These pumps use compressed air to pump water or hydraulic fluid at high pressures through your system for leak testing.

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges.

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

With an accuracy of ±0.25%, these gauges are designed for critical processes that require precision.

Check pressure without permanently installing a gauge.

Use these gauges to test and calibrate transmitters, gauges, and other equipment that measures vacuum.

Twist the wing nut on these plugs to expand the seal.

Turn the cam handle to expand the seal, then snap the handle down to hold it in place.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.

Penetrate tight pipe junctures with the most flexible expansion plugs we offer.

These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line.

Use the bypass tube to add air, water, and fluid or relieve back pressure.

At least four times as accurate as standard pressure transmitters, these transmitters are ideal for use in laboratories and analytical testing applications.

Remotely track your system's pressure readings from the convenience of a smartphone or tablet. Good for preventative maintenance and route-based monitoring, these battery-powered transmitters use Bluetooth to alert you when equipment requires your attention.

For use in sanitary applications such as food processing, these transmitters are 3-A certified.

Adhere to safety standards and monitor pressure when working with high concentrations of oxygen.

The diaphragm on these transmitters mounts flush with your system’s connection, leaving no room for thick liquids to clog or harden. They’re often used to monitor pressure in wastewater, paint, and adhesive-dispensing applications.

With a pressure range common to most compressed air systems, use these transmitters to monitor your system's air pressure.

Choose these transmitters when you need reliable pressure monitoring but not high accuracy.

At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%.

For use in hazardous locations, these transmitters safely measure the difference in pressure between two process lines in flow applications—such as heat exchangers, chillers, and pumps. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

Convert both pressure and vacuum into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment.

Used in hazardous locations, these transmitters safely convert pressure and vacuum into an electrical signal to measure liquids, gases, and steam. NEC rated for safety, these transmitters are explosion proof, so they can be used in environments containing flammable gases and vapors.

These transmitters automatically compensate for error introduced into both pressure and vacuum measurements by vibrations as well as temperature fluctuations, so you do not need to program corrections for these factors into your receiving device. They convert pressure and vacuum to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment.

At least four times as accurate as standard vacuum transmitters, these transmitters sense vacuum at an accuracy of ±0.25%, making them ideal for use in laboratories and in analytical testing applications.

Account for changes in vacuum readings over time by fine-tuning the vacuum range on these transmitters.

Mount these sensors between a robot arm and a tool for precise control during delicate tasks, such as sanding or assembling small parts.

Housing is brass.

Press the side of the gauge tip against an object to record the amount of tension required to move it.

The large dial makes these gauges easy to read. They measure tension force as well as weight.

Apply your load directly to the top of these gauges to measure compression force.

Hold fine wire and filament.

Good for gripping most shapes and materials.

Measure tension force as well as weight. Also known as dynamometers.
