More Information
Summary:The utility model relates to a surface tension coefficient of liquid measuring apparatus measuring the surface tension of liquid by a micro-tension sensor. The apparatus measuring the surface tension coefficient of liquid by the spin-off method of the existing technology measures the tension by a Joly balance or a torsion balance with the disadvantages of big measuring error, poor repetitiveness and being easily damaged when in use. The utility model replaces the Joly balance, the torsion balance or a pair of scales with a measuring display instrument and the high-sensitivity micro-tension sensor consisting of a semi-conductor resistance strain gauge to measure the surface tension of liquid. The utility model with the advantages of simple structure, convenient operation, small measuring error, good repetitiveness and clear and directive physical conception expression can be used in physical and chemical experiment teaching and in the scientific research and industry.
