 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 (0-34500 kPa). Units are highly accurate
(±0.5% FS) for positive or positive differential pressure
measurement and can tolerate most liquid media compatible with
316L stainless steel.
You can select from up to seven common English and metric
pressure units (PSI, in. H2O, in. Hg, mm Hg, kPa, bar or mbar)
so conversions are not necessary. A memory function allows
storage of up to 20 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 overpressure
alarms. A 9V alkaline battery is included that provides up
to 100 hours of operation. Units have dual 1/8" female
NPT connections.
