HK BEKK Automatic Smoothness Tester

Product Introduction
The HK BEKK Automatic Smoothness Tester is an intelligent paper and paperboard testing instrument designed according to the internationally recognized Bekk smoothness testing principle.
Unlike traditional Bekk smoothness testers that use a manual lever and weight mechanism to apply pressure, the HK BEKK adopts a high-precision force sensor and stepper motor to automatically apply the standard test pressure. This innovative loading system significantly reduces the instrument's size and weight while improving pressure accuracy and measurement stability.
The instrument is designed for measuring the surface smoothness of paper and paperboard and is an ideal testing solution for the paper manufacturing, packaging, printing, quality inspection and scientific research industries.

• Stepper motor provides smooth and impact-free pressure application
• Standard test pressure accuracy up to 100 ± 0.5 kPa
• Eliminates sample impact caused by traditional weight-loading mechanisms
• More compact and lightweight than conventional lever-and-weight Bekk testers
• Stable pressure application independent of sample thickness changes
• Avoids pressure errors caused by spring fatigue
• Three measurement ranges for different smoothness levels
• Suitable for paper and paperboard quality inspection
• Simple operation and easy-to-understand test procedure

Working Principle
The HK BEKK Automatic Smoothness Tester measures paper surface smoothness according to the Bekk method.
During testing, a paper or paperboard specimen is placed between the test surfaces. The instrument uses a stepper motor and precision force sensor to automatically apply the specified test pressure.
After the test pressure is stabilized, a vacuum system creates a pressure difference between the test chamber and the sample surface. The instrument measures the time required for the pressure to change between specified vacuum levels.
The measured time, expressed in seconds, is used as the Bekk smoothness value. Generally, a longer measurement time indicates a smoother paper surface because the smoother surface provides better sealing and slower air leakage.
The instrument automatically controls the pressure loading and measurement process, reducing operator intervention and improving test consistency.

Innovative Pressure Loading System
A major advantage of the HK BEKK is its precision sensor-based pressure loading system.
Compared with traditional weight loading
Traditional Bekk instruments use a weight or lever-and-weight mechanism. When the weight is applied, the test specimen may experience a sudden mechanical impact, potentially affecting the sample and measurement result.
Compared with spring loading
Some automatic smoothness testers use spring-based pressure structures. Spring fatigue can cause pressure deviations over time. In addition, spring pressure may vary with specimen thickness.
HK BEKK Solution
The HK BEKK uses a stepper motor combined with a high-precision force sensor to provide controlled and stable pressure loading.
This design provides:
• Smooth pressure application
• No sudden impact on the specimen
• More accurate test pressure
• Reduced influence from sample thickness
• Improved long-term measurement stability

One-Button Automatic Testing
The HK BEKK is designed for simple operation.
Users do not need to manually adjust the test pressure or perform complicated setup procedures. After placing the specimen, the test can be initiated with one button.
The automatic system controls the pressure application and timing process, making the instrument particularly suitable for routine quality control and high-volume paper testing.
