Top 10 Refrigerant Leak Detectors

There are several types of refrigerant leak detectors on the market. Some use corona discharge to detect leaks, while others use heated diodes. Some are a bit bulky but work well for professional HVAC technicians.

Elitech is our pick for the best refrigerant leak detector because of its sensitivity, versatility, and warranty. It also has a great sensor life rating and is more affordable than other options.

  1. Fieldpiece DR58

The DR58 uses both heated diode and infrared technology to quickly find leaks with sensitivity that far exceeds international standards. The large Li-ion battery provides 18 hours of operation and is easy to recharge. The meter will automatically recalibrate every three seconds, or you can choose to manually calibrate it as needed.

Heated diode detectors work by pulling an air sample through the wand and using the internal sensor to heat it. This heat causes the fluorine and chlorine gases in the sample to break down and release positive ions that the DR58 detects, alerting you to a leak. This testing procedure has a little bit of an art to it, and you need to keep the wand moving in a smooth motion. This enables the DR58 to find leaks down to 0.03oz/yr.

  1. Wale&Morn WJL-6000pro

The Wale&Morn WJL-6000pro is a great choice for HVAC technicians and DIY enthusiasts who need to detect leaks in their air conditioning or refrigeration systems. It has advanced sensors that can detect halogen gas leaks in R22, R410A, R134A, R290, R600A, R1234yf, and CFCs, HCFCs, HFOs, and HC. It also has a bright indicator light to help you locate the source of the leak.

This detector has an automatic circuit that tracks the changing levels of halogen gas to avoid false alarms. It is also adjustable and can be set in 7 different sensitivity levels to suit different working conditions.
