The GP model helium calibrated leak standard was developed to be compatible with Ultra-High vacuum systems. This model is the calibrated helium leak of choice for 10-9 and 10-10 atm-cc/s leak rates and critical applications where out gassing and background signals need to be kept to a minimum. . This model is available in leak rates ranging from 10-10 to 10-5 atm-cc/s (Other rates available upon request).
The CPO model calibrated leak standard is an open style calibrated leak with no gas reservoir, the customer supplies gas from a regulated gas supply. This model is available for several different gas types and gas mixes. This model is available with all of the standard “Orifice” leak holder assemblies. The CPO model is also available with fittings suitable for high pressure or ultra high vacuum applications. The CPO model is available in leak rates ranging from 10-7 to 10-1 atm-cc/s (Other inlet and outlet fittings available upon request).
The CPV model calibrated leak standard is available for several different gas types and mixes. The CPV model was developed to calibrate “sniffer” type leak detectors. The CPV model is often used to verify the concentration of a tracer gas in a mix, and to calibrate hydrogen leak detectors. The CPV model features a pin-point gas source that accepts and aligns most manufacturers “sniffer probes” with virtually no “dead volume” where tracer gases can accumulate and cause inconsistent readings. Calibrated helium leak standards with shut-off valves and should not be used to calibrate a “Sniffer Type” leak detector.
