Moisture Measurement for aggregates and sand using

Ability to set high or low moisture levels alarms Modern plants can weigh aggregates with an accuracy of up to ± 0.5%. If the amount of moisture in a batch of sand or aggregates varies from between 2% to 10% then this will affect the accuracy and proportions of the weighed materials since water is effectively being weighed and not dry materials.
