Series 477B Handheld Digital Manometer

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series 477B Handheld Digital Manometers are versatile, hand-held, battery operated manometers available in several basic ranges from 0-20 in w.c. up to 100 psi.

All models measure either positive, negative or differential pressures with ±0.10% of full scale accuracy. You can select from up to seven common English and metric pressure units so conversions are not necessary.

A memory function allows storage of up to 40 readings for later recall and a backlight provides auxiliary lighting for hard-to-see locations. Also standard are a hold feature plus both visual and audible overpressure alarms.
Features
  • Precise 0.1% Full Scale Accuracy Provides Four Times Better Accuracy than Most Standard Manometer/gauges
  • Aluminum Housing Protects Instrument Against Damage
  • 40 Readings in Internal Memory Reduces Time to Record Data
