    5.3.3 Compensation Temperature Press Down button twice Measuring menu The Hydromette has an automatic compensation of the measured value depending on the adjustable material temperature. This measured value compensation is always carried out with the temperature displayed in the measuring mode. The instrument is supplied as standard with a compensation temperature of 20 °C as the factory setting.
  • Page 21 Compensation temperature via external temperature sensor No further settings need to be made in order to use this function. The ET 10 BL Pt100 temperature sensor must be connected to the measuring device via the 3.5 mm jack receptacle. Ensure that the octagonal plug is firmly seated. The measuring instrument now automatically recognises the connected sensor.

    7 Application Notes 7.1 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 27: General Information On Wood Moisture Measurement

    7.2 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 28: Notes On Resistance-Based Measuring Wood Moisture

    7.3 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.

    1 % wood moisture for every 10 °C deviation from 20 °C, provided the wood is dry. In addition, the GANN Hydromettes® have a wood temperature compensation table in the appendix of the operating instructions.

  • Page 30: Using The Hydromette Bl Ht 70

    7.4 Using the Hydromette BL HT 70 When measuring wood moisture, the two measuring tips of the Hydromette must be pushed / hammered into the wood to be measured at right angles to the fibre direction. When removing them, light prying movements can be used at right angles to the grain to loosen the tips. Please refer also to the notes on wood moisture measurement in Sections and 7.3.

    7.4.1 M 20 Drive-in Electrode The M 20 drive-in electrode is made of impact-resistant plastic and is suitable for measuring wood thicknesses of up to 50 mm. When the drive-in electrode M 20 is first delivered, 10 replacement tips of 16 and 23 mm length are included in the delivery. The two electrode pins of the drive-in electrode must be pressed or hammered into the wood to be measured at right angles to the fibre direction.

    7.4.3 M 20-OF 15 Surface Measuring Caps The surface measuring cap pair M 20-OF 15 is used in conjunction with the M 20 electrode for resistance-based measurement of moisture on surfaces without damaging the material being measured. In the area of wood moisture, it can be used to measure workpieces that have already been processed or to measure veneers or multi-layer parquet / multi-layer planks.

  • Page 33: M 19 Stick-In Electrode

    7.4.5 M 19 Stick-in Electrode The stick-in electrode M 19 is made of impact-resistant plastic and is suitable for measuring finished thermal insulation composite systems (e.g. wood fibre insulation materials). The initial delivery of the stick-in electrode M 19 includes 10 Teflon-insulated electrode pins, each 60 mm long. To change the electrode pins, the coupling nut must be unscrewed.
  • Page 34 Please note that: - In order to determine any increased core moisture, the electrode pins must be driven in approx. 1/3 of the entire wood thickness. - Particularly in the case of moisture ingress from outside, e.g. rain or condensation, only the increased surface moisture is measured, regardless of INFORMATION the penetration depth.
