WY-20 adjustable halogen leak rate calibrator for the calibration of leak detector, leakage rate can be accurately read the surface, and through the instrument to control the two valves. From 0 to a maximum leak rate between the various sections can be freely adjusted. 

 Optional gas type (R22, R12, R134a, R407c, SF6, R600a, etc.) may also require the user of the gas species, specifically custom adjustable leak rate calibrator. 

 In order to improve the reliability of leak detector before use, leak detector must be properly calibrated. With WY-20 adjustable leak rate calibrator, available fast, simple, high accuracy results.
