The Pressure Master digital indicator is available in over 200 standard pressure ranges from 0.25-in. H 2 O through 10,000 psi. Gauge, absolute, compound and differential pressure types are offered, as well as vacuum. The indicator can display measurement data from one, or optionally two, installed pressure-sensing units simultaneously, or display temperature with a second unit. The mechanical dial gauges are designed for use in bench, panel and field applications.
Top pointer is orange, bottom pointer is black.
To measure the difference between two pressure sources, apply low pressure, then high pressure. Read differential pressure on the gauge.
