SONO M1: Reliable measurement of moisture

Classical procedures for measuring moisture are sometimes cumbersome and inaccurate. The technology of Time Domain Reflectometry (TDR) remedies here. A technology SONO-M1 takes use of to determine material moisture. The handy two-rod probe measures moisture in sand, gravel, expanded clay spheres and other aggregates. The hand-held meter HD2 and SONO-DIS are appropriate as connection for SONO-M1.

With the help of electrical and magnetical field lines the penetration depth lasts into infinite within the material to measure. The effective, for the measurement relevant penetration depth of the SONO-M1 probes comprises double the rod length. The illustration shows the effectively recorded measuring volume with the green waves.
