Heated Diode Sensor Refrigerant Leak Detector

Elitech heated diode leak detectors have the best cost-performance in their class, featuring high accuracy, versatility, and quick response. The built-in air-sampling pump makes detection very efficient, quick, and reliable. It can detect the most common refrigerants, including CEC, HCFC, HFC, HC, PFC, and HFO-1234.

The heated diode heats the refrigerant to break down the molecules. When the molecule is destroyed, positively charged chlorine or fluorine ions appear. Heated diodes detect these ions and emit sound, visual, or both alerts. This means that a heated diode detector can smell almost any refrigerant used today. Why is that? Most refrigerants contain chlorine or fluorine.
