Calibration method of direct reading concrete air content meter Instrument calibration:

When the instrument is calibrated, the operator's visual height must be vertical to the instrument dial and away from the dial 40Cm Any careless operation will affect the accuracy of calibration results.

(1) Vessel calibration

one Measuring the water weight of full measuring bowl by volume correction W The weighing accuracy is water weight 0.1% Weigh the bowl and glass plate with a bench scale. Fill the measuring bowl with water and push the glass plate along the top of the measuring bowl to drive away the bubbles. Make the bowl full of water without bubbles under the glass plate. This volume is the weight of the water in the bowl, which is the weight of the water in the bowl, which is the dry weight of the water in the bowl.

?????? 2 Calibration of calibration vessel

Place the calibration vessel on the horizontal platform and inject water inward until the water surface reaches the bottom of the vertical gap under the triangular weir (the influence of water surface tension on the concave surface should be considered during observation). Accurately measure and correct the water weight of the container U , weighing ????? ? The accuracy is water weight 0.1%

Calibration method of direct reading concrete air content meter Technical parameters:

one The maximum aggregate size of concrete shall not be greater than 40mm

two Maximum gas content measured value 10%

three The size and volume of concrete measuring bowl 7L The ratio of inner diameter to height is one one

four Display instrument: pressure range 0.1MPa , division value 0.005MPa
