What the detector does and who uses it
The Inficon TEK-Mate 705-202-G1 is a heated diode refrigerant leak detector built for HVAC technicians and automotive specialists. It pinpoints leaks in systems charged with CFC, HCFC, HFC and HFO refrigerants, including 2L flammable types. The handheld unit runs on two D alkaline batteries and ships with a carrying case, sensor and filter for immediate field use.
Sustained field performance
A mechanical pump draws sample air continuously across the heated diode, giving steady response during long inspections rather than a brief sniff test. Two selectable sensitivity levels let the user tune detection down to 0.25 oz/yr for small leaks or open it up for faster surveying. Battery power avoids cord drag and keeps the tool running through a full workday without mains access.
Install, start-up and common pitfalls
Turn the detector on, allow the sensor to warm up, then choose the sensitivity level that matches the job. The most frequent issue is a clogged sensor filter, which kills sensitivity until replaced; keep spares in the case. Battery voltage drops gradually, so swap cells before the low-power indicator appears or the pump will lose flow. Avoid dropping the unit, as the heated diode is fragile and not field-repairable.

Questions about this item
How much power does the heated diode sensor draw from the two D alkaline batteries during all-day use?
The detector runs on two D alkaline batteries; no external power supply is required.
What refrigerants must already be present in the system for the detector to find a leak?
It detects CFC, HCFC, HFC and HFO refrigerants, including 2L flammable types, at sensitivities down to 0.25 oz/yr.
Can the sensor and filter be replaced when they wear out on older equipment?
The kit includes a carrying case, sensor and sensor filter, so replacement parts are available for continued use.
