WiFi COand Indoor Air Quality Monitor


The EL-WEM+ CO2 and Indoor Air Quality (IAQ) Monitor from EasyLog is the ideal device for ensuring adequate levels of air quality at work and at home.

Measuring and recording CO2 levels, temperature, humidity, VOCs, pressure, PM1, PM2.5 and PM10, the EL-WEM+ continually monitors the IAQ, rating it on five levels from Excellent to Inadequate. If the IAQ falls to the two lowest levels, the device’s status ring light turns to red, a sounder alert is activated and an email and SMS notification can be set up to be sent to your selected contacts notifying you of the change immediately.

Perfect for homes, and workplaces, the EL-WEM+ includes a Do Not Disturb mode, allowing you to set times of the day when the status ring and sounder are turned off.
