CH2O transmitter including digital measurement value processing and temperature compensation for the continuous monitoring of the ambient air to detect formaldehyde concentrations. Integrated in the transmitter there is a comfortable calibration routine with selective access release. The ADT-53 possesses a standard analog output (0) 4- 20 mA or (0) 2– 10 V DC, and an RS-485 interface. 2 relays with adjustable switching thresholds are available as an option.
For the detection of formaldehyde within a wide range of industrial and commercial applications. Due to the standard output signal and the RS-485 interface the CH2O transmitter is compatible to the PolyGard Gas Controller series MGC and DGC by MSR-E as well as to any other electronic control or automation system.
