CD-30M/30I are designed for air conditioning system being installed on air conditioning duct system. With built-in transmitter, CD-30M/30I can detect CO2 gas density using NDIR (Non Dispersive Infrared) and convert the measured density signal into linear current or voltage signal to be transmitted to external monitoring unit or controlling unit such as PLC or DDC.

[ Features ] 
 
ㆍ Non Dispersive Infrared(NDIR) CO2 sensor 
    highest detection accuracy and the longest sensor life time with the least affection from other gases. 
ㆍ Built-in transmitter 
    Built-in transmitter transforms the sensor signal into stable standard current output signal (4-20mA) to be transmitted to external controlling equipments such as PLC or DDC. 
ㆍ Robust metal housing 
    RS-485 enables stables stable and long distance (maximum 1.2km) signal communication.
