Manometers

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.

Precision machined 1" thick solid acrylic plastic, virtually unbreakable and free of distortion. The fluid bore is precision drilled to ±0.0002" to assure life long accuracy. The scale is mirror polished chrome plated brass to assure parallax free reading by alignment of the meniscus with its reflection.

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.

Combination Inclined/Vertical Manometer. Dwyer Durablock precision machined solid acrylic plastic construction is virtually indestructible. Has both inclined section for high accuracy and vertical section for extended range. Pressure marked in black, Velocity in red figures. Easy to read - no reference tables needed.

Dwyer solid plastic portable manometers are precision instruments in inclined and vertical (well-type) styles for the measurement of static pressure, vacuum or differential pressure. Suitable for Total Pressures Up to 100 psig, Temperatures Up to 150°F, Accuracy ±2% of Full Scale (1% on Model 115 Only).

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

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.

Designed to meet the need for a direct reading single column instrument providing highly accurate pressure readings; positive, negative or differential. Dwyer manometers have no hidden wells or packing glands. These are constructed of shatter-proof clear plastic tubing permanently bonded to well assemblies with leak-proof glued joints.

Versatile, hand-held, battery operated manometers available in several basic ranges for positive or positive differential pressure measurement and can tolerate most liquid media compatible with 316LSS. A memory function allows storage of up to 40 readings for later recall and a backlight provides auxiliary lighting for hard-to-see locations.
