DESCRIPTIONThe Dwyer 490 Series Wet/Wet Digital Manometers are ver-satile, handheld, and battery operated. Units are highly accurate(0.5% FS) for positive or positive-differential pressure mea-surement, and they can tolerate most liquid media compatiblewith 316L stainless steel. There are seven common English andmetric pressure units (psi, "H2O, "Hg, mm Hg, kPa, Bar, ormBar), so conversions are not necessary.

Service Compatible, non-combustible gasesand liquids
