Hand-Held High-Vacuum Gauges
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).
- For Use With: Air
- Accuracy: ±10% @ 7.5 to 7.5 × 10 -3 torr, ±30% @ 75 to 7.5 torr

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