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

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

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

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.

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

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.

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

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

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

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

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.

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.

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.
