The RLS Refrigerant Leak Standards developed by VTI have been in use worldwide for over 10 years as the Standard for calibrating sniffer-type refrigerant leak detectors. These Leaks are available for all old and new Refrigerants and a wide range of leak rates from 0.01 to over 10 oz/yr. Also, each RLS has a 10:1 adjustable leak rate range (such as 0.1 to 1.0 oz/yr). VTI’s calibrations of each of these Standards are Certified to be NIST-Traceable and A2LA Accredited, and indeed they form the basis of traceability for most of the manufacturers of refrigerant detectors in the world.
The RLS has a reservoir of liquid refrigerant that is interconnected with a valve to the vapor reservoir to provide a convenient, long time supply of vapor for the Leak. Depending on use patterns and QA requirements, these Leaks are typically sent to VTI for refill and recalibration after one to three years of use. Unlike the fragile glass capillaries sometimes used by other manufacturers, the RLS uses a crimped stainless-steel capillary leak element that is unbreakable.
