2-in-1 Leak Detection for Refrigerants and Flammable Gases

SKU: 0563 0515

The Testo 515 Ex Combination Leak Detector provides fast and precise detection of refrigerant and flammable gas leaks in demanding professional environments. With sensitivity down to 1 g/a and a response and recovery time of less than 2 seconds, it enables technicians to quickly locate even small leaks.

Its flexible and robust gooseneck allows reliable detection in tight or difficult-to-access areas, while selectable colour display modes provide numeric, bar graph, and trend curve views for clear leak analysis. Interchangeable sensors allow the same instrument to detect both refrigerants and flammable gases.

With ATEX certification, the Testo 515 Ex is designed for use in potentially explosive environments where reliable leak detection and appropriate equipment certification are essential.

Key Features

  • 2-in-1 detection of refrigerants and flammable gases
  • High sensitivity with leak detection down to 1 g/a
  • Fast response and recovery time of less than 2 seconds
  • Advanced fan suction for rapid leak detection
  • Flexible and robust 295 mm gooseneck probe
  • Selectable colour display modes with numeric, bar graph, and trend curve views
  • Interchangeable sensors for refrigerant and flammable gas detection
  • Optical, audible, and vibration leakage alarms
  • ATEX certified for potentially explosive environments
  • Long-term sensor stability with replaceable sensors

The Testo 515 Ex combines fast detection with flexible operation for professional leak inspection. Advanced fan suction helps achieve rapid response and recovery, while the selectable display modes make it easier to monitor leak levels and pinpoint the source.

Why It Matters

Gas and refrigerant leaks can create safety, environmental, and operational risks. A combination leak detector provides technicians with a versatile solution for inspecting systems where different gases may be present, including:

  • Air conditioning and refrigeration systems
  • Commercial and industrial refrigeration equipment
  • Gas boilers and heating systems
  • Gas pipes, connections, and appliances
  • Industrial equipment using flammable gases
  • Potentially explosive or hazardous work environments

The Testo 515 Ex allows technicians to switch between refrigerant and flammable gas detection using interchangeable sensors, providing a practical solution for demanding service and maintenance applications.
