1、 Overview:

The JYW-200B fully automatic interfacial tension meter is a simple and practical testing instrument that uses physical methods instead of chemical methods. The automatic interfacial tension meter can quickly and accurately measure the surface and interfacial tension values of various liquids, and automatically display the results. In the water and electricity sector, it is used to test the interfacial tension value of electrical oil to strengthen the supervision of insulation oil quality. In the petroleum, chemical, scientific research and other sectors, it can test the surface tension value of various liquids to enhance the analysis of various liquids. For the education sector, it can be used in teaching.

2、 Compliant with standards:

1. GB/T 22237-2008 Surface active agents Determination of surface tension

2. JB/T 9388-2002 Technical Conditions for Interface Tension Tester

8. GB/T 5549 (ISO304-1985) Determination of surface tension by pulling film method

3、 Instrument features:

1. The circular ring method testing, compared to the plate method, has been validated for many years and is more widely used. It has higher testing accuracy for the tested liquid within the measuring range of the circular ring method (0-200mN/m).

2. The tension value can be displayed directly without the need for formula calculation.

3The electrical system adopts Taiwan's DeltaPLCModular independent electrical control system, with interchangeable components of different products, strong universality, stable performance, high precision, and extremely low failure rate.
