SenTech manufactures “Early Warning” single and multipoint INFARED based refrigerant monitors, featuring the ability to offer one monitor programmable for multiple refrigerants in the same location.

SenTech's Infrared monitors are cost effective active air-draw sampling systems designed specifically for refrigerants. SenTech monitors offer one, four, eight and sixteen zone detection point capabilities from a single field programmable self-contained metal enclosure.

Each zone is capable of monitoring and responding to any one of 20 refrigerants from a standard library via keypad entry.  The monitors are expandable, offering flexibility to change configuration or applications at a later date. SenTech’s monitors comply with ASHRAE-Std 15.
