The Series 477B Handheld Digital Manometers are versatile, hand-held, battery operated manometers available in several basic ranges from 0 in W.C. - 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.

• Precise 0.1% FS accuracy provides four times better accuracy than most standard manometer/gages
• Aluminum housing protects instrument against damage
• 40 readings in internal memory reduces time to record data
