Differential Gauges

Read product description

A differential gauge is a device designed to measure the difference in pressure between two pressure sources. This can be on gas, air or liquid applications. When installed, one port is connected on the low side and the other on the high side. This will show a pressure drop indicated on the display.

In addition to our range of standard ‘off the shelf’ instruments we can also supply to your required specification including non-standard connections and even customised dials featuring your company logo.
