Dwyer 115-AV Offers

• Designed to measure air velocity, static pressure, vacuum or differential pressure.
• Offer superb accuracy combined with portability.
• The Dwyer® Durablock® precision machined solid acrylic plastic construction, the wells and inclined bore are machined to tolerances of ±.0002".
• Plastic Body - A 1" thick solid acrylic block, virtually unbreakable. It is stable and free of the danger of distortion.
• Drilled Bore - Permanently free of bends - never requires recalibration due to distortion.
• Reflective Chrome Finish Scales - Easily eliminates parallax errors in reading.
• Adjustable, with thumbscrew locking for easy zeroing. (Model 125 AV uses screw plunger to adjust zero setting).
• Red Gauge Oil - .826 specific gravity. Forms a well-shaped, easy-to-read meniscus - the result of high wetability.
• Leveling Adjustment - Screw allows quick, accurate leveling. Integral ground glass bubble level provides ready reference.

Complete Air Velocity Kits Include:

Dwyer® Inclined Manometer, stainless steel Pitot tube (12" with Models 102 AV & 115 AV, 24" with Model 125 AV), two 9' lengths of rubber tubing with connectors, additional red gauge oil, instruction card H-7, Bulletin H-11 and magnetic mounting clips, air velocity calculator slide rule and carrying case, (plastic with Models 102 and 115, steel with Model 125).

Features

• Inclined and vertical (well-type) styles for the measurement of static pressure, vacuum or differential pressure
• To assure the accuracy required in instruments of this type, all machining of bores and wells is to the highest standards of precision
• Selected Gauge Oil with high wetability characteristics forms a consistent, well shaped meniscus for easy readability
• Adjustable Reflective Chrome Finish Scales with thumbscrew locking for easy zeroing
• Parallax-Free Reading for maximum accuracy and consistency is achieved by simply aligning the meniscus with its image reflected in the polished aluminum scale
