Description
Choose the Dwyer Magnehelic differential pressure gauge for high accuracy – guaranteed within 2% of full scale – and for the wide range of 81 models to meet your exact requirements. Using Dwyer’s simple, frictionless Magnehelic motion, the gauge quickly indicates low air pressure or non-corrosive gas pressure, whether positive, negative (vacuum) or differential. The instrument is resistant to shock, vibration and overpressure and does not use gauge fluid that evaporates, freezes or causes toxic or levelling problems.
The Magnehelic is the industry standard for measuring:
- fan and blower pressure
- filter resistance
- air velocity
- furnace pressure and chimney draught
- Pressure drop at measuring discs
- liquid levels with bubble pipes
- Pressure in liquid reinforcement systems
Magnehelic also checks gas-air ratios and automatic valves and measures blood and respiratory pressure in medical equipment.
