Dwyer Instruments 2001 Magnehelic Differential Pressure Gauge 0-1" WC

The Dwyer Instruments 2001 Magnehelic Differential Pressure Gauge is a highly accurate part used in HVAc systems to measure low differential pressures up to 0-6 inches WC. This gauge uses a diaphragm mechanism to convert pressure variations into readable units of measure without the problems of fluid evaporation or spoiled inherent in manometers. In HVAC systems it is least but most valuable as it captures pressure differences across filters, ducts, and fans for proper measurement of airflow together with energy usage. The gauge construction is high-quality and it is not easily affected by shock or vibration hence can be used in different conditions.
