These gauges have a red needle that indicates the highest pressure reached since the last setting. They have a liquid-filled dial that reduces needle flutter for precise readings in high-vibration applications.

Check the pressure on your drinking water system with these gauges—they meet NSF/ANSI Standard 61 for safe use with potable water.

Designed for use with boilers, these gauges measure pressure and temperature simultaneously.

Use in low-pressure applications up to 160 psi.

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

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.

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

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.

Safely monitor liquid, gas, and steam pressure in hazardous locations with these transmitters. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

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

FM approved and CSA certified for use in hazardous locations, these transmitters monitor pressure where combustible fumes may be present.

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.

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.

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.

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.

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.

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.

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