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.
As accurate as the finest laboratory "U" gauges - yet they are made to roll up compactly for easy carrying and to withstand rough usage.
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.
