CO2 indoor air quality

ESSE-10 CO2 alarm for IAQ, LEED & safety


  • Indoor Air Quality Monitor
  • Automatic Baseline Correction (ABC) CO2 Transmitter
  • Wall-Mount Device with Mains Power
  • Low Maintenance – Saves Money
  • Audible and Visual Alarms

The ESSE-10 CO2 Monitor is ideal for monitoring indoor air quality in offices, workplaces and cafes with soft drink vending machines.

The ESSE-10 CO2 Monitor has inbuilt audible and visual alarms that alert you to poor indoor air quality. When CO2 levels exceed 1400 ppm, the LED lights flash red and an 80 dB alarm will sound. The alarm can be easily turned off with the mute button on the front of the unit.

The default eSense is normally maintenance free thanks to the built-in self-correcting ABC algorithm (Automatic Baseline Correction). This algorithm constantly keeps track of the sensor’s lowest reading over several days and corrects for long-term drift.
