Dwyer Instruments 477B-5 | Handheld digital manometer | 0 to 30 psi (0 to 206.9 kPa)
The battery-operated, handheld, digital manometers in Series 477B are designed to be versatile and come in multiple basic ranges, ranging from 0-20 in w.c. to 100 psi. All models have an accuracy of ±0.10% of full scale for measuring positive, negative, or differential pressures. It is not necessary to convert because you have a choice of up to seven standard English and metric pressure units. Up to 40 readings can be stored for later reference using the memory feature, and a backlight adds extra lighting to areas that are difficult to see. A hold feature and audio and visual overpressure alerts are also included as standard features.
