How to use Aqua-Boy Meters

Aqua-Boy Operating Instructions

Read only the scale relating to your product
(the one beneath the 1 - 100 scale).

  1. Having connected the electrode to the meter, bring it into firm contact with the product to be measured.
  2. Press the white measuring button and read the result directly on the meter scale.
  3. Release with the button to finish the operation.
  1. Electrode jack
  2. White measuring button
  3. Red Battery Test
  4. Battery compartment in back

Some of our moisture meters are equipped with an additional universal centesimal scale for universal measurements on materials other than listed.

Our construction BM1 construction moisture meter is equipped with an additional colour scale divided into three areas: green = dry, white = normal, red = wet.

Inserting the interchangeable electrode Heads and connecting the cable.

  • Insert electrode head ‘2’ selected into holder ‘3’ and screw down retaining ring ‘1’.
  • Plug one end of cable ‘4’ into jack of holder ‘3’ until it snaps into place.
  • Introduce the second plug of the cable‘4’ into the jack of the moisture meter .

Connecting the Hammer Electrode

Insert one end of the universal measuring cable into the jack in the hammer electrode until it snaps into place.

Dependent on which meter you have there are different scales. The 1-100 scale is centesimal, not a percentage scale. This scale is only an indication – not in % but 1 - 100.

THE “100” Centesimal Scale

All our moisture meters are equipped with dials graduated and calibrated for specific materials and applications and indicating the moisture content directly in per cent.

Many of our moisture meters have a second centesimal scale in addition to the scale graduated in per cent. The readings obtained on the linear centesimal scale represent neutral working values and no moisture percentage figures. The centesimal scale readings must be converted into per cent moisture content by means of conversion tables that are available for the various types of moisture meters and materials.

The universal centesimal scale also makes it possible to measure materials other than those for which the scales graduated in per cent are intended. If used on other materials, the scales graduated for specific products would not indicate the true moisture content in per cent.

The textile moisture meter, for instance, which is equipped with three scales graduated in per cent. for wool, rayon and cotton in addition to the centesimal scale, permits all usual types of yarns and yarn mixtures to be measured by means of the universal centesimal scale in conjunction with special conversion tables. This applies similarly to other types of moisture meters and materials.

The universal centesimal scale also permits materials to be measured whose moisture content is not identical with the specific percentage scale, provided the moisture meter has a wide enough measuring range. For this, the desired moisture scale must be determined by comparing the meter readings with drying oven tests, i.e. by confronting the centesimal scale readings with parallel oven test figures in a graph that is to serve as the basis for the moisture curve. In many cases it will be sufficient to establish empirical values on the universal centesimal scale for the purpose of comparative moisture testing and supervision.
