A four-digit LCD display allows for easy reading of measurements. The LCD shuts off after an hour to extend battery life. Also known as compound gauges, these measure both pressure and vacuum. Use them with pumps, filters, regulators, compressors, and in suction and process lines.

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).

Electric Ultra-High-Vacuum Pumps

Achieve vacuum levels up to 1 x 10 ^-12 torr with these ultra-high-vacuum pumps. Each unit includes two pumps—a diaphragm pump and a turbomolecular pump—that work together to create extremely high levels of vacuum in your chamber. The turbomolecular pump meets IP54 for protection in damp and dusty environments. Units are compact, so they fit on top of a workbench or table.

Pumps are ready to use as soon as they’re plugged in and connected to a chamber. Since they don’t use oil, they won’t introduce contaminants into your system. They hardly vibrate, minimizing interference with sensitive instruments and measurement devices.

Pumps with claw-clamp intake connections require a ring and four double-claw clamps (all sold separately) to connect to other components. Claw-clamp connections are also known as ISO-K fittings. These pumps include a gauge with quick-clamp connections, which requires a quick clamp and a ring (both sold separately) to connect. Quick-clamp connections are also known as KF fittings.

Pumps with flanged intake connections and the included gauge each require a gasket (sold separately) to connect to your chamber. Flanged connections are also known as CF fittings.
