NETHERLANDS: Two new refrigerant leak detectors – an infrared model and a heated diode version – have been announced by Fieldpiece Instruments.
Designed for field use, they are said to be 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. Long-lasting batteries are said to enable a full day of testing.
Both detectors have audible alarms as well as a flashing lighted tip for multiple refrigerant detection. There is an option of mute the audible alarm.
The infrared model DR82EUR offers sensitivity of <1 gram per year. Being infrared it senses a change in refrigerant levels so the user doesn’t have to manually change the sensitivity. The sensor is designed to last about ten years. Also, the DR82EUR has the added protection of a replaceable water-blocking filter that keeps moisture and contaminants from reaching the sensor, preventing contaminant-related failure.
The new DR58EUR heated diode leak detector has a state-of-the-art heated diode sensor that is said to be very sensitive to CFCs, HFCs, HCFCs, HFOs, and blends, delivering sensitivity better than 1 gram per year. It 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, the manufacturer says.
The large LCD display shows a numerical value on leak size and a bar graph indicating the intensity of the leak.
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 20cm long. Both units are IP54 water resistant for durability.
Both units come standard with a blow-moulded carrying case, USB charging cable and wall adapter, and five replacement filter tips.
