Concrete Air Meter Calibrators

Pressure Meter Calibrators offer quick, on-the-spot checks for accuracy of any Type B concrete air meter, including the Gilson Concrete Air Meter and Super Air Meter. With a calibrator in the water-filled base of a 0.25ft³ air meter, the gauge should indicate 5% air. Two calibrators are used in the meter for a 10% air reading.
