Gilson's high-quality Type B Concrete Air Meter measures entrained air of fresh concrete. Each air meter includes a calibration vessel, calibration tubes, a tamping rod, an aluminum straightedge, a syringe for water, a carrying case with die-cut foam padding, and operating instructions.
A pump with a large, easy-grip handle builds pressure in the meter quickly and is shielded to keep dirt and water out of the piston area. The brass petcocks have stainless steel ball valves for accuracy and durability and vinyl-coated handles for comfortable opening and closing. The air meters have long-lasting stainless steel clamps, which are easily adjustable and are less expensive to replace. The heat-treated cast aluminum base has a total volume of 1/4ft³ and can also be used for unit weight and yield determinations
Gilson offers the widest range of gauge types for Type B Air Meters in the industry. Every gauge exceeds the accuracy of ASTM and AASHTO requirements, and our available options vary only by the type of gauge included. The HM-30 is supplied with the exclusive Gilson Gorilla Gauge, the HM-30S is supplied with a stainless steel American-made gauge, and the HM-30D is equipped with our new digital gauge.
HM-30 features our exclusive Gorilla Gauge—a rugged, German-engineered gauge with precision jeweled movement and a high-strength Polyamide B molded housing that is waterproof and rustproof. Micro-adjustable calibration screws ensure superior accuracy and save time during calibration and maintenance procedures. The Gorilla Gauge is ANSI-rated B40 Grade 2A with accuracy ±0.5% at full scale. The dual-layer safety glass lens is sealed behind a threaded bezel with O-Ring.
HM-30S includes an accurate American-made gauge with stainless steel housing and easy, dependable operation. The sturdy industrial rack and pinion mechanism are accurate to ±1% at full scale. A threaded bezel with a gasket seals the safety glass lens.
HM-30D includes a highly accurate digital gauge with polycarbonate and ABS plastic, an IP67-rated enclosure that is weatherproof, and encased by a protective rubber boot. The Digital Gauge has a backlit LCD screen and is highly accurate with a % air content of ±0.1% at full scale.
