Fieldpiece Instruments Introduces Two New Ultra-Sensitive Leak Detectors

Orange, Calif., May 11, 2021 – Fieldpiece Instruments, the industry leader in tool and test instruments for HVACR professionals, announces the launch of two new leak detectors, Infrared model DR82 and Heated Diode model DR58. The two new Fieldpiece leak detectors are highly sensitive, durable and more reliable than anything else on the market. Designed for field use, they are easy to read in bright sun or low indoor light with large, bright blue LCD displays for leak information. The displays include bar graphs and numerical values. In addition, they have long lasting batteries for a full day of testing, and both the leak detectors and the included case are rugged and made to last.

Designed with the HVACR pro in mind, the new leak detectors include uncompromising features such as high sensitivity, multiple refrigerant detection, and audible alarms as well as a flashing lighted tip for an easy visual indicator.  The Infrared model DR82, gives technicians superior sensitivity in the field – <0.03-ounces per year. To pinpoint the leak, the user sweeps the area with the DR82 IR Leak Detector resulting in the unit sensing a change in refrigerant levels so the user doesn’t have to manually change the sensitivity. The DR82 has the most consistent leak detection across all refrigerants making it easy for the technician to locate the leak in any situation. The Infrared sensor is designed to last about ten years, one of the longest-lasting sensors on the market today. Also, the DR82 has the added protection of a replaceable water-blocking filter that keeps moisture and contaminants from reaching the sensor, preventing contaminant-related failure. The rechargeable 10-hour lithium-ion battery powers the unit for a full day of testing.

The new DR58 Heated Diode Leak Detector has a state-of-the-art heated diode sensor that is very sensitive to CFCs, HFCs, HCFCs, HFOs, and blends, delivering sensitivity better than 0.03-ounces per year. A USB rechargeable lithium-ion battery powers the DR58 for up to 18 hours on a single charge. Technicians can check the amount of battery life left when starting up the unit and on the fly.  The DR58 triggers on absolute refrigerant concentration.  The instrument defaults to auto zeroing mode when switched on and refreshes every two seconds until a leak is detected. Technicians can also switch to manual zeroing mode to help pinpoint leaks, even in contaminated areas.

“Finding and fixing leaks on a system not only helps eliminate the venting of refrigerants into the atmosphere, it is another way to make sure charge related problems are minimized between scheduled maintenance calls. We now offer the best infrared and heated diode leak detectors in the industry,” said Charlotte Loomis, Sr. Marketing Manager, Fieldpiece.

Like all of Fieldpiece’s instruments, the new leak detectors allow HVACR pros to work more effectively with more information. Both a visual (flashing tip) and audible alarm on the wand alert the HVACR pro when a refrigerant leak is detected. The pros have the option of muting the audible alarm by pressing the two buttons. The large LCD display shows a numerical value on leak size and a bar graph indicating the intensity of the leak. The backlit LCD display can be seen in dark places or in direct sun to give the pro much needed information on the refrigerants detected and the remaining battery of the unit. A peak reading indicator features a manual reset to clear. Three sensitivity levels adjust at the push of a button to find leaks even in refrigerant contaminated environments. The units are rugged and easy to use and hold due to their compact size at only 8” long. Both units are IP54 water resistant for durability.

Both units come standard with a blow-molded carrying case, USB charging cable and wall adapter, and 5 replacement filter tips. The suggested trade price for the DR82 is $475. The suggested trade price for the DR58 is $345. They are available at distributors now. For more information about the leak detectors please visit the product page
