Stop wasting expensive refrigerants and hours troubleshooting. The Fotismex Refrigerant Leak Detector features professional 1PPM sensitivity and a 9.44-inch flexible probe to locate hidden leaks in tight, complex systems with ultimate HVAC precision.




Catch microscopic refrigerant escapes that standard detectors miss. By tracking down the smallest pinhole leaks early, you save clients valuable refrigerant, avoid complete system failures, and bypass costly callouts.
Manoeuvre effortlessly into tight spaces, behind heavy compressors, and inside complex air handling systems. The flexible probe contours easily around pipework to scan hard-to-reach joints without system disassembly.


One diagnostic tool for all halogenated refrigerants. From R12, R22, and R134a to R404a, R417A, and standard CFC, HCFC, and HFC blends, this detector works perfectly across domestic, automotive, and commercial systems.



"The Fotismex Leak Detector offers an exceptional balance of high sensitivity and professional handling. Its progressive audio-visual feedback makes it incredibly fast to isolate microscopic leaks in residential and commercial coils alike."
– Marcus Thorne, Research Specialist


Tracks down minuscule refrigerant leaks that competitors miss. High-precision resolution avoids unnecessary component replacements.

Holds its position perfectly when bent, allowing you to easily manoeuvre around tight engine bays, HVAC coils, and narrow conduit pipes.

Fully compatible with all CFCs, HCFCs, HFCs, and blends. One advanced tool covers everything from domestic AC to commercial cooling systems.


Features graduated audio-visual cues that increase in frequency and bar level as you draw near the leak source, making tracking incredibly intuitive.

Engineered for prolonged field use. The comfortable, non-slip design reduces hand fatigue during comprehensive diagnostics.

Minimises downtime with a rapid warmup and automatic calibration, letting you identify system leaks almost immediately after arrival.









Our technical support team is always ready to assist. Whether you need calibration advice, guidance on checking complex multi-refrigerant setups, or details on preserving probe longevity, we've got you covered.

I was looking for a leak in a commercial system for hours. Hooked up the Fotismex and found the microscopic leak behind a valve within minutes. The 1PPM sensitivity is absolutely outstanding.

Extremely robust casing. The colour LCD screen and progressive beep frequency are spot-on. It's much easier to trace complex lines now. Essential kit for any serious HVAC engineer.

The 9.44" flexible probe is brilliant. Standard rigid detectors couldn't get back behind the coils, but this bends and holds its position effortlessly. Saved me tons of time disassembling ductwork.
