HT Products - Calibrated Reference Leak - LV-ZV HT Products - Calibrated Reference Leak - LV-ZV

Included in the range of Calibrated Reference Leaks applicable to high vacuum systems is the ‘Zero Volume’ Reference Leak. High Precision, Full Mass Range Calibrations, Stable Pressure on Activation.

Designed for calibrating quadrupole mass spectrometer gas analysers and vacuum inlet systems, the leak consists of the following:

75cc Stainless Steel Reservoir - In which is contained the calibration gas, typically 1000 p.p.m of Helium, Krypton and Xenon in Argon at 20 Bar.

Purpose Built High-Vacuum Valve - An air operated valve to isolate the gas supply. The valve is attached to the vacuum system via a DN16-CF-R coupling.

Vacuum Sintered Leak - The Leak forms part of the valve seating which minimises the gas held in the aperture behind the valve. Therefore when the valve is opened under vacuum the change in the system’s total pressure is barely perceptible.

The valve is air-actuated as standard but a manually actuated valve is also available. Other gases and mixtures can be supplied as required
