Dwyer Series 490 Wet/Wet Handheld Digital Manometer 0 to 100 psi
-
- 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. This all
