Refillable Vacuum Reference Leak

The Refillable Vacuum Reference Leak is suitable for calibrations and experiments requiring a flow rate high enough to require a regular gas recharge. This would normally be recommended for flow rates of above 5x10-6mbl/s depending on the gas.

The reference leak has a 400cc reservoir to give a long contents life with a recharge facility available. The product is supplied with a graph of reservoir pressures to allow adjustment of the reservoir pressure to Stainless Steel Reservoir - In which is contained the calibration gas, typically Helium,Argon, Nitrogen, Hydrogen or a special calibration mix at a maximum of 16 Bar.

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.
