How Does A Heated Diode Refrigerant Leak Detector Work?
Aug 11, 2020 · When the molecule is destroyed, positively charged chlorine or fluorine ions appear. Heated diodes detect these ions and emit sound, visual or two alerts. This means that a heated diode detector can smell almost any refrigerant used today. Why is that? Most refrigerants contain chlorine or fluorine.

Choosing, Selecting, and Utilizing a Refrigerant Leak Detector
Apr 27, 2023 · Heated Diode — Air is pulled over a heated diode. Halogenated gases are broken down by the heater, resulting in a change in current flow through the diode. The change in current through the diode triggers an alarm.
Fieldpiece Refrigerant Leak Detectors - TruTech Tools
5 days ago · Heated Diode leak detectors trigger on an absolute concentration of refrigerant. Simply put, as you move closer to the leak, the audible and visual indication increase in frequency because more refrigerant is passing the sensor.
