Refrigerant leak detection is a technology that is always improving. Sensitivities are constantly improving as well as the life expectancy of sensors. Inficon remains a leader in this regard as their new Inficon D-TEK Select 712-202-G1 Refrigerant Leak Detector is outstanding. The sensitivity on this unit is very low at 0.10 oz/yr(3 gm/yr). This allows you to find just about any leak a system might have. The unit uses an infrared sensor cell with a life expectancy of roughly 800hrs and is backed by a 2 year warranty from Inficon. Since this is an IR Cell you do not have to worry about over exposure ruining the sensor, which is a huge bonus over the old heated sensor style detectors. The Inficon D-TEK Select 712-202-G1 Refrigerant Leak Detector is simple to use and is ready to detect right out of the box. There is a selectable sensitivity as well so you can close in on your leak once the unit picks it up the “scent”. If you are in the market for a new refrigerant leak detector, i would definitely give these a look and get it while they are on sale.

Cheers and Happy Testing,
