The 420 MCD Multiple Channel Detection controllers are advanced "Early Warning" microprocessor based electronics to monitor a wide range of gases.

SenTech's 420 MCD Controllers are cost effective, self-contained systems offering highly reliable performance with the flexibility to satisfy a wide range of continuous monitoring applications. The 420 MCD features multi-zone detection point capability from a single field-programmable self-contained metal enclosure to power and monitor a variety of 24 Vdc, 4-20mA oxygen, and toxic or combustible gas sensor/transmitters.

SenTech's 420 MCD Controllers utilize sensors with long-term stability, excellent selectivity, and multi-zone detection point capability from a single field-programmable self-contained metal enclosure, The 420 MCD multiple channel architecture is available in two, four, and eight sixteen channels, each channel capable of monitoring specific gases via remote transmitters a unique configuration that allows the 420 MCD to be set up as a Multi-Gas monitor for a wide range of gases along with a unique built-in leak wait period feature that minimizes nuisance false alarms.

Sensor/transmitters are available for a wide range of toxic and combustible gas sensor / transmitters. A partial list follows:

O2,H2S,CO,Cl2,HCN,H2,NO2,HCl,SO2,ETO,

O3,F2,NH3,HF,ClO2,AsH3,PH3,SiH4.
