These Manometers combine the inherent accuracy of the simple "U" Tube with the durability of tough, long-lasting plastic construction. Columns are of .375" O.D. flexible and shatter proof clear butyrate tubing. Stark white scales have graduations and numbers silkscreen-printed in black for maximum legibility.
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 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.
