EL-SIE-2+

High Accuracy Temperature and Humidity 

USB Data Logger, EasyLog Cloud Compatible

Monitor the environment you live and work in with the EasyLog EL-SIE-2+. Configuration is simple, with no software to install 

on your PC or Mac – just connect the logger with a USB cable, and use your standard web browser to configure the device for 

logging. You don’t even need internet access to set up and use the EL-SIE-2+, it really couldn’t be easier.

The logging interval can be set between 10 seconds and 24 hours, with immediate, delayed, triggered or push-to-start logging. 

Alarms are fully user configurable, with functionality including cumulative alarms, pre-alarms, a delay before alarm triggering, 

and an alarm hold option, which continues showing the alarm condition even if the reading returns to an acceptable level.

The display shows current, maximum and minimum readings, and three coloured LEDs indicate device status at a glance.

Once logging is complete, re-connect to your computer and use your browser to view, analyse and save your data. You can also 

choose to upload your data to an Easy Log Cloud account, making the data accessible online for powerful graphing, analysis and 

report generation.  

Typical battery life is over 1 year using standard AAA alkaline batteries, and a wall mounting bracket is supplied with the device.
