Absolute Pressure and Vacuum Gauges
Bottom Connection
Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. Also known as Torr gauges, they’re often used in laboratory applications. Gauges are barometrically independent.

Hand-Held High-Vacuum Gauges
Front
Back
Check the vacuum levels in high-vacuum pumps, valves, and chambers with this compact gauge. Use a ring and clamp (both sold separately) to connect them to another quick-clamp high-vacuum fitting, also known as KF, QF, and NW fittings. The digital display shows measurements in torr, mbar (millibar) and hPa (hectopascal).
