Solid Acrylic Plastic Inclined Manometer, For Industrial Use, Air Filter Gage, Display Type : Analog

inclined manometer

dwyer® durablock® series 250-af gages are precision machined 1" thick solid acrylic plastic, virtually unbreakable and free of distortion. The fluid bore is precision drilled to ±.0002" to assure life long accuracy. A glass spirit level is built into the body and encapsulated to prevent damage or tampering. The scale is mirror polished chrome plated brass to assure parallax free reading by alignment of the meniscus with its reflection. Safety traps are incorporated in the body to prevent loss of fluid due to pressure surges. Red and green signal flags indicate clearly when a filter change is necessary. Gages are suitable for use in ambient temperatures of -20 to 150°f. Connection fittings are positively sealed by "o" rings but easily removed for zeroing or addition of fluid. Furnished complete with instructions.

specifications

for architects and engineers

• an air filter gage for measuring the resistance to air flow through the filters shall be installed, one for each bank of filters. The gage shall be of inclined tube differential type (equipped with vent valves for zeroing) shall be of solid acrylic plastic construction with built-in level vial (and over pressure safety traps 250 series only), shall have an adjustable mirror-polished scale, shall be furnished complete with two 5-foot lengths 1/4" tubing, two static pressure tips, mounting hardware, additional bottle of red gage fluid and instructions.

features

• high accuracy and easy to use, making it a dependable device for many years of service
• easy to read polished inclined scale allows minute pressure differences to be read
• no moving parts mean no calibration or nothing to wear out
