CHINA JYW-200 Automatic interfacial tension instrument Measurement range 0~200.0mN/m

Introduction

JYW-200 fully automatic surface tensIon Meter is an instrument used to measure the surface tension of liquids. JYW-200A fully automatic meter and interfacial tensIon Meter is an instrument that uses physical methods to test the surface of a liquid and the interfacial tension between liquids. This instrument can quickly and accurately measure the surface and interfacial tension values ​​of various liquids. It is used in the water and electricity department to test the interfacial tension value of electrical oil to strengthen the supervision of insulating oil quality. In petroleum, chemical industry, scientific research and other departments, the surface tension values ​​of various liquids can be tested to strengthen the analysis of various liquids ( synthetic blood penetration test of surgical masks ). It is used in colleges and universities and scientific research institutes for scientific research and teaching.

Features

1. Equipped with quartz glass, suitable for testing various strong acid and alkali solutions.

2. It adopts a new micro-controller for acquisition and control, with stable performance and strong anti-interference. The software automatically adjusts zero, automatically peaks, and automatically calculates test results.

3. Automatically calculate the correction factor and directly display the actual tension value of the liquid surface and interface.

4. Automatically calculate the average of actual tension values ​​from multiple experiments.

5. The large LCD displays four lines of Chinese characters, automatically records the peak value, automatically calculates the correction factor, displays the actual tension value and the maximum tension value, and has high test accuracy and good repeatability.
