1. 【Dual Measurement Methods】 Supports both Wilhelmy plate method and Du Nouy ring method for surface and interfacial tension measurement. Direct data reading without manual calculation. Plate/ring design and dimensions comply with domestic and international standards. (Plate or ring configuration must be specified when ordering; both are recommended for maximum flexibility.)
2. 【High-Precision Electromagnetic Force Sensor】 Equipped with a high-precision mechanical electromagnetic force sensor using premium core components. The highest precision can reach 0.001 mN/m (Q500 model), ensuring accurate and reliable measurement results.
3. 【Three Models for Different Accuracy Needs】 Available in three models — Q2000 (0.1mN/m accuracy, 0-2000mN/m range), Q1000 (0.01mN/m accuracy, 0-1000mN/m range), and Q500 (0.001mN/m accuracy, 0-500mN/m range) — allowing users to select the most suitable instrument based on their precision and measurement range requirements.
4. 【7-Inch Touch Screen with Intuitive Operation】 Features a 7-inch touch screen that clearly displays all information and enables complete operation without the need for a connected computer. Supports Chinese and English interchangeable display for global user convenience.
5. 【Automatic Sample Stage & Adjustable Speed】 Built-in measurement program automatically controls sample stage lifting and lowering, eliminating human interference during measurement. Lifting speed is arbitrarily adjustable from 0 to 300mm/min, accommodating various experimental requirements with excellent repeatability.
6. 【Spacious Measurement Area with Illumination】 Spacious measurement area equipped with built-in illumination that brightly lights the sample surface and measuring body, making sample positioning extremely easy. Transparent glass sliding door protects the chamber from disturbed airflow for stable measurement.
7. 【Electronic Level Adjustment】 Built-in electronic level aids in precise adjustment of the sample stage, ensuring accurate force measurement by maintaining proper horizontal alignment.
8. 【Comprehensive Data Management】 Built-in measurement data management menu allows easy data viewing and supports external printer operation. All measurement data files can be transferred via USB flash drive and converted to Excel format for convenient management, recording and organization. Password management function ensures data traceability and prevents unauthorized modification or accidental deletion.
9. 【ST Flash Software for Advanced Analysis】 Includes ST Flash software with clear user guidance, supporting automatic summary charts, comprehensive measurement reports, and transparent data organization. Features CMC (Critical Micelle Concentration) analysis and calculation toolkit, supports simultaneous comparison of up to 8 sets of data, and allows data labeling for easy viewing and comparison. Supports both Chinese and English operation and display.
10. 【Liquid Density Measurement Function】 Based on the buoyancy principle, the tensiometer can immerse a standard-volume object into the test sample and calculate liquid density value (available for Q2000 and Q1000 models with optional standard volume parts, range 0-3.000g/cm³, accuracy 0.001g/cm³).
11. 【Rich Optional Accessories】 A variety of expansion modules and optional accessories are available to meet many testing needs beyond routine measurement, greatly enhancing instrument flexibility and application scope.
12. 【Wide Temperature Measurement Capability】 Supports optional PT100 temperature sensor for temperature measurement ranging from -40°C to 250°C, enabling surface/interfacial tension testing under different temperature conditions.
13. 【International Standard Compliance】 Designed to comply with all GB/T, EU, ISO, DIN and ASTM standards for surface and interfacial tension, including ASTM D971 (oil-water interfacial tension by ring method), ASTM D1331 (surface/interfacial tension of surfactant solutions), ASTM D1417 (synthetic rubber latex), DIN EN 14210/14370, ISO 6889/304/1409, ensuring measurement results are recognized worldwide.
14. 【Extensive Application Fields】 Widely used for evaluation of surfactant effectiveness and CMC measurement, wetting properties of tablets and pharmaceutical ingredients, wetting of paints and coatings, oil aging degree detection, coating wetting and adhesion testing, cosmetics development, ink wetting characteristics research, and more. Ideal for quality control, R&D and production in chemical, pharmaceutical, petroleum, coating, cosmetic and material science industries.
