CO2 Sensor
NDIR infrared CO2 sensor for barn air quality. 400~5000ppm range with RS485 output and minimal long-term drift.
CO2 Sensor
Our wall-mounted CO2 sensor uses advanced NDIR infrared detection to precisely measure carbon dioxide concentration, avoiding the lifetime limits and drift of traditional electrochemical sensors. It communicates over RS485 with the industrial-standard Modbus-RTU protocol, connecting directly to PLCs and controllers. The IP65 housing is rain-resistant with a breathable membrane that keeps measurements accurate, and power inputs feature over-current, over-voltage, and reverse-polarity protection. Wall-mount and duct-mount installation options are available.
