Advantages of High-precision Measurement
1）Measurement range: 2-100 mN/m (petroleum products), 2-200 mN/m (other products). Accuracy: ±0.1 mN/m, resolution: 0.1 mN/m, meeting strict testing standards for data precision.
2）Adopts improved closed electromagnetic force balance sensor, enhancing response speed and linearity. Only single-point calibration is required to ensure measurement accuracy, replacing traditional multi-point calibration and potentiometer adjustment with stronger stability.
3）Built-in Wien bridge sine wave oscillator and high-speed precision operational amplifier with low waveform distortion, ensuring signal stability during complex sample measurement and reducing the impact of external interference on data.
4）Repeatability error ≤ 2% of the average value. Combined with automatic temperature compensation function (based on pure water calibration), it can effectively offset measurement deviations caused by environmental temperature changes, guaranteeing data reliability.

Multi-industry and Multi-scenario Adaptability
I. Compatible with two types of tension measurement: liquid-air and liquid-liquid. It can meet different detection needs such as water interfacial tension of petroleum products and surface tension of natural latex, adapting to multi-industry application scenarios.
II. Supports critical micelle concentration (CMC) determination of surfactants. By measuring surface tension at different concentrations, a tension-concentration curve can be drawn to derive the CMC value, providing key data for chemical research and development and quality control.
III. Strong adaptability to working environment: temperature 10-40℃, humidity 20%-75%RH. It can operate stably in laboratories, production workshops and other scenarios without special environmental modification.
IV. Adapts to various sample types, including oil products in the petrochemical field, pharmaceutical preparations in the medical industry, and insulating liquids in the power industry, all of which can complete tension detection accurately.

Intelligent Operation and Data Management
Equipped with an LCD Chinese display screen, the interface clearly presents five functional menus including weight calibration, parameter setting, and sample testing.
The operation logic is concise, and it can be used without professional training. Supports preset of sample density, working temperature and other parameters, and data is automatically confirmed after input, simplifying the operation process.
Built-in data storage function can save multiple test results, supporting automatic calculation of arithmetic mean for convenient data comparison and analysis. Optional printer allows on-site printing of test reports, meeting the needs of data archiving and test record traceability.
