Handheld Gas Detection
D-Tek Select
Refrigerant Leak Detector
As the first accurate, reliable, highly sensitive, cordless refrigerant leak detector, the original D-TEK revolutionised the field. Now we have built on that technology leadership to create the D-TEK Select.

This next-generation of refrigerant leak detector uses an innovative infrared absorption sensing cell that is extremely sensitive to all HFC and HCFC refrigerants and even the new generation HFO's such as R1234YF.
D-TEK Select maintains that sensitivity over time for consistent, accurate and reliable performance, even with the newer refrigerant blends. Best of all, the sensing cell lasts for approximately 1000 hours - almost 10 times longer than the original D-TEK sensor - to lower your cost of ownership and improve job site productivity.
Additional enhancements include a charging status indicator, sensor failure indication, and NiMH (nickel metal hydride) batteries. All in an easy-to-use unit with the quality and durability you've come to expect from INFICON.
Technical Overview
At the heart of the D-TEK Select Refrigerant Leak Detector is an infrared absorption filtometer. It consists of a sampling cell with an infrared source (or emitter) at one end, an infrared energy detector at the other end, and an optical filter in between them.
Like the visible light we see, infrared energy is part of the electromagnetic energy spectrum. Most materials absorb specific and known wavelengths of infrared energy. The particular wavelengths of energy absorbed by a material are known as its absorption spectra. Refrigerants have their own unique absorption spectrum.
The infrared source (emitter) creates a high-intensity stream of energy incorporating all wavelengths in the infrared spectrum.
The filtered infrared energy passes through the sampling cell, striking the infrared detector. D-Tek Select is ready to sense any HCFC, HFC, HFO refrigerant.
Filtered infrared energy is absorbed by the refrigerant present in the sampling cell, causing D-Tek Select to alarm.

At a Glance
- 3 grams/year sensitivity.
- Equally sensitive to all refrigerants, including R-22, R-134a, R-404a, R-410a, R-507 and all CFCs, HCFCsand HFCs.
- 800-hour infrared cell life for low cost of ownership.
- Infrared cell does not weaken over time, so response remains consistent and accurate.
- Infrared cell cannot be overloaded or "poisoned" by exposure to large amounts of refrigerant.
- Selective to refrigerants only; will not react to smoke, humidity, airflow or temperature changes.
- High-efficiency air sampling pump provides quick response and quick clearing ("zeroing").
- On-board diagnostics indicate charging status and warn of low battery or infrared cell failure.
- NiMH power stick is environmentally friendly, will not corrode, and provides greater charging capacity.
