<< | < | AX-GS-CM-NO2-M - Nitrogen Dioxide and Carbon Monoxide Transmitter, MODBUS RTU
|
| |
|
|
The AX-GS-CM-NO2-M is an ideal solution for detecting harmful emissions in parking garages, loading docks, warehouses etc. It offers detection of carbon monoxide and nitrogen dioxide gases in the same enclosure . Sensor readings are transmitted over RS-485 Modbus RTU protocol. By monitoring the levels of CO and NO2 in the air, the ventilation system can be adjusted to ensure that the air quality is within safe limits. |
