Fieldpiece DR82 Infrared Refrigerant Leak Detector — Ultra-Sensitive, Backlit LCD, 17" Probe

The Fieldpiece DR82 is an ultra-sensitive infrared refrigerant leak detector that locates micro leaks down to under 0.03 oz/year with a long-life sensor and easy-to-read backlit display.

Designed for HVACR technicians who need fast, accurate leak locating in equipment and tight spaces, the DR82 combines infrared sensing with a flexible probe, visual and audible indications, and durable construction. It works across the refrigerant families used in modern systems and is built for field conditions with water- and oil-resistant protection and a battery designed to last through long service days.

How quickly will this tool find tiny refrigerant leaks?

The DR82 locates ultra-small leaks rapidly thanks to its infrared detection technology, which is far more sensitive than traditional soap-bubble methods. You’ll get immediate visual and audible feedback so you can zero in on the source instead of guessing.

• Detects leaks smaller than 0.03 oz/year — about 20× more sensitive than bubble tests
• Backlit LCD displays leak intensity and size for instant assessment
• LED tip illumination and audible beeps help pinpoint exact leak points

Which refrigerants and environments is the DR82 appropriate for?

The detector is compatible with the broad range of refrigerants used in HVACR systems, including legacy and newer blend chemistries. Its IP54-rated sensor and replaceable filter tips are engineered to resist common contaminants like moisture and oil in service environments, extending reliable operation.

• Works with CFCs, HCFCs, HFCs, HFOs and their blends
• IP54-rated sensor design protects against moisture and oils in the field
• Replaceable filter tips help maintain performance in dirty or oily conditions

What features help technicians inspect tight or crowded HVAC systems?

The DR82 comes with a 17-inch flexible probe to reach deep into coils, valve bodies, and cramped equipment bays while keeping the main unit accessible. Ergonomic, lightweight construction and a clear backlit display make it simple to operate in dimly lit service spaces.

• 17-inch flexible probe reaches inaccessible areas and coil bundles
• Lightweight housing reduces hand fatigue during extended inspections
• Large backlit LCD and LED tip for visibility in low-light conditions

How durable is the DR82 for regular field use and what about battery life?

Built for the demands of service work, the DR82’s sensing module is rated to withstand moisture and oil exposure, and the sensor is engineered for long service life. A rechargeable USB-C battery delivers full workday runtime on a charge, and filter tips are replaceable to prolong useful life.

• Sensor rated IP54 for resistance against moisture and oil
• Estimated sensor longevity up to 10 years under normal use
• USB-C rechargeable battery offers 10+ hours of runtime per charge

Who this is for: The Fieldpiece DR82 is aimed at HVACR technicians, service contractors, and facilities maintenance teams who require a sensitive, reliable leak detector for routine diagnostics, warranty inspections, and retrofit work. It’s especially useful when you need to find minute refrigerant escapes in tight equipment spaces, validate repairs, or comply with leak-detection protocols without relying on slow or less-sensitive methods.
