The EasyLog EL-WEM+ indoor air quality (IAQ) and CO2 concentration meter is the ideal device for ensuring adequate air quality in the workplace and home.
By measuring and recording CO2 concentration, temperature, humidity, VOCs, pressure, PM1, PM2.5, and PM10, the EL-WEM+ continuously monitors indoor air quality, rating it on a five-level scale from Excellent to Unsatisfactory. If indoor air quality drops to the two lowest levels, the device's status indicator light turns red, the alarm is activated, and you can set up email and SMS notifications to selected contacts to immediately inform them of the change.
Perfect for home and work, the EL-WEM+ includes a Do Not Disturb mode, allowing you to set times of day to turn off the status indicator light and alarm.
EL-WEM+ provides continuous real-time measurements and automatically uploads measurements to EasyLog Cloud for easy access to your current and historical data. Downloading the EasyLog app allows you to view, analyze, and download all measurement data from any internet-connected device. You can even configure a night mode, which also mutes the alarm sound and turns on the LED lights.
