Speedy Moisture Testers
Standard Speedy Moisture Testers BS : 812 / ASTM : D4944 / AASHTO : T217

Designed for the most demanding on-site conditions the new waterproof and durable case offers high levels of protection. The Speedy Moisture tester comprises electronic balance beaker, 2 steel balls, cleaning brush and Calcium carbide.

The Test

Used to weigh a sample before placing it in the Speedy Moisture Tester content of the sample is read directly from the calibrated pressure gauge The determination of moisture content of soils, sand and fine aggregates. The procedure involves the reaction between water and calcium carbide which when mixed together give off a gas. The amount of gas is directly proportional to the amount of water present in the sample and results in percentage are taken from a pressure gauge.

Digital point load tester (Rock strength index)
STANDARD: ASTM D5731

Used to determine the strength values of a rock specimen both in the field and in the laboratory.It consists of a load frame for applying loads up to 55 KN, on which a manual hydraulic jack is mounted. The instrument accepts core specimens up to 4” (101,6 mm) diameter which are loaded by two cone shaped points. A graduated scale indicates the distance between the conical points. The applied load is measured by a pres¬sure transducer with a digital display unit range 0-56kN, 65.000 divi¬sions, 0,001 kN resolution, accuracy: ± 1%. The strength index (IS) is got by the formula P : D2 where P is the strength and D the space between the two conical points.
