Air Entrainment Meters
54-C0170/L: Air entrainment meter, water column type, 5 l cap., complete with calibration cylinder apparatus.
The water column type consists essentially of a stainless steel flanged cylindrical vessel with cover assembly, incorporating the measuring cylinder, pressure gauge and valves. Supplied complete with hand pump and calibration cylinder apparatus which is essential for adjustment to site barometric pressure.
The cylindrical vessel of all models can also be used as unit weight measure for fresh concrete for density determination.
54-C0170/D: Air entrainment meter, pressure gauge type, 8 l cap.
54-C0170/F: Air entrainment meter, pressure gauge type, 7 l cap.
The gauge meter models consists essentially of a flanged cylindrical vessel , complete with cover assembly incorporating a pressure gauge, air pump and valves. They feature:
Gilson's high-quality Type B Concrete Air Meter for concrete air content determination has many improvements that make it an excellent buy. We tend to have them in stock.
HM-30: Gilson Concrete Air Meter w/ Gorilla Gauge
The HM-30 model features exclusive Gorilla Gauge, a rugged German-engineered gauge with precision jeweled movement and a high-strength Polymid 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 ±1/2% of full scale. The dual-layer safety glass lens is sealed behind a threaded bezel with O-ring.
Long-lasting stainless steel clamps adjust quickly and are less expensive to replace.
A built-in pump with 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 pressure chamber volume is 1/4ft³ and can also be used for unit weight and yield determinations.
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 meter with all components securely in die-cut foam padding.
Meets Standards: AASHTO T 152 , ASTM C231
