SenTech Product Overview

SenTech's Infrared Monitors are advanced multi-point refrigerant detection systems designed for highly reliable performance with the flexibility to satisfy a wide range of continuous monitoring applications offering a choice of 1, 4, 8, or 16 zone detection point capability from a single field-programmable self-contained metal enclosure. The monitors utilize NDIR (Non-dispersive infrared) and pyro-electric (absorptive sensing) technology and each zone (detection location) is capable of monitoring and responding to any one of 22 refrigerants from a standard library via keypad entry. The monitors are also expandable, offering users the flexibility to change configurations or applications at a later date.
