The
Pressure Meter is used for measuring the amount of entrained air in
freshly mixed concrete. The test method equalizes a known volume of air
in the pressure chamber, with the unknown value of entrained air in the
meter’s concrete filled base. The amount of entrained air is then read
on the meter’s gauge as the direct percentage of air entrained in the
sample.
Constructed of cast aluminum, the
meter is durable yet lightweight. Four one-piece, self-locking clamps
have the proper tension for sealing the lid to the base.
A direct percentage-reading gauge with
calibration adjustments is readable to the nearest 1/10 of a percent.
The gauge is positioned for easy reading by the user.
The meter features an all brass pump
with elongated stroke to build test pressure faster with fewer strokes.
Its unique check valve eliminates “o”-ring seal problems associated with
other style pumps.
The meter comes complete with heavy
duty plastic carrying case, syringe, tamping rod, strike-off bar,
calibration vessel and tubes with instructions and parts list.
