Durablock® Air Velocity Gage Kits Series 100 AV

   
 

Designed to measure air velocity, static pressure, vacuum or differential pressure, where the additional range of the 400 Series gages is not reuired. Series 100 Gages offer superb accuracy combined with portability. In Dwyer's Durablock® precision machined solid acrylic plastic construction, the wells and inclined bore are machined to tolerances of ±.0002".

 

Design and service features:

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 Gage 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 described below, 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 gage oil, instruction card H-7, Bulletin H-11 and (see bottom of page) magnetic mounting clips, air velocity calculator slide rule and carrying case, (plastic with models 102 and 115, steel with model 125).

  Standard Equipment for Dwyer Solid Plastic Portable Manometers

Magneclips for Instant Mounting on Any Steel Surface
These mounting magnets are supplied as part of each Dwyer Durablock® solid plastic portable gage. Just touch magnets to any vertical steel surface - gage "stays put" until manually detached.

Molded Nylon Rapid Shut-Off Tubing Connectors
An exclusive Dwyer feature. Leakproof, corrosion-proof, virtually unbreakable. Requires just one turn to open or close. O-rings prevent leaks and provide positive shut-off. Body is easily removed to add fluid or to clean.

Dwyer Air Velocity Calculator
Slide rule easily calculates air velocity and compensates for temperature and pressure variations. Shows velocity pressure from .01" to 10" water column, velocities from 400 to 20,000 f.p.m., etc. Furnished as a standard accessory with all Dwyer Durablock® solid plastic air velocity gages.

Foam-lines Carrying Cases
Most Dwyer portable air velocity gages are furnished with cases of high density polyethylene. Model No. 125-AV has a steel case. Cases have a resilient polyurethane plastic foam lining to protect and cushion gage and accessories.
