Series 490 Wet/Wet Handheld Digital Manometer

Liquid & Gas Pressure Measurement, ±0.5% F.S. Accuracy
 
Features:
  • Measures Virtually any Liquid Media Compatible with 316L Stainless Steel.
  • Instant Selection from up to Seven English/Metric Units.
  • Stores 20 Readings in Memory for Later Reference.
  • Both Audible and Visual Overpressure Alarms.
  • Operates up to 100 Hours on a Single 9 Volt Battery
 
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.
