    Air pockets around the tube wall can reduce the measured moisture reading. Where saturated soils are involved, water-filled air pockets will result in an exaggerated reading. IMKO supplies drilling equipment for an optimal preparation of the installation point, avoiding air gaps around the tube and compaction of soil.

Some materials, especially very clayey soils and soils with high organic contents, can afford ma- terial specific calibrations due to their different dielectric behaviour. A limiting factor in TDR measuring is the electrical conductivity.

The probe can be installed up to 50 meter depth with an extremely rugged and rollable crane cable. The T3/IPH50 has the same length as the T3/IPH44 tube access probe, but the diameter is big- ger, so that the probe can be installed in standard plastic installation tubes.

  • Page 26: Basic Calibration With The Calibration Set

    TRIME sensor. Every TRIME-PICO IPH sensor must be calibrated before it can supply proper measure- ment results. Basic calibration is carried out by IMKO in the factory prior to shipment. 11.2 What are the benefits of the calibration set for the user? With the calibration set you can easily carry out basic calibration of your TRIME sensor yourself.

  • Page 27: Basic Calibration Procedure

    ® 2017-05-30 TRIME -PICO IPH Version 2_0 Fill up one bucket until the rods of the probe can be immersed completely. To obtain a consistent density, knock the bucket on the ground several times. The density of the glass beads increases with frequent insertion of probes. Therefore the glass beads should be poured out into another bucket and poured back to achieve the original density.
