Measures positive and differential positive pressure

Stores 40 readings in memory for later reference

Audible and visual overpressure alarms

Adjustable dampening feature for averaging fluctuating readings

Measures virtually any liquid or gas compatible with 316L stainless steel

The Dwyer Series 490 Digital Manometer is a versatile, hand-held, battery operated manometer available in several basic ranges from 0-15.0 psi to 0-100 psi. Units are highly accurate (±0.5% full-scale) for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316L stainless steel. Select from up to seven common English and metric pressure units: psi, in. H2O, in. Hg, mm Hg, kPa, bar or mbar. 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 features are a hold function, as well as both visual and audible overpressure alarms. A new feature added to these manometers is a field adjustable dampening.
