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 from 0-15.0 psi (0-100 kPa)to 0-500 psi (0-3450 kPa).Units are highly accurate (±0.5%FS)for positive or positive differential pressure measurement and can tolerate most liquid media com-patible with 316LSS.

You can select from up to seven common English and metricpressure units (psi,in.H2 0,in.Hg,mm Hg,kPa,bar or mbar) so conversions are not necessary.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 over-pressure alarms.A new feature added to the Series 490 is field adjustable dampening.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.Units have dual 1/8 ? female NPT connections..
