Location

Since moisture measurement using the Moisture Analyzer is based on a highprecision weighing procedure, accuracy and repeatability are closely linked to the instrument's location. To ensure that your Moisture Analyzer works under the best conditions, please observe the following guidelines:

Weighing Bench

  • Aufstellung HR83.jpgStable (lab bench, Laborkorpus, stone bench)
    Your weighing bench should not sag when work is carried out on it and should transfer as few vibrations as possible.
  • Antimagnetic (no steel plate)
  • Wall or floor installation
    The bench should either stand on the floor or be secured to the wall, but not both at the same time otherwise vibrations from both sides will be transferred.

The weighing bench must be stable enough so that the weight display does not change when you lean on the table or step up to the workstation.

Tip: You can use the vibration adapter to adapt your instrument to the ambient conditions at the place of installation. For example, set the vibration adapter to high for use under rough conditions

Guide to Moisture Analysis

Work room

  • Aufstellung Raum2.jpgVibration-free
  • Free from drafts
  • Wall or floor installation
    The bench should either stand on the floor or be secured to the wall, but not both at the same time otherwise vibrations from both sides will be transferred.

Place the bench in a corner of the room. These are the most vibration-free areas of a building.

Free space

  • Ensure sufficient free space around the instrument to prevent a build-up of heat and overheating (approx. 1m of free space above the Moisture Analyzer).
  • Ensure sufficient distance from combustible materials.
  • Ensure sufficient space from other sensitive measuring devices.

Temperature

  • Temperatur2.jpgKeep the room temperature as constant as possible. Weighing results depend on temperature!
  • Do not place the Moisture Analyzer near heaters or windows (thermal radiation).

Atmospheric humidity

  • Luftfeuchte.jpgIdeally, the relative atmospheric humidity (% RH) should be between 45 and 60%. Balances should never be operated above or below the measuring range of 20 to 80% RH.



Some samples are very hygroscopic, i.e. they take moisture out of the surrounding air. You should therefore try to keep the relative atmospheric humidity as constant as possible to ensure good repeatability of results.

Light

  • Licht.jpgIf possible, place the Moisture Analyzer on a window-free wall. Direct sunlight (= heat) will influence the weighing result.



Note: Active cooling protects the weighing cell from the heat produced by the halogen radiator. However, the weighing cell is not protected from thermal radiation at the sides and direct sunlight can therefore influence the weighing result.

Air flow

  • Luft.jpgDo not place the Moisture Analyzer in the air flow of air conditioners or devices with ventilators, such as computers or large laboratory devices.
  • Place the Moisture Analyzer at a sufficient distance from radiators. As well as the effects of temperature radiation, these also have strong and interfering air flows.
  • Do not place the instrument next to a door.
  • Avoid places with high traffic (drafts).
  • If possible, keep the windows closed to prevent drafts.
