Tracer Gas Leak Test Standards and Components
If your application involves tracer gas technology, we offer a variety of leak standards for very low leak rate applications (as low as 1×10-10). With state-of-the-art equipment and highly trained technicians, we can provide tracer gas leak test systems that are tailored to your specific needs.
Our leak standards are all compatible with several types of tracer gas, unless indicated otherwise. While the most commonly used tracer gases are helium, hydrogen, and SF6, leak standards for other tracer gases are available upon request
Tracer Gas Leak Standard Recertification
Leak tester machines that are calibrated to a leak standard are required to be certified to provide flow rate at a specified test pressure. In addition to providing new leak standards, we offer a recertification program for our customers’ existing tracer gas leak standards.
Tracer gas leak standards are recertified in our A2LA accredited, ISO 17025 certified lab under strictly controlled processes. After the recertification process is complete, your leak tester machine is returned to you with a serialized NIST-traceable calibration certificate.
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
The CPH model calibrated leak standard is available for several different gas types and mixes. This model was developed to be compatible with Ultra-High vacuum systems and other critical applications where out gassing and background signals need to be kept to a minimum.
The TP model calibrated helium leak standard was developed to calibrate vacuum systems and helium leak detectors that test under vacuum. This model works well in an industrial environment and is the best choice for applications where the calibrated leak standard will be exposed contaminates, such as on a vacuum chamber application. Cincinnati Test Systems utilizes the finest grade of FEP available to manufacture their FEP leak elements. The leak elements have been tested at temperatures ranging from 10°C to 40°C yielding a temperature coefficient of approximately 2.5%/°C with no anomalous behavior.
The TPS model calibrated helium leak standard works equally well calibrating helium leak detectors that test under vacuum, and with helium leak detectors that sample from atmosphere utilizing a “sniffer probe”. This was accomplished by designing the TPS model with both an integral KF25 (NW25) vacuum fitting and a pin-point helium source that accepts and aligns most manufacturers “sniffer probes” with virtually no “dead volume” where helium 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. The FEP permeation type leak element is not driven by differential pressure but helium partial pressure flows helium at virtually the same rate flowing into a vacuum or flowing into normal atmospheric conditions.
