Platinum Plate Board Surface Tension Meter Automatic Interfacial Tensionmeter

I.Summary

This is HZ1731 full automatic surface tension tester including platinum plate method and platinum ring method produced by . The surface tension is a basic property of liquid, especially surfactant aqueous solution. Can measure the surface tension value of various liquid quickly and accurately with physical method instead of chemical method. It has a wide range of application. It can measure surface tension in hydropower sector to strengthen supervision on the quality of insulating oil; it can measure and analyze the surface tension value of various liquid in petroleum and chemical industry, scientific research and education department.

Platinum plate method)

When the platinum plate is immersed in the liquid to be measured, the surface tension will occurs around the platinum plate. The surface tension of the liquid will try to pull plate down. When surface tension of the liquid and other related stress are equal to the equilibrium force, the platinum plate will stop. At this time, the balance sensor will measure the immersion depth, and convert it to the liquid surface tension values.

Steps:

(1) Raise the platform;

(2) When the bottom of the platinum plate contacts with the liquid surface, the equilibrium value is measured by the sensor and converted to the surface tension value to display.

Platinum ring method

A circular membrane between testing part and the liquid sample will be formed with this method.

Steps:

(1) Immerse the platinum ring gently into liquid inside.

(2)The platform descends and then a bubble film forms below the platinum ring and eventually leaves it.

(3)The equilibrium value is measured by the sensor and converted to the surface tension value to display.
