Overview

The Series 490A Hydronic Differential Pressure Manometers are versatile, handheld, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. 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.


NEW! 490A-HKIT Option is located in the Product Configurator.
