250 AF Inclined Manometer Air Filter Gages 02486

Dwyer® Durablock®Series 250-AF Gages are precision machined 1 in thick solid acrylic plastic, virtually unbreakable and free of distortion. The fluid bore is precision drilled to ± 0.0002 in 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°F - 150°F. Connection fittings are positively sealed by "O" rings but easily removed for zeroing or addition of fluid. Furnished complete with instructions.

Economy Model 452-AF is similar to 250 Series except that it is not equipped with over pressure traps. Two A-324 1/4 in compression fittings are included with each gage but not shown. Bodies are of 5/8 in thick acrylic and scales are mirror polished, epoxy coated aluminum.

• 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
