Which device is a common refrigerant leak detector?

• A. Soap bubble tester
• B. Halide torch
• C. Electronic refrigerant leak detector
• D. Pressure gauge

Answer: (B)

Detecting refrigerant leaks relies on tools that can sense escaping gas in the air. The most common device used today is an electronic refrigerant leak detector. It senses trace amounts of refrigerant vapor and helps you pinpoint the leak quickly by following stronger readings as you move along joints and fittings. This method is favored for its sensitivity, speed, and safety, and it works with many different refrigerants. Soap bubble testers can reveal a leak by forming bubbles at the leak site, but they’re slower and less reliable for accurately locating leaks on a pressurized system. A halide torch uses a flame test to indicate halogenated refrigerants and is an older method that’s largely been replaced by electronic detectors due to safety and practicality concerns. A pressure gauge measures system pressure and can indicate a problem if a pressure drop occurs, but it does not actively detect or locate leaks.
