The density of asphalt pavement is directly proportional to the dielectric constant of the measured material.The gtj-2701 USES an innovative, spiral-shaped magnetic field detector to test the dielectric constant in the presence of a magnetic field generated by the sensor plate. The electronic components of the gtj-2701 convert the field signal into a material density reading displayed on the screen.Once the instrument is calibrated, the density can be read at once.
