Dwyer 477B Series Handheld Digital Manometer Precise Air Pressure Measurement

product description

Handheld Digital Manometer, 0 to 20" w.c. (0 to 4.982 kPa)

The Series 477B Handheld Digital Manometer is a versatile, hand-held, battery operated manometer 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.
