Portable/Table-top Bubble Tensiometer

Portable/ tabletop instrument for dynamic surface tension measurement
User-friendly features:
 
  • Fast set-up
  • Compact and robust
  • Easy to operate
  • Quick measurements
  • Interchangeable capillaries
  • Long term measurement up to several days
  • Interface for process control is possible
  • Automated calibration
  • Touch key menu access for selection of operation mode, calibration and clean mode
  • Calibration against water
  • Allows measurements either at
    a) Constant surface age (bubble lifetime)
    b) Automatically increasing surface age (bubble lifetime)
  • Measurement independent of immersion depth---ease of switching among samples No density value of sample to be entered prior to measurement
