These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings.

Unlike other gauges that have multiple moving parts that can shake loose, these have only one internal part. They are the most shock-resistant gauges we offer.

These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings. They have a liquid-filled dial that reduces needle flutter for precise readings in high-vibration applications.

These gauges can withstand both extremely cold and extremely hot temperatures.

Use in low-pressure applications up to 160 psi.

Use in high-pressure applications up to 2,000 psi.

Use these gauges with vacuum pumps, packaging equipment, and in suction lines to measure and display vacuum.

Accommodate applications with a vacuum range of -100 in. of H₂O to 0 in. of H₂O.

Check the vacuum levels in high-vacuum pumps, valves, and chambers with this compact gauge.

A band of green, yellow, and red provides a clear indication of changes in differential pressure.

Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure.

Also known as compound gauges, these measure both pressure and vacuum.

These portable gauges have three different dials to display pressure and vacuum measurements on a low, medium, and high scale.

A digital display allows for easy reading of measurements.

Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements.

Also known as isolators or diaphragm seals, these protect gauges from corrosive process media.

Also known as pitot tubes, these can be used with manometers to measure air flow rate.

Convert 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 vacuum or control equipment.

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

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.

Monitor your system’s pressure and vacuum from a smartphone or tablet via Bluetooth. These battery-powered transmitters send alerts if equipment requires your attention, so they’re good for preventative maintenance and route-based monitoring.

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum.

Remotely monitor pressure in general purpose applications such as pumping and compressing systems.

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.

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

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. They convert pressure 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.

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.

Fine-tune the pressure range on these transmitters to account for changes in pressure readings over time.

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.

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

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

Gauges have an accuracy of ±0.25%.

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

Externally monitor the air temperature inside freezers, refrigerators, water baths, and incubators. These thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Designed for laboratory applications, these thermometers determine temperature within ±0.75° F accuracy.

Measure and store temperature readings and upload the data to a PC.

For a longer service life than thermocouple probes and more consistent readings over time, these thermometers have a resistance temperature detector (RTD) probe. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send data to smartphones and tablets via Bluetooth, so you can easily confirm your processes are functioning properly. Good for route-based monitoring and preventative maintenance.

Thick wire with ceramic insulation stands up to extreme air temperatures in forging, die casting, and heat treating.
