Fieldpiece DR82 Infrared Refrigerant Leak Detector

Description

The Fieldpiece DR82 Infrared (IR) Refrigerant Leak Detector is a compact and rugged device designed to quickly find refrigerant leaks in the field. Its 10-year IR sensor detects all HFC, HCFC, CFC, HFO, and blends. The detector features multiple indicators and a sensitivity that is 20 times higher than soap bubbles, allowing for the detection of even the smallest leaks in various environments. A red LED flashes at the tip, enabling users to keep their eyes on the target. The large bars on the backlit LCD are easily visible in both bright sunlight and low light conditions, and the numerical value provides an additional digit of resolution.

Unlike conventional leak detectors, the DR82 offers full control with both automatic (AZERO) and manual (MZERO) zero modes. The large, rechargeable Li-ion battery provides over 10 hours of continuous operation and can be conveniently charged via USB-C. Replaceable tips filter out water and dust, while also allowing access to tight spots. The device is housed in a ruggedized IP54 casing, making it suitable for field use.

Warnings

Inhalation of high concentrations of refrigerant vapor can block oxygen to the brain causing injury or death.

Do not use this device in a combustible gas atmosphere or with A3 refrigerants such as R-290, propane or R-600, isobutane.

Do not block exhaust port on the device, or it will not function properly.

Quick Start

1. Move to a refrigerant-free environment and hold until your DR82 powers on.
2. Allow warm-up (calibration) to complete.
3. Begin searching for the leak source. Move the tip slowly (~3 inches/sec) and as closely as possible to the suspected refrigerant line.
4. Search until refrigerant gas is detected. The red light flashes, an audible alarm triggers, and the display indicates the relative gas concentration.
5. Confirm leak source. Move tip away from alarm location for a few seconds to clear the sensor. Return tip back to the suspected leak, looking for the highest value.

Maintenance

CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents.

BATTERY CHARGING: Recharge the internal battery as needed using the USB-C cable. In addition to the AC plug, most generic USB ports supply enough power to charge. The long-life Li-ion rechargeable battery is permanently installed. To maximize battery life, minimize time spent at 100% full or 0% full.

FILTER REPLACEMENT: The hydrophobic filter is built into the replaceable tip and should be replaced periodically to maximize sensor life and performance. Five filtered tips (RFT6) are included. Unscrew the tip to remove.

Functionality Test

Use a refrigerant tank and a cap to check if your DR82 is detecting refrigerant properly.

1. Tightly cap a refrigerant tank port to seal it.
2. Open valve to coat the inside of the cap, then close the valve.
3. With DR82 set to high sensitivity (H), remove the cap and wave the tip over the cap. You should see a very large leak size of approximately "99" and a full bar graph. If not, the filtered tip may need to be replaced.

Operation

Power

Press >1 second to toggle power.

Backlight

Press to toggle the blue backlight.

Zero Modes (AZERO/MZERO)

DR82 starts up in automatic zero mode (AZERO), which sets a new zero point every 4-5 seconds, indicated by a double beep. Moving closer to the leak source will show the relative increase in concentration, triggering the alarm. Conversely, stopping at or moving away from the leak source will not trigger a response.

Press MANUAL/AUTO >1 second to toggle manual zero mode (MZERO). DR82 does not zero automatically while MZERO is displayed and will continue to alarm and display the relative leak size.

Zero Set

In manual zero mode (MZERO), press ZERO to initiate a 10-second calibration, during which "Zeroing" is displayed. For best performance, remain stationary until calibration finishes.

Numerical Leak Size Indicator with Bar Graph

The number is the relative concentration of refrigerant gas (0-99 units). The bar graph shows the same measurement in steps of 10 units for easy monitoring. The higher the number, the higher the concentration of gas being measured and the closer you are to the exact leak location.

Maximum Mode

Press MAX ON/OFF >1 second to toggle max mode. When max mode is on, the highest leak size detected is continually recorded. The recorded max is cleared when the sensitivity is changed or if manually zeroed.

Sensitivity (H/M/L/T)

DR82 starts up in high sensitivity (H), which is recommended for most situations. When leaks are difficult to pinpoint due to excess triggering or sensor saturation, press SENSITIVITY to cycle to another sensitivity (Medium/Low/Turbo). Turbo is extremely sensitive and may false trigger from abrupt motion or small changes in gas content.

Mute ?

Press ZERO and SENSITIVITY simultaneously to toggle the speaker.

Red Leak Indicator LED

In most situations, the red LED at the tip is easier to monitor than the display. Because the blink rate increases as the relative concentration increases, many leaks can be found without ever viewing the display.

Limited Warranty

This leak detector is warranted against defects in material and workmanship for one year from date of purchase from an authorized Fieldpiece dealer. Fieldpiece will replace or repair the defective unit, at its option, subject to verification of the defect.
