Applications
Magnehelic gauges are used for monitoring differential pressure across filters, dampers, and ductwork in HVAC systems. Common in industrial applications for filter pressure drop indication and airflow verification. Used in compressed air systems, clean rooms, and ventilation systems where low-pressure differential measurement is required.
This Dwyer 2040C Magnehelic Differential Pressure Gauge has been inspected and is in good used condition. It was pulled from a working environment where it was previously in service. The dial face is clean and legible with the pointer intact. The cast metal housing shows surface wear and light scuffing consistent with industrial use. An equipment identification label and a calibration label are affixed to the front face. The rear housing is intact with the brass pressure port fitting present.
