Gann Hydrometer HT 85 T

The HT 85 T is a multi-purpose measuring instrument designed to determine wood moisture, building material moisture, and temperature. Based on the electrical resistance measurement principle, it enables precise measurements of sawn timber (up to 180 mm thick), particleboard, veneers, wood chips, and similar bulk materials, as well as hardened building materials.

The "Hydromette" features wood temperature compensation, which automatically adjusts the measured value based on the temperature of the object being measured.
Its extensive wood moisture measurement range, combined with advanced temperature compensation, makes it ideal for use in drying kilns (e.g., for checking wood moisture immediately after the drying process) and at timber storage sites.

For building materials—such as screeds, mortar, plaster, concrete, brick, and various types of insulation—the device supports the connection of any electrodes that operate on the electrical resistance principle. This allows for the creation of accurate moisture profiles and depth-specific measurements within the materials.

In addition to air temperature, the device can measure surface temperatures and material temperatures (using Pt100 sensors).

It is particularly well-suited for interior contractors, parquet flooring installers, wood-processing companies, professionals in technical timber drying, construction firms, and architects.

Technical Data
  • Handheld moisture meter for quick individual and sequential measurements, featuring a high-quality measurement amplifier
  • Direct display of wood moisture content in % via a large LCD screen; resolution: 0.1%
  • 4-level wood species correction for over 300 types of wood
  • Automatic wood temperature compensation within a range of -10 to +90 °C
  • Precise measurement of air, surface, and material temperature using Pt100 sensors in a four-wire configuration
  • The device is supplied with a 9 V battery

Gann Hydromette BL E 2

The BL E is a multi-purpose measuring instrument for determining building moisture, wood moisture, and temperature.

For construction materials (e.g., screeds, mortar, plasters, concrete, brick, and various types of insulation), any electrode based on the electrical resistance measurement principle can be connected. This allows for the creation of precise moisture profiles and depth-specific measurements within the materials.
The device contains pre-stored calibration curves for various construction materials, enabling direct display of measured values ​​in terms of weight percentage (% by weight) or CM% (calcium carbide method equivalent).

Additionally, a capacitive building moisture electrode can be connected, allowing for non-destructive moisture testing in ceilings, walls, floors, and other construction materials.

Wood moisture is also measured using the electrical resistance principle, facilitating precise measurements of sawn timber (up to 180 mm thick), particleboard, and veneers. All common wood species can be measured.

In addition to surface temperatures, the device can also measure material temperatures (using Pt100 sensors).

This measuring instrument is particularly well-suited for painters, interior contractors, parquet flooring installers, wood-processing companies, construction firms, architects, and residential developers.

Technical Data
  • Handheld moisture meter for quick individual and sequential measurements, featuring a high-quality measurement amplifier
  • Self-illuminating OLED display
  • Intuitive, clearly structured menu system optimized for rapid navigation
  • Material selection via plain-text names
  • For resistance-based measurements: Direct display of moisture values ​​in % by weight (for wood) or in % by weight / CM-% (for building materials); resolution: 0.1%
  • For capacitive measurements: Scan mode (1–200 digits)
  • Wood moisture measurement: Includes characteristic curve groups 2 and 3, based on a 4-level wood species correction system
  • Precise measurement of surface and material temperature via Pt100 sensors
