JJ2000B Rotating drop ultra-low interfacial tension meter

JJ2000B Rotating drop ultra-low interfacial tension meter

Brief introduction 

JJ2000B type rotating drop interface tension measuring instrument is based on the latest research results of the domestic and colloidal chemical experts, the advantages of integrated domestic and foreign similar products, the use of computer control and multimedia technology in the latest research and development of new products. The apparatus is a special instrument for measuring the surface tension of liquid, liquid / liquid interfacial tension and liquid / solid contact angle. 

Features

1 all the process is controlled by the PC computer and the front single board computer. The image of the rotating liquid drop is analyzed and calculated by using the computer multimedia video technology. It has very good operability and repeatability. 

2 master control program is the Winndows interface, easy to operate, the image is the standard BMP file, can be stored print. 

3 tension measuring range, from 10-5mN/m to 100mN/m, across seven orders of magnitude, for the full range of tension measuring instrument. 

4 measuring accuracy, provide a number of file amplification rate, can be enlarged to more than one hundred pixels hair width, greatly improve the accuracy of the ultra low interfacial tension. 

5 with electric heating system, can be a constant temperature.
