INTRODUCTION:
With the moisture measuring instrument MC-300WS, Exotek AB has introduced an hand-held moisture
measuring unit, incorporating electronic circuitry perfected over years of development and practical
application.
The wood moisture measuring instrument MC-300WS works on high frequency according to the contact
measurement process, thus a damage of the material to be measured is excluded.
Due to the approval contact measurement procedure, a quick determination of the moisture in timber is
given.
Since it is used individually and is designed to full requirements economically, this unit satisfy in every
respect the demands made on a modern precision measuring apparatus.
Reliability, durability and a high standard of accuracy are assured by ultra-modern, completely dependable
digital analogue components built to cope with the stress of uncompromising everyday use.
The setting of the wood-groups and of the building material combined with the automatic 0-correction,
allow exact measurements on all European and exotic timbers.
The MC-300WS moisture measuring device is equipped with an international standardized 9-Volt alkali
block-battery, which can be obtained anywhere.
SWITCH-ON:
By pressing the left push-button, the unit is switched on.
SWITCH-OFF:
By pressing and holding the left push-button (after the unit is on and the values have been displayed),
the unit is switched off after ca. 3 sec.
or: If the unit remains to be switched on after measurements have been taken, it’s being switched off
automatically after 2 minutes, if it is not in use.
SELECTION OF WOOD GROUPS:
After the unit has been switched on, the previous selected group for wood is indicated on the Display (H2
- H10) Each time the left push-button is being pressed again (during the valid group is shown), the unit
selects the next higher group in steps of 1.
The indicated wood group is equivalent to the density range of the timber. For selection of wood group
see Wood Group Selection Table (page 5 – 14)
MEASURING PROCEDURE:
After selecting the appropriate wood-group, releasing the left push-button, the unit must be hold up
in the air. The unit is „ready for use“ after about 3 sec. On the display will appear “00.0 “ and now
measurements can be taken by placing the instrument at on the material.
After approx. 2 sec. a correct and constant measuring value is being achieved, indicated by a minus ”-“
sign in front of the value.
THIN MATERIALS:
For single materials, thinner than 5 mm, the volume is too small for accurate measuring values, but it is
possible to make comparing measurements to determine for example too wet areas.
To obtain exact measuring results, we recommend measurements in a pile, but take care in getting a
thickness of 5 mm minimum, as well as having no air-spaces between the single sheets.
For single, thin materials there is the possibility of a special calibration of the meter. Therefore we have to

do comparing measurements via the DARR-method. The calibration then is done at our company, simply
be changing the program, with analysing the corresponding comparing measurements. On request we
do these tests for you.
BASE:
With material thickness < 25 mm you absolutely have to take care of the right base. Generally avoid a
metal base. The best results are taken, if the material to be measured is hold up in the air. You also can
use polystyrene with at least a thickness of 50 mm.
HOLD-FUNCTION:
Please follow the instructions about the SWITCH-ON and the SELECTION of wood-groups
By shortly pressing the right push-button “HOLD“ additionally, the measured value is being frozen. In front
of the measured value appears the sign ” : “.Now it’s possible to take measurements at places where
the values can’t be read directly. On making new measurements the indication of the value automatically
re-starts.
VOLTAGE:
The unit is equipped with an international standardized 9 Volt alkali block battery. In case of low voltage,
an arrow ”←“ appears at the left upper side of the display. Now the battery has to be exchanged, to
ensure further, correct measuring results.
