HS-2 Portable CO2 Meter
The HS-2 is ideal to measure the CO2 value, temperature and humidity in an area. The TechGrow HS-2 Portable CO2 Meter uses NDIR (Non-Dispersive Infra Red) technology to ensure reliable measurements, similar to the CO2 sensor that TechGrow uses for years for all monitoring- and controlling instruments.
The HS-2 features a clear audible alarm that warns when the CO2 value exceeds the set alarm value. Also, the HS-2 features a calibration function to calibrate the CO2 sensor against outdoor air.
