|The DM4A Moisture Meter is a universal moisture meter for measuring moisture content in wood, building materials, paper, cardboard and numerous other materials. Non destructive – in seconds – only push and read.
Conforms to : DIN EN.50081 & 2(EC Rated)
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:
The DM4A Moisture Meter can be used in accordance with:

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)
