AquaControl  controls the water dosing in the mixer to give consistent moisture or slump in the final product.
AquaMix 2270D is a moisture sensor for use in mixers used in concrete production and other applications where there is severe abrasion.

AquaMix 2270D measures moisture in concrete mixers.  It communicates with a control system which corrects the water in the mixer to give constant yield, colour/texture and workability, as well as strength and durability.  For more general information on moisture measurement, see our range of Moisture Sensors.

AquaMix 2270D Specification

Measuring range:0 – 20% moisture, calibrated for 'average concrete'. Other ranges and materials on request.
