Series 477B Handheld Digital Manometer
Brand: Dwyer Instruments, LLCThe 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
