The Speedy Ashworth Calcium Carbide Moisture Meter (Speedy 2000 series, part numbers S-2000-C, S-2000-D, L-2000-C, L-2000-D and L-2000-G) is a portable instrument that measures the moisture content of materials including soils, aggregates, concrete, sand and powders. Moisture content drives decisions across many trades: too much water in freshly mixed concrete affects workability, strength and drying, while soil moisture outside the specified range compromises compacted earth embankments, so a fast field reading prevents costly rework.
The Speedy Ashworth Calcium Carbide Moisture Meter works on a calcium carbide reaction. A weighed sample is placed in a sealed vessel with a reagent and shaken; free moisture reacts to produce a gas, and the resulting pressure rise, proportional to the moisture present, is read directly from a calibrated pressure gauge. The Speedy Ashworth Calcium Carbide Moisture Meter is accurate and simple to use, robust and reliable, portable, and needs no external power source. Many materials can be measured over a wide moisture content range.
The range of the Speedy Ashworth Calcium Carbide Moisture Meter covers Standard and Large vessels. Standard models read 0 to 10% (S-2000-C, 0.10% divisions) or 0 to 20% (S-2000-D), with a maximum sample size of 10mm and gross weight around 5.5kg. Large models add a 0 to 50% range (L-2000-G), handle samples up to 20mm and weigh around 6kg. The Speedy Ashworth Calcium Carbide Moisture Meter conforms to ASSHTO, ASTM and DIN 18365 requirements, recognised standards in highway, civil engineering and building applications. Used by geotechnical engineers, building surveyors and restorers, and in mining, steel and foundry work. Supplied by BAMR, South Africa's authorised distributor.
Speedy Ashworth Calcium Carbide Moisture Meter
The New Speedy 2000 series are used throughout the world by a diverse range of industries to measure the content of materials including soils, aggregates, concrete, sand and powders.
- Accurate and simple to use
- Robust and reliable
- Portable and requires no external power source
- Versatile many materials can be measured over a wide moisture content range
When to use the Speedy Ashworth Moisture Meter
Use the Speedy 2000 when you need the moisture content of a bulk material such as soil, aggregate, concrete, sand or powder on site, not a surface reading. It uses the calcium carbide reaction and needs no external power, so it works in the field. The decision is choosing the right model for your moisture range and sample size.
- 1Works on bulk materialsIt measures moisture in soils, aggregates, concrete, sand and powders, covering the materials a site or batching lab actually handles.
- 2No external power neededIt is portable and requires no mains supply, so you can test at a borrow pit or batching plant away from any power source.
- 3Model matched to your rangeStandard and Large units cover 0-10%, 0-20% and 0-50% with set sample weights, so you pick the model that fits your material's moisture band.
- 4Meets AASHTO, ASTM and DINIt conforms to AASHTO, ASTM and DIN 18365, which matters where the test method is specified in highway or construction work.

Roads and Highways
Knowledge of the moisture content of soil is crucial throughout geotechnical engineering practice. Engineers use the Speedy for field control of compacted earth embankments and other structures and to measure the water content of soil to ensure it is within specified ranges Confidence in the test results is crucial, but the test equipment also has to be robust and simple to use.
The Speedy tester meets both requirements. It is recommended by the American Highway Authority and is approved by the American Society of State Highway Transportation Officials (ASSHTO) and by the American Society for Testing and Materials (ASTM)
Aggregates, Sand and Concrete
The moisture content of freshly mixed concrete affects the workability, blending, segregation, strength and drying rate of the finished product. The Speedy Tester is an ideal on-site quality control tool that enables the site manager to ensure best practice is being followed.
Moisture levels of aggregates and sand can be checked prior to use ensure that the correct amount of water is added when mixing with cement. The moisture content of ready-mix concrete can be checked on site arrival to ensure it is within specification.
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.
If the structure under investigation is contaminated with the conductive hygroscopic salts, moisture meter readings may not truly reflect the moisture condition. Ambiguity that may be associated with interpreting moisture meter readings in contaminated material are reduced by also measuring the actual moisture content of wall or floor samples with the Speedy Tester and by using a hygrometer to measure the materials equilibrium relative humidity (ERH) The Building Research Establishment Digest 245 details how a Speedy tester is used in the context of rising dampness diagnosis and treatment Solid Floors If moisture related floor failures are to be avoided, concrete floor slabs, cementitious screeds and anhydrite screeds have to be in a dry condition before decorative floor finished, including wood, vinyl and carpets are laid.
Many countries have adopted floor testing standards that use ERH measurement techniques whilst others use the DIN18365 standard which specifies moisture content measurement techniques. 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. .
