Speedy® 2000 Moisture Tester

Supports the following standards: ASTM D4944, AASHTO T217

The Series 2000 Speedy® moisture tester is a portable system for measuring the moisture content of a wide range of materials including soils, aggregates, dust and powders (and liquids). The system consists of a low pressure vessel fitted with a pressure gauge and an electronic scale and test accessories. Moisture measurements are made by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel. The reagent reacts chemically with water in the sample, producing acetylene gas that in turn increases the pressure within the vessel. The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content can be read directly from the calibrated pressure gauge. The Speedy has an accuracy of 0.5% on most materials and the gauge can be calibrated from 0-20% moisture, based on wet weight. Test speeds range from 45 seconds to 3 minutes depending on material. The tester is supplied complete with heavy-duty plastic carrying case, electronic balance (0-200g and battery operated, beaker, cleaning cloth, cap, washer,

Speedys do not include moisture testing reagent, see HAZARDOUS WARNING BELOW.

The 6g model is identical to the 20g version except for these two exceptions: it does not comply with ASTM or AASHTO specifications and does not include the steel pulverizing balls.


Danger of explosion/fire may result if Moisture Testing Reagent is allowed contact with moisture. Calcium carbide forms flammable acetylene gas when wet so it must be kept sealed and dry. Provide adequate ventilation and use away from sparks and flame. U.S. shipping regulations now require truck shipment for all quantities of calcium carbide. For this reason we no longer provide testing reagent (calcium carbide) with Speedy Moisture Testers. To purchase calcium carbide for use with Speedy testers, please order H-4966, which is a case of 24, 1lb (0.5kg) canisters. This item requires shipment by Truck.

International shipping regulations require separate purchase of reagent, which requires "dangerous goods" papers and packing. For this reason, Speedy Moisture Testers for International orders do not contain reagent, order separately.

Test Speed 45 sec. to 3 min., depending on material
Gauge Calibrated from 0-20% moisture based on wet weight
