Testo 515 Ex Gas & Refrigeration Combination Leak Detector

What is the Testo 515 Ex Gas & Refrigeration Leak Detector?

The Testo 515 Ex Gas & Refrigeration Combination Leak Detector (0563 0515) is an ATEX-certified leak detector designed for HVAC engineers, refrigeration technicians and gas maintenance professionals. With interchangeable sensors, it detects refrigerant leaks and flammable gases, including methane, propane, butane and hydrogen (forming gas), making it a versatile instrument for heating, cooling and refrigeration systems.

 

Reliable Gas and Refrigerant Leak Detection

The Testo 515 Ex combines high sensitivity with advanced fan-assisted suction for response and recovery times of less than two seconds. Its refrigeration sensor detects HCFC, HFC, HFO, HCFO, hydrocarbon refrigerants including R290 and blends, with leak sensitivity down to 1 g/year. The flexible gooseneck probe and optical, audible and vibration alarms help technicians locate leaks quickly, while ATEX certification supports use in potentially explosive Zone 2 environments.

 

How does the Testo 515 Ex stand out in everyday use?

The interchangeable sensor system allows engineers to switch between gas and refrigerant detection using one instrument. Its colour display offers numerical readings, bar graphs and trend curves for clear leak analysis, while the rechargeable lithium-ion battery provides up to eight hours of operation. Both sensors are included, offering greater flexibility for engineers working across different applications.
