The universal moisture tester can be used for soils, sand and fine aggregates.

The operating principle is identical for all models: the sample is introduced into the bottle with the reagent and the water in the sample reacts with calcium carbide and produces a gas, the pressure of which is indicated on the manometer and easily converted into the percentage of moisture.

The models can determine moisture contents of 2% or under on samples up to 100g in mass, the long bottle version can determine up to 20% on 20g samples, while the Speedy models are suitable for determinations of up to 20% on 6-20g of sample.
