DH-ZY Series Fully Automatic Interface Tension Tester
Surface tension is a basic parameter to determine the liquid solubility,wettability,foamability,coatability,and permeability.,etc.
Features:
- The sensor is integrated with high accuracy and high sensitivity electromagnetic technology,and any error in manual operation can be avoided by automatic measuring to enhance the data accuracy and reliability.
- A Pt board or Pt loop can be chosen to measure the liquid surface and interface tension.
- The Pt board can be used to measure the liquid surface tension in real time,it is practicable for measuring any sample which contains any surface activating agent or volatile matter and whose surface tension will change with time.
- The Pt board can be used to measure the surface tension of any medium or high viscosity liquid sample.
- Various temperature control are optional to satisfy different measuring requirements.
