DR82 Infrared Refrigerant Leak Detector

The Fieldpiece DR82 is an infrared refrigerant leak detector built for HVAC technicians who need fast, accurate leak detection with minimal false positives. It detects HFC, HCFC, CFC, HFO refrigerants, and blends at a sensitivity of 0.03 oz/yr when stationary and 0.1 oz/yr while moving, giving you pinpoint accuracy on residential and commercial systems. The infrared sensing technology delivers stable, repeatable readings without the sensor contamination issues that plague heated diode detectors. With a 10-hour rechargeable battery, IP54 dust and water resistance, and a response time under 1 second, the DR82 is designed to work in the field, not just in the lab.

• Infrared refrigerant sensing: The DR82 uses infrared technology instead of a heated diode, which means it detects refrigerant leaks without sensor degradation or false alarms from oil, moisture, or contaminants. You get stable, consistent readings on every call without replacing expensive sensors.

• High sensitivity with adjustable levels: Detects leaks as small as 0.03 oz/yr when stationary and 0.1 oz/yr in motion, with selectable sensitivity settings (high, medium, low, turbo) so you can dial in the right detection threshold for the job. Less time wasted chasing phantom leaks.

• Large backlit LCD with numeric display and bar graph: The screen shows a real-time numeric value and a visual bar graph, plus a tip-mounted LED that lights up at the leak source. Both audible and visual alarms guide you directly to the exact point of failure.

• Rigid, non-conductive probe: The flexible wand holds its position when you bend it, so you can probe tight spaces without the tip bouncing back. Non-conductive construction keeps you safe around live electrical components.

• 10-hour rechargeable lithium-ion battery: A full charge delivers 10 hours of continuous run time, and the included USB-C charging cable and AC adapter let you recharge anywhere. No disposable batteries, no mid-job shutdowns.

• Auto and manual zero functions: The DR82 automatically zeroes itself to the ambient environment, or you can manually zero when you need a stable baseline. Recovery time is under 10 seconds, so you move from leak to leak without waiting.

• Response time under 1 second: The detector reacts to refrigerant presence in less than one second, which means you can sweep quickly without missing small leaks or waiting for the sensor to catch up.

• IP54 water and dust resistance: The housing is sealed against dust ingress and water splashes, so the detector keeps working in attics, mechanical rooms, and outdoor condensers where conditions are rough.

The DR82 detects all HFC, HCFC, CFC, and HFO refrigerants, including A1 and A2L classifications. It works on residential split systems, commercial rooftop units, refrigeration equipment, and any application where halogenated refrigerants are used. The detector ships ready to use out of the box with a rechargeable 3.7 V, 2600 mAh lithium-ion battery, USB-C charging cable, and AC charger.

The Fieldpiece DR82 is backed by a 1-year manufacturer warranty covering defects in materials and workmanship.

A: The DR82 uses infrared sensing technology instead of a consumable heated diode, which means there is no sensor element that degrades over time. The rechargeable lithium-ion battery provides 10 hours of run time per charge and is rated for hundreds of charge cycles. With proper care, the DR82 will deliver years of reliable service without sensor replacement costs.

A: The DR82 uses infrared refrigerant sensing, while older Fieldpiece models like heated diode detectors rely on a sensor that can be contaminated by oil, moisture, or other substances. The DR82 also offers a response time of under 1 second and sensitivity down to 0.03 oz/yr stationary, making it faster and more accurate than many earlier models. The rigid, non-conductive probe on the DR82 is designed to hold position in tight spaces.
