Technical data and functions

Moisture Sensor

  • Moisture sensor for determination of the moisture content in mineral construction materials, wood and cardboard.
  • Indirect measurement of the moisture through the determination of the dielectric constant.
  • Capacity measurement through a high frequency electromagnetic field, which penetrates the material in a non-destructive way.

Wood moisture probe

  • Moisture sensor for determination of the moisture content in wood.
  • Indirect moisture measurement according to the principle of conductivity.
  • Determination of the moisture content in the material through the dependence of the electrical resistance on the moisture.

Capacitive sensor for applying onto the wood‘s surface

  • Moisture content sensor for comparative measurement of moisture in wood materials
  • The capacitive sensor with the measuring electronics is completely integrated in the damp-proof sensor housing. Plug-in ALMEMO® connecting cable
  • This device is designed for stationary installation and long-term monitoring e.g. of wooden parts of buildings, roof structures (with laminated beams).
  • It is also suitable for data logger operation in energy-saving sleep mode (intermittent mode).
  • The sensor housing is quick and easy to install on the wooden surface in question.
  • The material‘s moisture content is measured indirectly by determining its dielectric constant, which is moisture-dependent (but not temperature-dependent).
  • Its capacity is measured via a high-frequency electrical field which penetrates the wood without destroying it.
  • The ALMEMO® device acquires the material‘s moisture content based on the linearization curve stored in the ALMEMO® plug.
  • This measuring operation can be performed using any current ALMEMO® device (version 6 and above).
  • Conductivity measurement with measuring tips that can be screwed into the woodMoisture content sensor for comparative measurement of moisture in wood materials
  • Two hanger bolts are screwed into the wood surface and connected via measuring lines to the measuring electronics in the damp-proof sensor housing.
  • The sensor housing with the integrated temperature sensor is also fixed in position on the wood surface.
  • Plug-in ALMEMO® connecting cable
  • This device is designed for stationary installation and long-term monitoring e.g. of wooden parts of buildings, roof structures (with laminated beams).
  • Data logger operation in sleep mode (intermittent mode) is required in order to protect the wood from salinization or drying out.
  • The material‘s moisture content is measured indirectly by determining its electrical conductivity, which is moisture-dependent.
  • It is also temperature-dependent. However, the displayed moisture value is automatically temperature-compensated by means of an integrated temperature sensor.
  • The ALMEMO® device acquires the material‘s moisture content based on the linearization curve stored in the ALMEMO® plug.
  • This measuring operation can be performed using any current ALMEMO® device (version 6 and above).

Water Detection Probe

  • Water detection probe for instant detection of uncombined water.
  • Particularly suitable for construction applications, especially in locations that are difficult to check visually, e.g. at sealing joints, under cement floors etc.
  • Indirect moisture measurement according to the principle of conductivity.
  • Probe with two collets for easy electrode replacements.
  • Electrodes in three different designs for matching any required application.
