Wet/Wet Handheld Digital Manometer
Series 490A
Liquid & Gas Pressure Measurement, ±0.5% FS Accuracy. The SERIES 490A Digital Manometers are versatile, hand-held, 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.
