Cincinnati Test Systems’ compact, portable high vacuum leak test gauge uses Pirani gauge technology to deliver reliable, accurate results in any application. These precision vacuum gauges feature digital displays for easy reading. View results in Microns, Pascals, or mBar.

What is A Pirani Gauge?

The Pirani gauge, invented by Marcello Pirani in 1906, is a thermal conductivity device consisting of a heated platinum (or other metal) filament suspended in a gas-filled tube that is connected to the system that is being tested. The heated wire loses heat to the surrounding gas; if the gas pressure is reduced, the number of gas molecules colliding with the wire decreases proportionately, and the wire will lose heat more slowly. Heat loss, therefore, can be used to measure pressure changes. CTS’ precision vacuum gauges use reliable Pirani-based technology to ensure precise readings.
