RS-CO2-N01-2-2000P 0-2000ppm Wall-Mounted Carbon Dioxide Sensor - RS485

RS-CO2-N01-2-2000P 0-2000ppm Wall-Mounted Carbon Dioxide Sensor - RS485

The RS-CO2-N01-2-2000P 0-2000ppm Wall-Mounted Carbon Dioxide Sensor (RS485) is a 3-in-1 environmental sensor and transmitter featuring an RS485 Modbus RTU output, designed for the simultaneous monitoring of ambient carbon dioxide concentration, temperature, and relative humidity.

It utilizes NDIR (Non-Dispersive Infrared) sensing technology for CO₂ measurement.

NDIR technology reduces issues related to sensor consumption and chemical aging during long-term measurements compared to electrochemical CO₂ sensors.
