Temperature Data Logger with LCD screen

This standalone data logger measures and stores more than 16,000 temperature readings over a -35 to +80°C range with a resolution of 0.5°C.
The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free EasyLog software.
Data can then be graphed, printed and exported to other applications for detailed analysis.
The high contrast LCD can show a variety of temperature information.
At the touch of a button, the user can cycle between the current, maximum and minimum stored values for temperature.
The data logger is supplied with a lithium metal battery which gives two year’s logging life.
The logger is protected against ingress from water and dust to IP67 standard when the cap is fitted.

Temperature and Relative Humidity USB Data Logger available on request.

Lascar’s EasyLog control software is available as a free download from www.easylogusb.com.
Easy to install and use, the control software is compatible with 32-bit and 64-bit versions of Windows 7, 8 and 10.
The software is used to set up the logger, download, graph and annotate data or export in Excel, PDF and jpeg formats.

The software allows the following parameters to be configured:
• Logger name
• Measurement parameter (°C or °F)
• Logging rate (user selectable between 10 seconds and 12 hours)
• High and low alarms
• Immediate and delayed logging start

The EL-USB-1-LCD features a high contrast LCD which shows logged temperature values using seven segment numbers, along with annunciators.
The LCD can also show information regarding the logging status.
The LCD shows three different recorded readings, which can be cycled through using the built-in push button.
The most recent logged temperature, maximum logged temperature and minimum logged temperature can be displayed.


EL-USB-1-LCD features two LEDs:

▪ The first LED flashes red to indicate that the EL-USB-1-LCD is in an alarm condition. It will flash when the logged temperature has exceeded a Low or High alarm level.
▪ The second LED flashes green to indicate that the EL-USB-1-LCD is not in an alarm condition.

Using EasyLog software it is possible to set the alarm to remain active even if the reading has returned to normal, in which case the alarm LED will continue to flash red. This ‘Hold’ feature in the software ensures the user is notified that at some point an alarm level has been exceeded, without needing to download the data.

Hold is enabled by default, and can be turned off via the control software. The red LED will then only flash whilst the logger is in an alarm condition. When the temperature returns to normal, the green LED will flash.

We recommend that you replace the battery annually, or prior to logging critical data.
Only use 3.6V ½AA lithium metal batteries.
The data logger does not lose its stored readings when the battery is discharged or replaced; however, the data logging process will stop and will not resume until the battery is replaced and the logger restarted by EasyLog software or an EL-DataPad.
Before replacing the battery, remove the data logger from the PC. Please note that leaving the data logger plugged into the USB port for extended periods will cause some of the battery capacity to be lost.


If left unused for extended periods of time lithium metal batteries, including those used in the EasyLog range of data loggers, naturally form a non-conductive internal layer preventing them from self-discharge and effectively increasing their shelf life.
When first installed in the data logger, this may cause a momentary drop in the battery voltage (the Transient Minimum Voltage) as the internal layer is broken down, resulting in the data logger resetting.
Inserting the batteries in the data logger and leaving it connected to a PC for about 30 seconds will remove this layer.
After this, remove and re-install the batteries to reset the data logger. Overall battery life will not be affected.
