EL-USB-1 (shown above)
The Lascar EL-USB-1 temperature datalogger 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 a resolution of 0.5°C or 1°F.
To upload the temperature readings the unit plugs directly into any USB port and, with the software for Windows 98, 2000 and XP 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).
Windows software (included with each unit) allows the uploaded temperature data to be listed, 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 temperature control etc.) and food handling and processing etc. Note, any acquired data is retained in flash memory even with a flat battery. The typical accuracy is +/- 1°C (+/- 2°F).
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.
EL-USB-2 (similar to above)
The Lascar EL-USB-2 temperature and relative humidity datalogger is the same 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 an accuracy of +/-3.5% over the 20 to 80% range.
It also has two LEDs (lamps) that indicate status and alarm conditions for both temperature and humidity.
EL-USB-2-LCD (click here for data)
The NEW Lascar EL-USB-2-LCD unit is similar to the EL-USB-2 with temperature and humidity logging capability.
The EL-USB-2-LCD provides an LCD display of current temperature and humidity and last data captured. It also provides a rolling-data capture such that old data is overwritten by new data.
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!
All EL-USB units come with BAT3V6 battery, software on mini CD-ROM and 12 months warranty. The EL-USB-TC comes with 1.5m long K type thermocouple. Click here to see a case study using the EL-USB-TC logger.

The Q1190 or CHY48R Digital Multimeter (DMM) has features like no other. If you compare it to the Fluke 287 for example, it beats it hands-down!
The Fluke 287 costs 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 duration 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. shunt voltage to current) and also external logic outputs for the High and Low alarms. Click here for more information.

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.
The CHY-48R Multilogger with RS232 output (USB output option also available) is a versatile DMM with 4.5 digit back-lit display and all the measurement features of a DMM including voltage, current and resistance plus two temperature measurements (T1 or T2) and temperature difference (T1-T2) - i.e. Dual Input Thermometer - between -50 and +1300°C (-58 to +2000°F), frequency to 10MHz, duty cycle and pulse width to 1KHz, capacitance measurement to 15,000uF (very unusual), 5V logic test, a high and low alarm (with buzzer and logic outputs), date and time-of-day clock and minimum, maximum and average display.
It can store up to 32,000 samples of real time data with an adjustable sample time (from 0.1 seconds to 24 hours) in logging mode with up to 6,500 groups of data (each time you stop and start data recording again it starts a new data group in memory). It also records up to 5,400 events or alarms (it records the start and stop times of high and low alarms) or up to 6,500 manually saved values (records the value, meter setting plus date and time).
The data is stored in internal flash memory (data is not lost with power failure) and may be uploaded to a PC for later analysis. The unit's size is 90x55x200mm (3.5x2.2x7.9") and it weighs 335gm (0.8lbs).
Applications include; test workbench for equipment or component quality control testing (manually performed or integrated into automatic equipment). Machine downtime and fault recording (gives date and time). Chart recording of electrical values, absolute temperature or temperature difference and minimum and maximum event recording and display. Incoming and outgoing goods testing and sorting. Electrical and electronic research, construction and repair work. A truly versatile instrument (just like a one channel datataker) with end-less possibilities!

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!
Similar plots can also be obtained from the EL-USB-1 temperature logger and the EL-USB-2 Temperature and Humidity logger.
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 the Lascar data loggers doesn't have an actual display, 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. Please note that the EL-USB-1 has been upgraded with better battery contacts.
3. All the EL-USB units 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!

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, 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.
