The DOT600 roadbed water content meters, available from Campbell Scientific , are used in construction applications to measure volumetric and gravimetric water content of samples of earthen material in roadbeds and foundations.

Portability, along with quick and accurate measurements, makes the DOT600 roadbed water content meters a valuable tool for evaluating roadbed material both at the construction site and in the soil test lab. Samples collected from laboratory or field sites are compacted to a chosen pressure (15psi to 45psi), then the water content is measured using dielectric permittivity sensitive methods.

A separate scale and magnetic linear sensors measure the sample volume, which allows calculation of bulk density and conversion of the measured volumetric water content to gravimetric water content. Measurement results are written to a data table for permanent record. All measurements are controlled by a Campbell Scientific CR850 data logger. The CR850 includes an eight line display and keypad for interface.
