Liquid & Gas Pressure Measurement, ±0.5% F.S. Accuracy

SERIES 490 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 memory function allows storage of up to 40 readings for later recall and a backlight provides auxiliary lighting for hard-to-see locations. Standard are a hold feature and both visual and audible overpressure alarms. A new feature added to the Series 490 is a field adjustable damping. This allows the user to choose the level of display averaging rate corresponding to the fluctuation level common in many applications. A 9V alkaline battery is included that provides up to 100 hours of operation.

This product is in the process of being phased out, for additional ranges, see Series 490A.
