Dwyer Instruments 2030 Magnehelic Differential Pressure Gauge 0-30" WC

The Dwyer Instruments 2030 Magnehelic Differential Pressure Gauge is stable product that measures low differential pressures of up to 30 inches water column in HVAC systems. It uses a diaphragm conceptwhere pressure variance is converted into a dial reading with no need for a power supply, making it suitable for HVAC system use. This gauge is most useful in measuring and adjusting air pressure through filters, ducts, and fans of systems of HVACsystems in buildings. Also, it keeps the controlled clean room conditions by monitoring pressure differentials and ensuring that the composition in these areas is kept free from contamination.
