1 AIRSENS COV model: room measurement probe

Description:

The VOC sensor comprises a semiconductor heated by a heating resistor. Oxidation of gases and vapors occurs and electrical resistance varies depending on the amount of molecules of organic compounds in contact. The spectrum of molecules to which this element is sensitive is very wide: cosmetics, hygiene products, household products, glues, adhesives, solvents, tobacco ...
2 possible modes of use (selection by switches):
- In servo mode using the 0-10V output of the probe: ventilation flow rate proportional to the air quality.
- In all or little mode using the relay output: minimum ventilation flow rate below the threshold adjustable by potentiometer (factory value 1200 ppm) and maximum above this threshold.
Visualization of air quality by LED:
- 3 colors green / orange / red in servo mode.
- 2 colors green / red in all or little mode.
Automatic calibration.
Communicating Modbus RTU RS485.
Tested in our laboratory on several types of pollutants: household product, hygiene product, solvent, glue, incense, tobacco.
