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.

The EL-SIE-2+ is a high-accuracy model version and measures temperature and relative humidity. Other models that measure temperature only, or temperature, humidity, and pressure, are available.
