Designed for compressed air and gas systems, these transmitters remotely monitor vacuum.

Measure the difference in pressure between two points in flow applications, such as heating, cooling, and pumping systems.

Measure the difference in pressure between two process lines in flow applications such as heat exchangers, chillers, and pumps. These transmitters automatically compensate for error introduced by vibration as well as temperature fluctuations, so you do not need to program your receiving device to correct for these factors.

Test and calibrate transmitters, gauges, and other equipment that measures pressure.

Gauges have an accuracy of ±0.25%.

These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications.

A notch on the handle indicates when the internal NPT threads you’re checking are in tolerance.

To ensure accuracy of NPT pipe thread measurements, these gauges include a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

Install this totalizer on your grease gun to accurately measure grease dispensing and reduce waste.

The enclosure meets NEMA 4X to protect these totalizers from dust, washdowns, and corrosive liquids.

Measure the total flow volume of water in your system.

Measure the total flow volume of gasoline, diesel fuel, and kerosene.

These totalizers meet NSF/ANSI Standard 61 for use in drinking water systems.

For installation in instrument panels, these flowmeters have fittings on the back.

For protection against damage, these flowmeters have a rugged, impact-resistant case.

The prominent dial is easier to read from a distance than a standard scale.

Instead of a scale, these flowmeters have a prominent dial that’s easy to see from a distance. Dial displays readings in gallons.

For faster installation and disconnection than standard flowmeters for water, these flowmeters have union nuts on both ends.

Union nuts let you quickly install and disconnect these flowmeters from your system for maintenance.

For protection from dust, washdowns, and corrosion, these flowmeters have an enclosure that meets NEMA 4X.

Fittings on the back let you install these flowmeters in instrument panels.

The indicator moves when flow is present, so it’s easy to visually confirm flow from a distance.

A large tubular window provides an unobstructed view of liquid color, clarity, and movement from multiple angles.

For visual confirmation of flow from a distance, these sights have a ball indicator that moves when flow is present.

To maintain a clear view of your process media without disrupting flow, twist the tubular window to clear debris and buildup with the internal wipers.
