Dwyer Instruments 2002-LT Differential Pressure Gauge 0-2" WC 1/8" FPT LT

The Dwyer Instruments 2002-LT Differential Pressure Gauge LT measures pressure difference between the connected points in compatible air or gas systems. Its 0-2 inch water-column range indicates low differential pressures, while the 1/8" female pipe thread provide the specified connection for compatible tubing or fittings. The gauge responds to pressure differences and displays the resulting reading on its dial. In HVAC systems, it can monitor airflow, filter loading, or duct pressure across connected points. Proper installation connects the high- and low-pressure ports to the corresponding positions. This provides direct pressure readings for system adjustment, airflow verification, and operating-condition monitoring.
