6 Determining moisture levels

   

■

49

Solids:

• Distribute powder samples evenly on the weighing pan.
• Make course samples smaller using a mortar or grinder. Do not 

expose the sample to any heat while you are grinding it as this will 

lead to a loss of moisture.

Liquids:

• You are advised to use a fiber glass filter for liquids, pastes or slurry 

samples. The fiber glass filter offers the following advantages:

– even distribution on account of the capillary effect

– no formation of drops

– quick evaporation due to the larger surface

6.2.1 Preventing samples being encrusted

In order to avoid the sample becoming encrusted, solvent can also be 

added to the sample after the measurement has started. The solvent 

added has no bearing on the final result of the measurement.
• Start the measurement, automatically or by pressing the «

START/

STOP

» key.

• The moisture analyser hood can be opened again within 5 seconds 

of the start. During this time, the words "START DRYING" are 

displayed in the info line of the display. 

• After opening the sample chamber, you can add additional solvent 

at any time until the hood is closed. Once the moisture analyser 

hood is closed, the measurement is continued. "START COVER 

CLOSE" appears in the info line in the display. If you press the 

«

START/STOP

» key, the measurement is interrupted.
