Series 477B Handheld Digital Manometer

Precise Air Pressure Measurement, ±0.1% F.S. Accuracy

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.

Product Applications

  • Lab calibration of other pressure instruments
  • Air velocity/air flow measurements in commercial buildings
