The DM4A Moisture Meter is a universal moisture meter for measuring moisture content in wood, building materials, paper, cardboard and numerous other materials. This non destructive moisture meter gives you digital readings in seconds. Also capable of measuring moisture in caravans, mobile homes, trailers, or at plastic boats (osmose problematic). The DM4A can be used in accordance with DIN EN.50081 & 2 (EC Rated). Features: The pocket size, robust, hand held, electronic moisture meter is suitable for a quick determination of the moisture. The materials are merely touched and the % moisture appears on the display, (approximately one reading every 2 seconds). The depth of penetration of the measuring field into the material is approximately 30mm, thereby the moisture in low lying layers is obtained as well. The average moisture % is shown. Time consuming preparations (i.e drilling holes & waiting for heat to dissipate) are no longer required. Supplied in foam lined pouch with instructions. Other features include:
  • material group setting by means of a membrane-type keypad.
  • the adjusted material group can always be seen in the display.
  • microprocessor controlled measuring with automatic zero point correction.
  • up to 10 different customer specific linearisation curves, with up to 8 free programmable linearisation points can be implemented.
  • storage for 100 moisture values.
  • automatic calculation of maximum, average and minimum value.
  • fixed linearisation curves for a lot of common materials are already stored and can be selected.
  • the instrument’s calibration can be checked with the optional calibration modules PE05 and PE30.
Optional Extras
  • Software DMI-Controller which includes RS232 serial interface cable for connecting to a PC.
  • different settings can be chosen and measured and stored. These values can then be transferred to the PC for analysis and storing on a disc.
  • the instrument can be made with an aluminum casing for better protection against mechanical and electrostatic influence.

Measuring Principle (Capacitive) : The micro-processor controlled moisture meter measures the moisture indirectly in determining the dielectric constant. Therefore a capacitive measurement is done over a high frequency, electronic field, which passes through the material without damaging it. Neutral Point : The neutral point (np) is continuously monitored and is automatically corrected by the micro- processor. Measuring Process : After pressing the “on” button and holding the meter in the air, to obtain the automatic neutral point, the 3 spring steel sensors must be firmly pressed onto the material to be tested. The reading is retained until the next reading is made. Selecting material setting : Press “mat” – key, choose material with arrow keys (up or down) and set it by pressing the “ok” pad (see list below)
