Air meter with detachable probes measures air velocity in fpmIncludes a slide rule calculator for determining static pressure in inches of w.c.Dual-scale shows low- and high-range readings and has red graduations for distinct readingsMade of hard plastic to resist breakage and provide a clear view of the scaleIncludes return grille probe, supply grille probe, angle connector, rubber tubing, air velocity calculator, pipe cleaners and nylon bristles for cleaning, carrying case, and instructionsSimple and quick, the M460 Air Meter is popular for servicing air conditioning, heating and ventilating equipment. Direct reading velocity and static pressure scales — both low and high ranges — show supply and return grille velocities, furnace draft, pressure drop across filters, etc. The M460 gives consistent, accurate results with no tedious calibration. Rugged plastic for rough daily use.
