Product Description

Product Overview

The fully automatic smoothness tester is a specialized instrument for measuring the smoothness of paper. It is designed based on the working principle of the internationally recognized Bekk smoothness tester. The instrument's mechanical design eliminates the traditional manual pressure application structure using a lever and weight, innovatively employing a cam and spring, utilizing a synchronous motor for automatic rotation to apply standard pressure. This significantly reduces the instrument's size and weight. The instrument features a 5-inch touchscreen display with Chinese and English menus. The interface is user-friendly and easy to operate, requiring only one button press during testing. The instrument also has the function of testing and calculating the difference between two surfaces. It utilizes high-precision sensors and an oil-free vacuum pump, among other advanced components. The instrument has functions for testing, converting, adjusting, displaying, memorizing, and printing all parameters included in the standard. It possesses powerful data processing capabilities, directly providing statistical results for various data points. These data are stored in the main chip and can be viewed via the touchscreen. With its advanced technology, comprehensive functions, reliable performance, and convenient operation, the instrument is an ideal testing device for industries and departments such as papermaking, packaging, scientific research, and product quality supervision and inspection.

Key Performance Features:

One-button intelligent operation.

1. Adopts a cam-and-spring structure design; during measurement, the microcontroller automatically controls the synchronous motor to rotate, apply pressure, and clamp the paper.

2. Features a 5-inch touchscreen display with Chinese and English menus, displaying various data in real time.

3. Fast measurement: Small-volume chamber measurement is available, with measurement time only one-tenth that of large-volume chambers, achieving rapid measurement.

4. High degree of automation: The instrument design utilizes advanced domestic and international components; a single-chip microcomputer handles information sensing, data processing, motion control, and data storage.

5. Oil-free vacuum pump: Employs a vacuum pump, eliminating the need for oiling.

6. Excellent sealing: Utilizes vacuum sealant and advanced sealing technology, ensuring the instrument's sealing meets national standards.
