Quickly indicates low air or non-corrosive gas pressures either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. May be used with Hydrogen; order a Buna-N diaphragm, pressures must be less than 35 psi.
The 476A series digital manometers can be used to measure low pressures from -20 to 20 "w.c. with ±1.5% FS accuracy. The 478A digital manometers can be used to measure positive, negative, or differential pressures. Both are constructed of an extruded aluminum case for exceptional durability.
2.5" diameter dial pressure gauges. Dual english/metric scales with ±1.5% accuracy.
Measures positive, negative, or differential pressure of air and natural gases in ranges from 1 "w.c. (0.249 kPa) to 150 psid (10.34 bar). The dual push pads on the front panel control the on/off, auto-zero, and pressure unit selection, allowing for simple operation with no set up needed.
The Mark II series molded manometers are of the inclined and inclined-vertical types. Both gauge types are capable of pressure measurements above and below atmospheric as well as differential pressure measurements.
Offers 0.5% FS accuracy in a rugged, easy-to-use unit, and feature user-selectable units of measurement, allowing one gauge to be used for a variety of pressure scales. The DPGWB gauges stainless steel wetted material makes it suitable for a wide variety of liquids or gases. It comes equipped with a protective rubber boot.
