CHESTER Clime IAQ
Monitor indoor air quality continuously and document ventilation performance: CO2, temperature, humidity, pressure, and light in one device.
Product overview
Environmental measurements
Monitoring of temperature, humidity, CO2 concentration, and light intensity
Buzzer and LED button
Pressing the LED button sounds the buzzer and sends data immediately
Configurable alarms
Set an alarm for a specific temperature or CO2 level
Reliable power supply
Powered by an external power supply from 6 to 28 VDC
Backup battery inside
If external power fails, the backup Li-pol battery keeps the device running for up to 1 year
Use cases
Office & workplace health
Ventilate by measurement, not by guesswork. Continuous CO2 data shows when meeting rooms and open-plan offices need fresh air, so facility teams can match ventilation to actual occupancy.
Schools & public buildings
Document indoor air quality without manual checks. Continuous air quality records for schools, hospitals, and public spaces that you can export for inspections and audits.
Construction & building commissioning
Prove your HVAC delivers what was specified. Objective air quality data during handover and post-occupancy validates system performance and resolves disputes.
Warehouse & storage facilities
Protect sensitive inventory and keep workers safe. Continuous monitoring of temperature, humidity, and air quality in storage areas helps prevent damage and documents conditions for compliance records.
