Inficon Refrigerant Leak Detector TEK‑Mate Model 705-202-G1 — Heated Diode Sensor, 0.25 oz/yr Sensitivity

The Inficon TEK-Mate 705-202-G1 is a handheld refrigerant leak detector that locates CFC, HCFC, HFC and HFO leaks with 0.25 oz./year (7 g/year) sensitivity using a heated diode sensor.

The TEK-Mate from Inficon is built to give HVAC/R technicians a dependable, easy-to-use tool for routine leak searches and service calls. It balances accuracy, affordability, and ruggedness: an industry-proven heated-diode sensing element, automatic background zeroing, and a portability package that includes a durable carrying case and two D-cell power. The detector is A2L certified and designed to ignore false signals from soap solutions while offering a user-friendly interface you can trust in the field.

How accurate is the TEK-Mate at finding small refrigerant leaks?

The detector is tuned for high sensitivity and can spot leaks as small as 0.25 ounces per year (about 7 grams annually). Its heated diode sensor delivers repeatable responses to a wide range of refrigerants, helping you identify faint emissions that might be missed by less sensitive tools.

• Detection sensitivity: 0.25 oz./year (7 g/year)
• Senses CFCs, HCFCs, HFCs and modern HFO blends
• Heated diode sensor gives consistent results across refrigerant types
• Automatic background adjustment reduces false positives

Will the TEK-Mate work with the newest low‑GWP refrigerants and A2L blends?

Yes — the Inficon TEK-Mate is compatible with the broad refrigerant families used in current HVAC/R systems, including low‑GWP and A2L refrigerants. Its sensor chemistry and calibration approach ensure responsiveness to modern blends without sacrificing sensitivity.

• Detects all CFCs, HCFCs, HFCs and HFOs
• A2L certified for flammable-low toxicity refrigerants
• Field-proven performance across legacy and new refrigerant types
• No calibration needed for most routine leak checks thanks to auto-zeroing

How easy is it to operate and maintain during a service call?

The TEK-Mate was designed for straightforward, single‑technician use: power it with two common D-cell alkaline batteries and begin scanning after the automated background zeroing completes. The heated diode sensor offers a useful 100‑hour expected life, and the unit tolerates common onsite utilities like soap solutions without spurious alarms.

• Runs on two D-cell alkaline batteries (widely available)
• Automatic background adjustment simplifies startup
• Sensor life approximately 100 hours; replaceable heated diode element
• Includes rugged carrying case for transport and storage

What support and origin information is available for technicians?

Inficon manufactures the TEK-Mate in the United States and provides US-based technical support via email and phone. That local support structure helps with troubleshooting, spare parts, and sensor replacement guidance when you need it.

• Made in the United States for consistent quality control
• US technician support available by phone and email
• Includes rugged carrying case to protect the unit on job sites
• Simple operation minimizes training time for new users

Who is this for: The Inficon TEK-Mate 705-202-G1 is aimed at HVAC/R technicians, service contractors, facilities maintenance teams, and refrigeration specialists who need an economical yet reliable leak detector for everyday inspections and repairs. It suits those who require broad refrigerant compatibility (including A2L blends), straightforward operation on the job, and a tool backed by US-based support and durable packaging.
