In 1987, SenTech Corporation became the first company to commercially develop, manufacture, and introduce to the HVAC & R industry a "continuous" refrigerant gas monitoring system that provides an "Early-Warning" alarm of the presence of ozone-depleting chlorofluorocarbon (CFC) gas leaks. 

A RECOGNIZED LEADER IN SENSOR TECHNOLOGY FOR EARLY-WARNING REFRIGERANT GAS LEAK DETECTION. PROVIDING ACCURACY, RELIABILITY AND CUSTOMER PEACE OF MIND. SUPPLYING QUALITY PRODUCTS AND SERVICES.


SenTech's IR-SNIF and SSG Monitoring Systems feature "advanced" Infrared-based active air sampling technology which offers the broadest choice and the most reliable refrigerant gas and fire suppression system lead leak detection equipment available in the industry.

SenTech's Environmental Monitors are distributed via a nation-wide network of design-build engineers, contractors, wholesalers, and authorized distributors

IR-SNIF Refrigerant Monitors are capable of sensing the full range of halogen gases and agents, including CFCs, HCFCs, HFCs and HFOs in fluids as well as ambient air. Applications for the HVAC & R industry are commercial, industrial, and retail such as supermarkets, cold storage warehouses, chemical plants, industrial process, cooling facilities, office buildings, shopping malls, institutional buildings, and original manufacturers of refrigeration and cooling equipment

SSG Monitoring Systems offer low cost effective solutions for the prevention of accidental discharges of Halon and FM200 fire suppression systems. Fire suppression system discharges occur more frequently by accident than by fire causing unacceptable downtime and business interruption. SenTech's SSG Monitoring System was specifically designed to provide "Early Warning" alarms to prevent refrigerant and agent leakage from going undetected. While the SSG Monitoring System is economical enough to be used for any operation, it is specifically designed for use in critical environments:

Corporate Data Centers
Telecommunication Switching Facilities
Process Control Rooms
Industrial Robotic Systems
Clean Room Applications
