Dwyer 490A Hydronic Differential Pressure Manometer Kit

The Dwyer 490A Hydronic Differential Pressure Manometer Kit is a portable digital differential pressure manometer designed for hydronic system balancing and pressure testing. It delivers up to ±0.5% full-scale accuracy and supports seven selectable pressure units in both metric and imperial formats.

Digital dampening keeps readings stable, while automatic resolution adjustment improves measurement accuracy. A bright backlit display allows easy reading in low-light environments. The rugged kit includes a hard carry case and all required accessories for field work.

The 490A Hydronic Differential Pressure Manometer Kit stores up to 40 readings and works with liquids compatible with 316L stainless steel components. It is ideal for checking pressure across pumps, balancing hydronic valves, and protecting chillers from freezing conditions.
