                      Product Overview

                      490A-6 is a series 490A hydronic differential pressure manometer. It is a versatile, hand-held, battery operated manometer can tolerate most liquid media compatible with 316L stainless steel. A new feature added to the Series 490A is a field adjustable damping, which allows the user to choose the level of display averaging rate corresponding to the fluctuation level common in many applications. Typical applications include chiller to coils for freeze protection, hydronic valve balancing, measure pressure drop across pumps and refrigerant pressure testing.

                      • Range 0 to 200.0psi
                      • Seven user-selectable English and metric units
