Description
The Forney Air Entrainment Meter measures the air content in fresh compacted concrete. It consists of 2 main parts: the base (measuring chamber) and the cover assembly. It is supplied complete with calibration set.
The cast aluminium base, of cylindrical shape, has machine-flanged rims. The interior surfaces of the base and surfaces of rims, flanges and other component-fitted parts are machined, and these tapered, smooth surfaces facilitate frequent water clean-up. The unit is especially designed for easy disassembly to replace worn or damaged parts in the field.
The cover assembly incorporates a pressure gauge, air release lever, air bleeder valve, air pump and valves and petcocks used to perform both tests and calibrations according to ASTM C231.
To seal the cover to the base, there are 4 rugged stainless-steel clamps with quick locking action. The unit is unaffected by changes in barometric pressure. These clamps are resistant to corrosion from concrete, and they are easier to use and significantly less expensive to replace than older design clamps.
The new high-volume Super Pump requires fewer strokes to attain the test pressures. The check valve eliminates older design O-ring seal problems. The brass petcocks have ball valves for easy, durable operation.
The large 4-inch diameter sealed gauge with adjustable pointer and stainless-steel case is durable and easy to read and calibrate.
