uF, 5% > 20uF Temperature 0.1% + 1°C (a calibration feature can reduce this error). Input impedance (Volts all ranges): 10M ohm. Resolution: 10uV, 0.01uA or 10nA, 10m ohm, 0.0001Hz, 0.1°C/°F.
Adapter settings are available to measure current (1mV = 1A, 0.1A or 0.01A) using a resistive shunt or using an AC clampmeter such as the QM1565 (300A 600V AC max.) or QM1566 (1000A 1000V AC max.) These record and display in Amps rather than in milliVolts. You can also measure temperature where 1mV = 1°C or 1°F (e.g. standard modules are used for thermocouple to analog conversion e.g. Fluke 80TK and Omega TAC80B) and 4-20mA current loop which is displayed as 0 to 100%.
A mini DIN socket provides open collector outputs of alarm high and alarm low. This can be multiplexed with other meters. RS232 output provides optical isolation with 9 pin D type female plug.
The Windows software provides the ability to upload saved data from the meter and store it to file in text or Excel format. The software also allows monitoring the currently displayed meter reading in digital, analogue, bar graph and chart formats.
The software also allows the ability to take readings from the meter at any time (records the value, meter setting and time). High and low alarm values may also be set on the computer and values read may be sorted or binned in up to 10 different value ranges (bins A,B,C..J).
A driver for National Instruments LabView is provided which (I assume) means it can be used with this software. The documentation and software could be improved but the DMM works remarkably well and is easy to use.
Other applications for this meter include logging events manually in the factory, home, office, sports field or on the road. e.g. you could use a simple resistance box to select from one of a number of options and then press the 'save' button when that event occurs. The meter will record the resistance (option selected) and the time and date that it occurred.
You could use this meter with automatic (or operator controlled) test equipment with the mini DIN outputs providing a PASS or FAIL. Use it to automatically record temperatures or temperature differences (two thermocouples are provided with a T1 minus T2 measurement). One application for the temperature difference is to measure the operation of a car or truck radiator with one probe on the inlet and another on the outlet.
