Temperature and humidity data logger with display

Advanced onboard software means there is nothing to install on your PC or Mac – simply connect the logger with a USB cable and use your web browser to configure the device and view, analyse and download your data. It really couldn’t be easier.

The bright and clear display shows current readings and device status at a glance, and the product is supplied with a bracket for secure wall mounting. EL-SIE-2+ uses standard AAA batteries and typical battery life is over 1 year.
