CO2 Bus Sensors
Interior sensors CO2+T+RH - types RK-CHM...
Measuring T+RH+CO2
- RK-CHM-L..........sensor with indicator LED
- RK-CHM-L..........sensor without indicator LED
- long-term stability of CO2 measurement - NDIR sensor
- communication over RS485 line, protocol ModBus RTU
- configuration via the USB port
- can also be used in systems with 24VAC power supply (with additional MN24 converter)
