Smoothness Tester ZY-PHD10

Application：

The ZY-PHD10 Fully Automatic Smoothness Tester is designed based on the operating principle of the internationally recognized Bekk smoothness tester and is a specialized instrument used to measure the surface smoothness of paper. Under specific contact conditions and a given pressure difference, it takes a certain amount of time for a specific volume of air to permeate between the sample surface and the annular surface; this time is expressed in seconds (s). The longer the time, the better the paper’s smoothness; the higher the smoothness, the better the print quality.

Test Principle (Buick Method / Air Leak Method)：

1. Clamp the sample between a standard polished glass surface and a sealed probe, and apply a standard pressure.
2. Create a sealed air chamber and record the time it takes for a fixed volume of air to leak through the gap between the sample and the glass.
3. The smoother the surface → the smaller the gap → the slower the air leaks → the longer the time → the higher the smoothness.

Key Performance Advantages:

1、 Features a large 7-inch color touchscreen with Chinese and English menu options, an attractive and user-friendly interface, and simple operation; testing can be performed with a single button press.What materials is the ZY-PHD10 Smoothness Tester suitable for?
2、Equipped with a vacuum pump imported from Germany that operates without oil, ensuring oil-free and pollution-free operation.
3、 Utilizes a cam-and-spring mechanism driven by a synchronous motor to automatically rotate and apply standard pressure.
4、 Incorporates imported vacuum sealant and advanced sealing technology, ensuring the instrument’s sealing performance meets national standards.
5、Equipped with a 32-bit ARM processor, which enhances processing speed and enables more precise and rapid data calculation;
6、 The instrument is equipped with a standard RS232 interface, allowing communication with PC software (optional);
7、 The instrument supports all parameter testing, conversion, adjustment, display, storage, and printing functions specified in the standard. It possesses powerful data processing capabilities and can directly generate statistical results for various data sets.
8、Two-Surface Difference Test: By selecting the two-surface difference test mode, you can test and calculate the difference between the two surfaces of a single batch of specimens.
9、Rapid Measurement: You can choose between “Auto Mode” or small-volume chamber measurement. In “Auto Mode,” the measurement time does not exceed 200 seconds, while the measurement time for the small-volume chamber is only one-tenth that of the large-volume chamber, enabling rapid measurement.
