  • Page 30 9 Application Notes 9.1 Comparative Measurement or Reference Measurement With this type of measurement, almost all (set) building materials or mixed materials or mixed structures can be measured comparatively. It is important that these measurements are only carried out on the same materials or structures. A deliberately dry spot must be determined on the structure to be measured.
  • Page 31 (wt. %) in relation to the dry weight or also in CM-% (moisture determination according to the calcium carbide method). Depending on the type of GANN Hydromette used, this is done using programmed characteristic curves or independent conversion using tables.
  • Page 32 9.3 Notes on resistance-based Structural Moisture Measurement The GANN Hydromettes work according to the electrical resistance and conductivity measurement method that has been known for years. This process is based on the fact that electrical resistance is highly dependent on the amount of moisture in the material.
  • Page 33 The following applies in principle: - Generally, both electrode pins are to be applied to the same contiguous material to be measured. INFORMATION - Before drilling holes for probes or hammering electrode pins into walls, ceilings, floors, etc. make absolutely sure by suitable means that there are no electrical cables, water pipes or other supply lines in this location.
  • Page 34 9.4 Using the Hydromette BL E The Hydromette BL E is a multi-purpose measuring instrument for measuring structural moisture, wood moisture and temperature. The device utilises both the resistance measuring principle and the non-destructive capacitive measuring principle. This means that the device can be used in conjunction with different (active) electrodes depending on the measuring task.
  • Page 35 Measure: Press and hold the "M" button for longer than 2 seconds. A measuring process is carried out as long as the measurement button is pressed. After releasing the "M" button, the measuring process is interrupted and the "Hold" symbol is INFORMATION displayed.
  • Page 36 Please note: Any surface contaminants (e.g. formwork release oil) may cause errors. INFORMATION 9.4.3 M 6 Stick-in Electrode The two electrodes that are intended to measure set construction materials only are to be pushed into the material to be measured with approx.8 - 10 cm clearance. Where this is not possible because of the hardness of the material to be measured (floor screed, concrete etc.), holes of approx.
  • Page 37 For the M 6-150 probes with 3 mm Ø, which were specially developed for measuring through a spacer cross, a special carbide drill bit with a length of 160 mm and a diameter of 3 mm is required. This can be used to drill through the screed layer to the insulation. The distance between the probes should be approx.
  • Page 38 9.5 General Information on Wood Moisture Measurement The wood moisture in the GANN Hydromettes® is displayed in per cent by weight (wt.-%) in relation to absolutely dry wood (bone-dry). If wood is stored for extended periods in a given climate it assumes a moisture content corresponding to this climate, which is also termed equilibrium moisture or wood moisture equilibrium.
  • Page 39 9.6 Notes on resistance-based Measuring Wood Moisture The GANN Hydromettes works by measuring electrical resistance or conductivity, a principle which has been well-known for many years. This process is based on the fact that electrical resistance is highly dependent on the amount of moisture in the wood. The conductivity of oven-dried wood is very low, or the resistance is so high that no current worth mentioning can flow.
  • Page 40 > 20 °C they are too high. It is therefore necessary to correct the values obtained using an appropriate correction table. Various GANN Hydromettes® are already equipped with such temperature compensation, i.e. the wood temperature can be set directly on the measuring instrument and is automatically taken into account in the wood moisture display.
  • Page 41 using a spanner (WAF 12) or pliers. Loose electrode pins tend to break more easily and cause unstable measured values. If thicker wood is to be measured, the electrode pins can be replaced with a suitably longer version. With increasing tip length, however, increased danger of breakage or bending (particularly when pulling out) must be expected.
  • Page 42 Any wood particles adhering to the measuring surface must be regularly removed. If the elastic, plastic measurement sensors are damaged, they can be reordered (no. 31004316) and glued on using standard cyanate-based instant adhesive. 9.6.5 M 20-DS 16 and M 20-DS 16-i Conversion Kit The M 20-DS 16 conversion kit is used to measure the moisture content of wood up to 30 mm thick.

When first delivered, the ram-in electrode M 18 is supplied with 10 replacement pins of 40 and 60 mm length (not insulated).
  • Page 44 Therefore, no binding statements can be made in this regard. Of course, this problem does not only apply to capacitive measuring instruments from GANN, but is the physical basis for all moisture probes and sensors that work dielectric constant (DK), high- frequency or microwave basis.
