About Pressure Gauges

Vibration- and Corrosion-Resistant
Pressure and Vacuum Gauges

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial that reduces needle flutter.

Pressure and Vacuum Gauges

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

Corrosion-Resistant Pressure
and Vacuum Gauges

A 304 stainless steel case coupled with 316 stainless steel connection threads provide protection from corrosive environments.

Vibration-Resistant Pressure
and Vacuum Gauges

A glycerin-filled dial reduces needle flutter for precise readings in high-vibration applications.

Absolute Pressure
and Vacuum Gauges

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They are also known as Torr gauges.

Solar-Powered Digital
Pressure and Vacuum Gauges

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. Gauges have a digital display for easy reading of measurements.

Refrigeration Pressure
and Vacuum Gauges

Often used with chillers and in refrigeration systems, these gauges display the temperature of ammonia relative to the pressure measurement.

Digital Pressure and Vacuum Gauges

A digital display allows for easy reading of measurements.

3-in-1 Pressure and Vacuum Gauges

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

Vacuum Gauges

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

Ultra-Low Vacuum Gauges

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

Vibration- and Corrosion-Resistant
Vacuum Gauges

Designed for harsh environments prone to vibration, these gauges pair a corrosion-resistant 304 stainless steel case with a glycerin-filled dial to reduce needle flutter.

Corrosion-Resistant Vacuum Gauges

The case and connection threads are stainless steel for protection in corrosive environments.

Hand-Held High-Vacuum Gauges

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

Vibration-Resistant Vacuum Gauges

A glycerin-filled dial reduces needle flutter for precise readings in high-vibration applications.

Low-Pressure Differential
Gauges with Dial Indicator

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.

Differential Pressure
and Vacuum Gauges

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

Differential Pressure and Vacuum
Gauges with Digital Display

Gauges have a digital display for easy reading of measurements.

Solar-Powered Digital
High-Accuracy Pressure Gauges

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. They have a digital display for easy reading of measurements.

Digital High-Accuracy
Pressure Gauges

A digital display allows for easy reading of measurements.

Pressure and Vacuum Transmitters

Absolute Pressure Transmitters

Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature.

Washdown Pressure Transmitters

For use in wet environments, these transmitters are rated NEMA 4X for protection from washdowns and corrosion.

Absolute Pressure Transmitters
for Development Boards

Measure your equipment’s pressure and send the data directly to a development board or single-board computer. Also known as transducers, these transmitters convert pressure into an electrical I²C signal and transmit it to your board.

Pressure and Vacuum Transmitters

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.

High-Accuracy Pressure
and Vacuum Transmitters

With an accuracy of ±0.25%, use these transmitters in applications that require highly accurate measurement of both pressure and vacuum, such as activating vacuum pumps.

Sanitary Easy-Setup Pressure
and Vacuum Transmitters

Designed for sanitary environments, these transmitters automatically compensate for error in vacuum and pressure measurements caused by vibration and temperature fluctuations, so you don’t need to program corrections into your receiving device.

Hazardous Location Easy-Setup
Pressure and Vacuum 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.

Easy-Setup Pressure
and Vacuum Transmitters

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.

Remote Displays for
Pressure Transmitters

Monitor pressure in your system from a distance by using this display in conjunction with pressure transmitters.

Sanitary Easy-Setup
Vacuum Transmitters

Monitor and control equipment in food-processing and pharmaceutical plants—these transmitters convert vacuum into electrical signals for receiving devices and have a 3-A certified sanitary design. They automatically compensate for vibration and temperature changes, saving you the effort of programming manual corrections.

Washdown Vacuum Transmitters

These transmitters are rated NEMA 4X for protection from washdowns and corrosion.

High-Accuracy Vacuum Transmitters

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.

Vacuum Transmitters

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.

Pressure Testing

Manual Pumps for
Testing and Calibration

Manually pump air, water, or hydraulic fluid through your system so you can test for leaks.

Test Gauges for Vacuum

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

Electric Ultra-High-Vacuum Pumps

Achieve vacuum levels up to 1 x 10 ^-12 torr with these ultra-high-vacuum pumps.

Vacuum Aspiration Systems

Vacuum up liquid for sampling and disposal using these compact and portable systems.
