The GAS CHECK Model R2 is a portable, rechargeable leak indicator specially designed for the production leak testing of refrigeration and air conditioning components or others pressurized with a tracer gas. Light weight and cordless, the R2 will reliably locate and pinpoint leaks of CFCs and HCFCs at very low levels of leakage. The Gas Check features a choice of display units, either as a gas weight loss (gm/yr) or as a concentration of gas leakage in air (ppm). Readily calibrated against NAMAS or NIST internationally recognized standards, a unique compensating circuit automatically allows for background levels of CFCs to be subtracted out as well as limiting the effects of environmental changes (temperature and humidity). Minimum detectable leak level 3 gm/yr R134a;Response time 2 seconds, with cleardown to zero five seconds. Cordless – no trailing cable. Detector life approximately five years. Choice of standard and long probes for easy access to tight spots. Loud audible warning, brightly lighted LED visual indicator. Calibration is traceable to NAMAS or NIST standards.
