Description
The Dwyer Instruments 2002 Magnehelic Differential Pressure Gauge is a highly accurate measuring product that is used in HVAC systems to measure low differential pressures from 0 to 2 inches of water column. This gauge has a distinct diaphragm mechanism that converts pressure variations into readable units without the use of liquid manometers and thereby eradicating problems associated with evaporation and toxic fluids. It is also used commonly in HVAC systems to measure different parameters including filter resistance, fan and blower pressures and pressure drop across ducts to ensure the right airflow and energy is used.
