Measuring stand S5

The S5 is the measuring part of the PVS system. Its head is comprised of the opto-electronic meniscus detectors as well as the entire control of the measuring process including miniature pump and valves.

The accuracy and resolution of the light sensor measurement system is among the best of its class. The robust micro-pump for pushing the sample up into the measuring ball as well as the chemical-resistant valves in the head of the stand allows reliable and continuous operation.


Special Features:

  • Completely micro-processor controlled for a highly precise time measurement
  • Adaptive infrared (NIR) detection
  • Short tubing to the viscometer
  • Electrical connections only
  • For (Micro-) Ubbelohde, Cannon-Fenske-Routine and Micro-Ostwald capillaries

Software based on Windows

All PVS system configurations are controlled by a standard PC through an interface. In addition, the high-performance and user-friendly standard version of the software calculates the intrinsic, kinematic, dynamic, relative, reduced and inherent viscosity and the K-value from the measured running times. Further key material properties can be determined using additional software modules.

The measuring results and evaluations can be printed out and saved in a file in ASCII format. The measurements report logs all measuring data on a day in chronological order and saves them in a file marked with the day‘s date. This data can be viewed at all times which means that consistent documentation is guaranteed. Further processing in other programs like MS Excel and in other networks is possible.
