DSS Module WSD 02 - Wet Stretch Dynamics Analyzer

The WSD02 Wet Stretch Dynamics Analyzer is a test device, which measures the wet expansion of paper under one-sided contact with water or other test liquids.

 


Benefits

fast contacting of the paper and liquid, important especially for high absorbent paper
real trial conditions by adjustable tightness
objective measuring method, free of subjective errors
high reproducibility of the results: ±0.05% of result
accuracy better than ± 0,1% abs. ± 5% of the analytical value in the area of 0 to 3% stretching
resolution approx. ± 0,013%
easy handling
integrated measurement of paper moistness and humidity, ambient temperature

Product description

The devices measures the dynamic of the of the change in dimension (stretching/shrinking) of paper, board and other materials as soon as it comes to an one-sided contact with the test liquid. Especially interesting is the measurement of décor paper under one-sided liquid contact (e.g. water, melamine resin and others). In addition, the change of the dimension of gypsum board, coating base paper, newsprint or offset printing papers can be measured under one-sided contact with water or inkjet ink.

The WSD02 replaces the classic methods to measure wet stretch behavior, which function under two-sided contact of the test liquid.

 

The measuring area:

  • Wet expansion to a maximum of 27%, measuring duration unlimited
  • Recording the expansion from the moment of liquid contact and displaying the results from approx. 100 ms after initial contact
