Low-Pressure Gauges for Chemicals




A plastic or stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressures.
Polypropylene and 316 stainless steel guards are more chemical resistant than PVC and CPVC guards.

Vibration- and Corrosion-Resistant Pressure and Vacuum Gauges


Back Connection
(Panel Mount)



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. Also known as compound gauges, they measure both pressure and vacuum. Use them with pumps, filters, regulators, compressors, and in suction and process lines.
