The CPS model calibrated leak standard is available for several different gas types and mixes. This model was developed to accurately calibrate “Sniffer” type leak detectors. This type of leak detector samples from atmospheric conditions via a “Sniffer Probe” Assembly. Calibrated leak standards with shut-off valves should not be used to calibrate a “Sniffer Type” leak detector. This model is available in leak rates ranging from 10-5 to 10-2 atm-cc/s
