Dwyer Wet/Wet Handheld Digital Manometer 490 Series

Dwyer Wet/Wet Handheld Digital Manometer

 

The Dwyer 490 Series wet/wet digital manometers are versatile, handheld, and battery operated. Units are highly accurate (±0.5% FS) for positive or positive-differential pressure measurement, and they can handle or be used with most liquid media compatible with 316L stainless steel. There are seven common English and metric pressure units (psi, "H2O, "Hg, mm Hg, kPa, Bar, or mBar), so conversions are not necessary.
