Features
The CLP Helium Calibrated Leaks are high-precision Standards for use in critical calibrations of leak detectors and systems, in Ultra-High Vacuum systems, and as Transfer Standards for calibrating other Helium Leaks. They feature all-welded stainless steel construction, a premium all-metal shut-off valve, a glass-permeation leak element, and are bakeable for UHV applications. The CLP Leaks are part of a family of Helium Calibrators including the GPP, GPPT, and GPC Models offered by VTI.
These models cover leak rates from 10-12 up to 10-3 atm-cc/sec and larger, as detailed in other brochures. The CLP Model is available with leak rates of 10-6 to 10-12 and is the only model made for the very low rates of 10-10 to 10-12 atm-cc/sec. VTI's experts are always eager to help you select the best model - technically and cost - for your application. Without obligation, of course.
The CLP Accu-Flow™ Calibrated Leaks are based on the principle that helium flows through certain materials at a measurable rate depending on the material thickness, driving pressure and temperature, and use Quartz or Pyrex as the permeation material for the leak element. These leaks are available with or without the leak shut-off valve, but the latter is rare, and with many types of attachment fittings such as QF (NW,KF), Conflat®, VCR® and others.
All CLP Leaks are provided with Certifications of the NIST-traceable calibrations performed in our A2LA-accredited Calibration Laboratory.
