Surface tension testers are widely applied in scientific research, industrial production, and quality control fields. Their main applications include:
1.Materials Science:
Measuring surface tension of liquids like coatings, inks, and adhesives, and evaluating their wettability and spreadability.
2.Chemical & Petroleum:
Analyzing surfactant performance and crude oil interfacial tension to optimize process flows.
3.Pharmaceutical Industry:
Testing surface tension of drug solutions to ensure drug stability and dispersion.
4.Food Industry:
Researching surface characteristics of emulsifiers, beverages, etc., to improve product quality.
5.Biomedicine:
Measuring surface tension of biological fluids (e.g., blood, cell culture media) to assist in disease diagnosis and research.

Characteristics:

1.Adopts advanced strain or electromagnetic force balance sensor, featuring high precision and excellent repeatability.
2.Digital tube display mode for real-time display of current weight and surface tension value.
3.Integrates both platinum plate and platinum ring test methods, allowing single or simultaneous selection.
4.Real-time collection of surface tension values with full-process curve recording. The software automatically displays the peak surface tension and converts the equivalent value according to temperature.
5.Convenient lifting bracket for platinum plate and ring, enabling easy loading/unloading. Force value accuracy can be calibrated anytime using standard weights.
6.One-key peeling function ensures stable readings without zero drift or numerical jumps.
7.Smooth ball screw lifting system operates noiselessly with stable up/down speeds.
8.Provides data collection and management software.
9.Complies with (but not limited to) the following standards:
GB/T6541-86, ISO1409-1995, GB/T22237-2008, SH/T1156-95
