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

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

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.

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.

Gauges have a digital display for easy reading of measurements.

Gauges have a digital display for easy reading of measurements.

Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment.

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.

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.

Read pressure directly at the source and send data remotely with one device.

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.

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.

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

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

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

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.

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.

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

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

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.

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

All-stainless steel construction makes these gauges suitable for testing and calibrating in corrosive environments.

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

Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves.

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

Rated for at least six times the pressure of standard flowmeters for air, these can withstand pressures of at least 600 psi.

Choose these flowmeters for highly accurate flow rate measurements.

A 304 stainless steel case protects these flowmeters from blows that could shatter the glass body.

Calibrated for compressed air.

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside.

These switches have a fixed set point for applications with consistent flow.

For installation in environments with flammable gases and combustible dust, these flow switches are UL listed for use in hazardous locations.

For use in food-processing applications, this thermometer meets NSF/ANSI standards and includes a thermocouple probe with a pointed tip to pierce dense meats and frozen foods.

These thermometers have a thermocouple probe that can handle extreme temperatures, and come with a calibration certificate traceable to NIST that states they have passed a test for accuracy.

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe.

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

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

An armored stainless steel cable protects wiring from corrosion and damage in humid conditions and harsh environments.

Use these RTD probes for more stable air-temperature readings than thermocouple probes.
