ModularLine PPS Print Surf Rauhigkeitsprüfgerät

For Measuring roughness according to the Print Surf method. The print surf method is a technique for determining the surface roughness of coated or calendered papers. It is also used on newsprint paper. The ModularLine PPS roughness measurement device operates, as with other techniques, using the air leak method. It has a very precisely manufactured measurement head as well as outstanding measurement technology. The throughflow is determined using two sensors, guaranteeing reliable and highly accurate measurement results across the entire area. The configuration with two measurement heads allows the upper and lower surface of the sample to be measured at the same time.

Test Description

The sample is pressed against the measurement head at a defined pressure of 490, 980 or 1960 kPa. A pressure regulation system creates a pressure differential at the measuring mechanism of 19.6 kPa. The flow through is determined using the integrated sensors. The results are then calculated according to the formula required by the standard. Measurement areas smaller than 1 μ are automatically measured with an additional sensor for limited throughflow. This leads to a significant increase in accuracy and stability of the results, even in small areas.
