Using SONO-M1 probes

Introduction

Time-domain reflectometry (TDR) is a widely used technique to determine material moisture. In the
past, efforts to measure the moisture content were complex and laborious, and the results obtained
were not precise. Since the development of TRIME-TDR technology, there is almost no reason for busi-
nesses to rely on inaccurate and complicated technology to measure moisture.

Measuring volume of SONO-M1 probes

In theory, the electric and magnetic field lines penetrate the material to be measured to an infinite
depth. However, the SONO-M1 probes' effective penetration depth, which is relevant for measure-
ment, is approximately twice the distance between the rods. The effective measuring volume cap-
tured with this probe is illustrated in the graphic below (green waves).
