The new standard was published last December by ASHRAE to establish a method of testing for qualifying the performance of portable leak detectors designed for the detection of all CFC, HCFC, HFC, HFO, and PFC halogenated refrigerant gases. The practices and procedures in this standard cover the testing of refrigerant leak detectors intended for use in the leak testing of refrigerating, air-conditioning, and heat-pump systems and their components.
General’s RLD400 is also certified to comply with SAE J2791, J2913 and J1627 standards, and the new European standard EN14624:2012.
The RLD400 has a proprietary semiconductor sensor that allows it to detect all commercially available HFC, HFO, HC, HCFC, and CFC refrigerant gases, including many new ozone layer-friendly blends, such as R-22 and R-1234yf.
Made in America, the RLD400 is used for inspecting and maintaining mobile and stationary air conditioners, refrigerators, chillers, heat pumps, and automotive and aviation a/c systems. According to the company, it prevents compressor, evaporator, and condenser damage caused by air and moisture entering a system.
The RLD400’s proprietary semiconductor sensor has a lifespan of more than 300 hours of operation or 10 years normal use. It also has sensitivities of 0.05 oz. per year (1.4 g/year) to R-134a and 0.025 oz. per year (0.7g/year) to R-22. A true mechanical pump draws in samples, which the company noted helps increase sensitivity. Three sensitivity levels let users choose the proper level for specific environments. The device has a triple-redundant leak indication — a loud, fast beep; a bright flashing LED; and a relative digital leak size readout. The RLD400’s automatic calibration and reset ensures accurate leak readings not distorted by ambient levels. In addition, a leak test vial containing a refrigerant sample allows users to easily confirm the instrument is operating correctly.
