Product Description
Series 490A Hydronic Differential Pressure Manometer (Model # 490A-1) (0 to 15 PSI) (0 To 103.4 KPA)
* Liquid & Gas Pressure Measurement, ±0.5% FS Accuracy
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.
