Indoor Air Quality


Maintaining good indoor air quality is important for both your students' and teachers' comfort and health. Inadequate air quality has been directly linked to a number of short- and long-term health issues. With the average person spending 87% of their time indoors, whether this be at work, at school, or at home, it is important to understand what contributes to good indoor air quality, how to identify low air quality and how we can improve it if necessary.

Automatic Monitoring

EL-WEM continuously observes Indoor Air Quality, monitoring temperature, humidity, particulate matter, VOC’s and pressure to ensure air quality is always excellent.

Advanced Alerting

If the air quality becomes poor, an alert is automatically sent to selected users to warn them of the change.

EasyLog Cloud-Connected

Thanks to the device’s Cloud-connectivity, all readings are automatically uploaded to the EasyLog Cloud. 

Five Measurement Parameters

EL-WEM monitors five key contributing parameters to Indoor Air Quality:

  • Temperature (-20 to +60°C)
  • Humidity (0 to 95%RH)
  • Particulate Matter (PM2.5, PM10)
  • Volatile Organic Compounds
  • Pressure (300 to 1100mbar)

Indoor Air Quality Monitoring Products

EL-WiFi-TH Application



The Wi-Fi-connected EL-WiFi-TH remotely monitors temperature and humidity via an internal ambient sensor. Live data is displayed on the device's screen, whilst historical data is stored on the EasyLog Cloud, accessible from anywhere, 24.7.

EL-WEM application



The EL-WEM offers a fully automated, cloud-connected indoor air quality monitoring solution. Indoor air quality is automatically calculated and ranked from inadequate to excellent by monitoring temperature, humidity, particulate matter, VOCs and pressure.

EL-IOT-CO2 Applications



The EL-IOT-CO2 measures ambient temperature and humidity, as well as CO2, a key indicator of adequate ventilation. Live data is displayed on the device’s high-contrast LCD screen, whilst historical data is stored on the EasyLog Cloud.
