Magnehelic Guage
Accurate, Reliable, Industry-Standard Performance
The Magnehelic Gauge is an industry-standard instrument designed for measuring a wide range of pressures, including fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels in bubbler systems, and pressures in fluidic systems.
It features a highly sensitive diaphragm that accurately responds to pressure variations. As pressure is applied, the diaphragm moves, causing the gauge pointer to display precise readings on the dial.
For optimal accuracy, the Magnehelic Gauge must be installed in a level, vertical position.
