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. 

EL-WEM+ Measurement Parameters:

  • CO2
  • Temperature
  • Humidity
  • VOC's
  • PM1, PM2.5, and PM10
  • Pressure

The EL-WEM+ provides constant real-time measurement whilst also automatically uploading measurements to the EasyLog Cloud, for easy access to your current and historical data. Download the EasyLog App allowing your complete set of data measurements to be viewed, analysed, and downloaded from any internet-enabled device.  You can even configure a night mode which also mutes the sounder and turns the LEDs on.
