Moisture measurements of wood and fiberglass hulls with portable meters

Moisture measurement on wooden and fiberglass hulls

Detection and localization of osmosis phenomena on boats or parts exposed to high humidity

Verification of the state of drying of products before painting or aesthetic treatments

The Tramex Skipper Plus, non-destructive moisture meter, provides a complete and safe method for detecting excess humidity in fiberglass and wooden hulls. The Skipper Plus is a pocket hygrometer, designed to locate humidity in the hulls and accessories of the boat.

Three scales for humidity detection in GRP and hardwood for salt and fresh water.

  • Wide range of wood readings from 5% to 30% on a hardwood scale and from 0 to 100 on a comparative scale for fiberglass and other materials.
  • Identifies the presence of osmosis in fiberglass hulls.
  • Confirm if the wooden boats are dry enough for painting or varnishing.
  • Track leaks on decks and bulkheads.
  • The "Hold" function facilitates the recording of readings.
  • Soft rubber electrodes provide direct contact without scratching.
  • Audio warning tone for high humidity can be activated or deactivated.
  • Battery operated (included)

Application

Measure the presence of osmosis phenomena on fiberglass boats.

Locate any parts that have a more pronounced exposure to osmosis than other areas.

Check the state of conservation of wooden boats or the degree of humidity before aesthetic treatments, painting or impregnation.

Solution

Skipper Plus is based on the principle of measuring non-destructive impedance. Coplanar electrodes, mounted on the base of the instrument, transmit low frequency signals in the tested material and measure the variation of impedance caused by the presence of humidity. This reading is indicated on the instrument as a reading of the moisture content.

  • Three ranges for moisture detection in fiberglass and hardwood for fresh and salt water.
  • Wide range of wood readings from 5% to 30% on the hardwood scale and from 0 to 100 on a comparative scale for GRP and other materials
  • Identifies the presence of osmosis in fiberglass hulls.
  • Confirm if the wooden boats are dry enough for painting or varnishing.
  • Track leaks on deck and bulkheads.
  • The "Hold" function facilitates the recording of readings.
  • The soft rubber electrodes come into direct contact without scratching.
  • High humidity acoustic warning tone that can be turned on or off.
  • Battery operated (included)

The Skipper Plus moisture meter is used for:

  • Timely detection before the appearance of osmotic bubbles.
  • Identification of the affected area.
  • Hull monitoring during dehumidification and repair phases.
  • Checking the drying of the abraded areas before recoating.

To obtain lasting finishes and resistance of hulls and wooden components, it is essential to ensure that they are well maintained and that they do not contain excess humidity.

Excess humidity can create phenomena of structural and aesthetic deterioration, both on wooden and fiberglass hulls or special composite materials.

Analog data output, RS232, RS422, Profinet, Profibus, Ethernet.

The LASER LDM family of distance meters consists of a series of optoelectronic distance measuring devices for industrial applications with analogue interface (from 4 mA to 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422).

The LDM series LASER distance meters are used for the precise measurement of distances from a few meters to three kilometers. The distance measurement represents aconsolidated application for laser technology.

These optical sensors use LASER (pulse or modulated) light to measure distances, heights, lengths, levels and positions in a non-contact process. To achieve this, all components work together in a perfectly coordinated overall system.

This system consists of a laser emitter, optical transmitters and receivers, photosensitive diodes and sophisticated electronics and algorithms for time measurement or phase measurement. We use different optoelectronic principles for our measuring devices, such as time of flight, phase comparison and back-mixing LASER pulse. These methods allow singles accurate measurements to the millimeter, and measuring ranges up to several hundred meters. Using our LASER distance meters is possible measure on natural surfaces or on special reflectors obtaining fast and precise results.

LASER distance meters work using visible or invisible optical radiation and are classified in accordance with current regulations in class 1 or 2 (safe classes for operation even without protective glasses).

The compact construction allows easy installation of the LASER distance meter even where space is limited or in industrial applications. All devices offer standard interfaces, analog or digital data output and parameterizable switching outputs. The family of LASER LDM distance meters is particularly used for applications in the industrial sector with analog (4 - 20 mA) or digital (Ethernet, Profinet, Profibus, RS232, RS422, SSI).
