Speedy® 2000 Moisture Tester (20g)

The Speedy 2000 moisture tester provides a portable method of estimating moisture content in soils, aggregates, powders and other compatible materials without requiring an oven at the jobsite. A weighed sample is sealed in a pressure vessel with calcium carbide reagent, which reacts with water to produce a pressure change indicated on the calibrated gauge. This chemical reaction enables results in minutes and makes the system useful for field decisions where waiting for conventional drying would delay work. The package includes weighing and handling accessories in a protective carrying case, but the calcium carbide reagent must be purchased separately.

Key Features

• Provides rapid moisture measurements for materials-testing applications; verify whether the governing project specification permits calcium-carbide testing rather than oven drying under ASTM D2216 or AASHTO T 265.
• Delivers results in approximately 45 seconds to three minutes, helping field crews make timely decisions about moisture-sensitive work.
• Uses a sealed pressure-vessel method that avoids dependence on a laboratory oven at the sampling location.
• Includes a portable electronic balance and handling accessories so technicians can prepare and measure samples in the field.
• A calibrated pressure gauge allows moisture content to be read directly after the reagent reaction.
• The protective carrying case helps organize the instrument and accessories for transport between jobsites.

Included Items

Pressure vessel with moisture gauge, electronic 0–200g balance, beaker, cleaning cloth, cap, washer and heavy-duty carrying case. Calcium carbide reagent is not included.

Lab Manager's Tip

Carry the correct reagent and follow the instrument's safety instructions for the acetylene-producing reaction; keep ignition sources away. Because ASTM D2216 and AASHTO T 265 are oven-drying methods, verify that the governing agency permits this rapid method and establish material-specific correlations where necessary.
