This PFK paper moisture meter enables rapid and precise measurement of the absolute water content of piled up paper and solid cardboard stacks. The measurement is carried out non-destructively and directly on the stack. The moisture content is displayed on the large LCD screen within seconds.
The PFK is ideal for quality control, as for example at the receipt of goods and during the paper production process. In both cases, it is absolutely essential to achieve consistent quality.
The measured value is saved in one of the 10,000 memory locations. Thus, no measured value is lost and documentation is also made possible so that the user obtains traceable and reliable measurement information. This battery operated moisture meter is for easy one handed use.
The PFK paper moisture meter is supplied as a complete set, including:

Selection of the correct curve
Due to the countless paper types, there are no standard curves.
For the Checkline PFK paper moisture meter, the density of the paper stock or paper roll determines the different curves.
The above overview of the curves contains suggestions for paper types and paper densities [kg / m³].
To achieve an exact measurement result, a one-time comparative measurement is required with your online moisture measurement or by performing the standardized oven method (DIN 287).
1. Measure your paper (on the roll or on the stack) with the available curves which give a realistic value and note the different measurement results with the corresponding characteristic curve names.
2. Now record the actual water content of your online moisture measurement or carry out a determination of the reference water content according to EN ISO 287.
3. Now compare the recorded measurement results of the different curves with the actual water content according to the reference measurement. Now you can select/determine the curve that is most accurate with the reference measurement.
