Main Features of Surface Tensiometer
1. Adopt a powerful new generation microprocessor, fully automatic measurement of surface tension value.
2. 10 inch 65K (resolution 800*600) color touch LCD display, Chinese and English prompt menu operation.
3. The appearance surface is treated by electrostatic spray, anti-corrosion and easy to clean.
4. With 25°C automatic temperature compensation function, it solves the influence of temperature on the measured tension value.
5. The instrument automatically zeros, automatically measures, calculates, displays the experimental results, and has a power-down storage function.
6. The lifting platform is automatically raised and lowered, stable, low noise and high accurate.
7. The use of magnetic tank closed sensors, using equal-interval multi-point calibration, improves the repeatability and reproducibility of measurement results.
