Magnehelic Series 2000 Differential Gauge

Mechanical differential pressure gauge for filter monitoring and room pressurisation.

Where it fits

A mechanical gauge that needs no power and gives a filter status an operator can read from across the plant room. Still the default for filter differential and cleanroom pressurisation because it keeps indicating when the instrument air and the 24 V both fail.
