INFICON Introduces D-TEK® 3 Refrigerant Leak Detector

Refrigerant and CO2 detection in one reliable unit

Syracuse, NY — August 5, 2020:  The new INFICON D-TEK® 3 Refrigerant Leak Detector provides service technicians fast, accurate leak detection that minimizes the cost and environmental impact of escaping refrigerants. D-TEK 3 is built on the proven technology and unparalleled performance of the company’s D-TEK Select Refrigerant Leak Detector that is a market-leader for refrigeration and air conditioning service worldwide.

Recent changes in government regulations, driven by concerns over global warming and ozone depletion, have led to more stringent requirements for refrigerant leak checking of cooling systems. D-TEK 3 can quickly and reliably locate CFCs, HCFCs, HFCs and HFOs, blends (including A2Ls). In addition, with the optional CO2 sensor, this hand-held unit can also detect CO2 leaks making it a cost-effective alternative for service technicians that traditionally must carry two separate instruments to cover this range of gasses. 

D-TEK 3 provides user confidence with a 1 g/year sensitivity which does not degrade over time. Service technicians will especially like the 10-hour battery life and simple field replaceable sensor that minimize downtime and optimize service calls. D-TEK 3 Refrigerant Leak Detector comes with a rugged carrying case and has a two-year replacement warranty.
