Features:
1. Features a unibody casing and precision direct-drive mechanism, significantly enhancing instrument reliability and durability. The vibration-free transmission ensures physical stability for improved testing accuracy.
2. Utilizes a micro stepper motor for the lifting platform, enabling high-speed adjustment to enhance efficiency and reduce testing time. Automatically switches to standard speed during measurement to guarantee precision.
3. Equipped with a 32-bit ARM microcontroller for high-speed operation and computational accuracy. A proprietary filtering algorithm ensures stable and accurate readings.
4. Incorporates a 24-bit AD converter for rapid signal conversion and highly accurate force value acquisition.
5. An improved torsion wire lever mechanism guides the sensor core in a near-linear path, ensuring excellent test linearity.
6. Employs a high-end domestic LVDT displacement sensor with superior linearity, sensitive signal output, and precise impedance matching, guaranteeing repeatable test accuracy.
7. Includes an auto-stop function configurable for surface tension tests. The platform halts automatically upon completion and displays the tension value.
8. Offers an automatic averaging function, which calculates and displays the mean of multiple tests, reducing operator workload and effort.
9. Features a digital LCD screen that simultaneously displays real-time data and final test results, allowing for direct and convenient reading.
