Product Description

Speedy Ashworth Calcium Carbide Moisture Meter

Knowledge of the moisture content of soils and construction materials is of great importance to engineers involved with the construction of roads, bridges and other civil structures. Throughout the world, the Speedy Ashworth Calcium Carbide Moisture Meter is used on construction sites to establish the percent moisture content (%MC) of these materials before the actual construction work commences.

The Speedy Ashworth Calcium Carbide Moisture Meter is a portable-sampling instrument used to determine the moisture content of a broad range of materials. It comprises a hand held vessel incorporating a pressure gauge and a precision balance, mounted in an integral carry case.


This classically simple product gives reliable and accurate results in very demanding environments. A small sample of the material to be tested is weighed on the balance and then placed in the vessel. A measure of reagent – calcium carbide – is then added and the vessel sealed. The reagent reacts with the free moisture in the sample to produce acetylene gas, resulting in an increase in pressure within the vessel. The % moisture content of the sample is then read directly from the calibrated pressure gauge.Building Restoration and Refurbishment

Building surveyors involved with diagnosing the cause of dampness in buildings use the Speedy tester to determine the moisture level in walls and floors. The Speedy complements moisture meters and hygrometers that are also used for diagnosis.

Moisture content in Solid Floors

If moisture related floor failures are to be avoided, concrete slabs, cementitious screeds and anhydrite screeds have to be in a dry condition before decorative floors finishes including wood, vinyl and carpet are laid. The Speedy tester is used to measure the moisture content of a sample of material removed from the floor before the decorative finish is laid.

The Speedy 2000 series of moisture testers combines time proven dependability of the pressure test procedure with the convenience of an electronic balance.

  • Moisture measurements are obtained by following a simple test procedure:
  • Prepare and weigh the material sample using the electronic balance
  • Place the sample in the Speedy vessel
  • Add the reagent to the recess in the Speedy cap and seal the vessel
  • Shake the Speedy to mix the reagent with the sample
  • Read the moisture content directly from the integral gauge
