Automated Tensiometer
Fully automatic yet simple and precise
The successor to the TD 2 accomplishes the move to fully automated tensiometry and maximises user convenience directly over a PC. This extremely compact stand-alone device offers everything needed to measure surface and interfacial tension at the push of a button either in the laboratory or in the field as simply as possible. The accurate, reproducible results can be displayed, printed, saved, or transferred to a PC. With this device it is also possible to measure the density of liquids and to determine small weights. The convenient external control panel has a large graphic display that can be operated intuitively without special training. The integrated microprocessor handles sample positioning, force maximum detection, and data correction. The program repeats measurements until a user-defined stability is reached


and calculates static surface/interface tension and standard deviation over the last series of individual measurements, and compiles the results in easy-to-understand tabular format. With its rugged design, ease of operation, and high precision, the TD 2 is ideal for use in all quality control applications. Since measurements are taken completely independently by the user and documented together with the required settings, the device also meets the stringent requirements of the GLP guidelines.

Advantages:

- Easy to operate
- Transmits a direct feel for surface and interfacial tension
- Specially suited for beginners and in educational settings
- Digital display of surface and interfacial tension
- Results can be displayed, printed, saved or transferred to a PC
- Precise electromagnetic weighing cell
- Simple selection of measuring methods according to
.. Du Noüy-ring, Wilhelmy-plate,
 .. Lenard frame or density measurement
- Calibration with standard weights
Application examples:
  • Testing of cleaning water for detergent residues
  • Determination and testing of the physical characteristics
    of solutions
  • Development and testing of surface-active substances such as
    surfactants and emulsifiers
  • Detection of surface-active substances in wastewater
    and other water
