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

Built for HVAC technicians who need repeatable, fast leak detection, the DR82 combines an infrared sensor with a large backlit LCD and a flexible probe to locate hard-to-see leaks. Its sensitivity outperforms traditional bubble tests, and its rugged, IP54-rated sensor and long USB-C battery life make it a reliable tool on busy job sites.

How accurate is the DR82 at finding small refrigerant leaks?

The DR82 uses an advanced infrared sensing element that detects leaks down to less than 0.03 oz/year, making it roughly twenty times more sensitive than visual bubble checks. That increased sensitivity helps catch slow or intermittent leaks before they become major problems.

• Infrared detection sensitivity: <0.03 oz/year
• Detects micro leaks missed by soap/bubble tests
• Backlit LCD quantifies leak intensity for faster diagnostics

Which refrigerants and environments will this detector work with?

The DR82 is compatible with a wide range of refrigerants used in HVACR systems, including legacy and current chemistries. Its IP54-rated sensor resists moisture and oil, so it performs well in typical maintenance and repair environments.

• Works with CFCs, HCFCs, HFCs, HFOs and common blends
• Sensor resists contamination from moisture and oil
• Durable construction suitable for field service conditions

What features help pinpoint a leak during inspection?

Several on-board indicators make locating leaks simple: a backlit LCD displays leak size and intensity, an LED tip provides visual guidance, and an audible beep changes with concentration. The 17-inch flexible probe reaches behind panels and into tight cavities where leaks often hide.

• Large backlit LCD shows concentration and trend
• LED tip plus audible beep for precise location
• 17-inch flexible probe to inspect confined spaces

How long does the detector run, and how durable is it?

The DR82 offers more than 10 hours of continuous operation on a USB-C rechargeable battery, enough for a full day of typical service work. The sensor is rated for a long service life and can resist job-site contaminants, minimizing downtime and replacement expense.

• Over 10 hours battery life via USB-C recharge
• Replaceable filter tips extend sensor life
• Sensor longevity: designed for up to 10 years of service

Who is this for: The Fieldpiece DR82 is intended for HVACR technicians, service managers, and contractors who need a dependable, highly sensitive tool to locate refrigerant leaks quickly. If you inspect split systems, heat pumps, chillers, or rooftop units and require clear visual and audible feedback plus rugged field durability, the DR82 is built to meet those demands.
