Air Meter

Gilson’s high-quality Type B Concrete Air Meter measures air entrainment from the fresh concrete sample in the base. Our HM-30 model features the exclusive Gilson Gorilla Gauge, while the new, economical HM-30S offers an American-made stainless steel gauge. Other features of the two units are identical. Long-lasting stainless steel clamps adjust quickly and are less expensive to replace. A built-in pump with a large, easy-grip handle builds pressure in the meter quickly.

It is shielded to keep dirt and water out of the piston area. Brass petcocks have stainless steel ball valves for accuracy and durability. Petcock handles are vinyl coated for more comfortable operation. The cast aluminum base volume is 1/4ft³ and can also be used for unit weight and yield determinations.

The accuracy of the Gilson air meters exceeds ASTM requirements. Calibration Vessel, Calibration Tubes, Tamping Rod, Aluminum Straightedge, Syringe for water, Carrying Case, and operating instructions are all included. The sturdy plastic carrying case holds a meter with all components securely in die-cut foam padding.
