ST-01 Smoothness Tester is a high-precision equipment for measuring the surface smoothness of paper and board according to the Bekk Method. It is used to determine the smoothness of paper and board.
Smoothness is a metric used to evaluate the degree of unevenness on the surfaces of a paper. It indicates the flatness and smoothness of each paper's surface. In general, smoothness refers to the time required for air to flow through a certain amount between the sample surface and an annular surface under specific contact conditions and a certain pressure difference, measured in seconds (s). The longer the time, the better the smoothness of the paper, and the higher the smoothness rating. Generally, the higher the paper's smoothness, the better the print quality will be. Therefore, achieving satisfactory print quality requires smoothness as a necessary condition.
Bekk smoothness:
Time in seconds which, un-der a defined pressure differential, is required to draw a definite quantity of air at atmospheric pressure be-tween the surface of the test piece and a ring-shaped plane surface, under specified conditions of contact.
Principle
Subjection of a test piece of paper or board placed on a glass plate to a specified pressure and creation of a partial vacuum to draw atmospheric air across the contact surface. Measurement of the time required for a specified change in vacuum.
One-button testing, no need to set pressure or other steps, easy to use.
The use of stepper motor and high-precision load sensor makes the paper pressing smooth and impact-free, and the paper pressing force is more precise (accuracy 100±0.5kPa).
Note: Directly using a weight or a weight lever mechanism will impact the sample, causing damage to the sample. Some automatic smoothness meters adopt spring pressure structure, which may cause pressure inaccuracy due to spring fatigue. In addition, the pressure will vary with the thickness of the sample.
The CPU uses a 32-bit ARM processor, which improves the processing speed of the instrument and makes the calculation data more accurate and rapid.
A large 7-inch color touch screen
Precise airflow detection technology, and the instrument automatically identifies the required range for the tested sample and automatically switches the range. It accurately controls the venting speed according to different samples.
Embedded thermal micro printer.
Imported oil-free vacuum pumps that require no oil or maintenance for life.
