Calibration procedure 

 

The calibration procedure is performed periodically and involves introducing a known gas concentration at the sensor 
inlet, using the calibration kit. 
The need to perform calibration is signalled by a specific variable on the supervisor. Each type of device has a different 
calibration interval, as described in the technical specifications table. After a few years of operation, the sensor needs to 
be replaced, as described in the following chapters, as the calibration is no longer sufficient to guarantee reliability of 
the measurement performed. 
 
The CO2 detectors do not require periodic calibration, but simply replacement of the sensor after approximately 7 years. 
Calibration can be performed every 12 months if wanting to guarantee greater accuracy of the measurement or if needing 
to issue a new calibration certificate. Below is a description of how to calibrate via the controller or via the app.

Calibration kit  

The calibration kit is used to perform periodic calibration required for maintenance of the device. The gas cylinder and 
pressure adapter to perform the calibration need to be procured separately. 
 

 

 
 
 
 
Calibration kit with adapter, humidifier 

 

 
 
 
Use the calibration adapter supplied 

 

 

 
 

Wet 

the filter core with tap water 

 
 
 

 

 
 
 
Put the core back in place and close the filter. Note the direction of air flow (towards the 
sensor). 
Open the regulator on the gas cylinder and let the gas flow for approximately one minute 
without the calibration adapter connected to the sensor, then close the regulator.
