NDIR CO2 Sensor SRH-40

NDIR CO2 Sensor SRH-40SRH-40

SRH-40 sensor is based on the two beam non-dispersive Infrared (NDIR) technology to detect CO2 concentration range  0-40%. SRH-40 NDIR CO2 sensor  is cost-effective and high performance, ideally suited to be applied for grain storage, silobag monitoring. SRH-40 CO2 sensor can also be used for intelligent agriculture, industrial safety, environmental monitoring, gas drainage pipes monitoring and other situations.
