The UFIT Viscosity-Systems

UVS®, UFIT Viscosity Systems for automated determination of liquid viscosity of polymers and kinematic viscosity of petroleum products
due to ASTM D 665 in capillary viscometer.
The flow time is optically measured with an exactness in milliseconds. We also measure the exact flow time per thermistors in case of opaque appklications, like used motor oil.
You can find in our UVS® systems solvent and acid resitant pumps and valves, to ensure to measure any kind of application.

The modular concept of our UVS® systems allows customer specific configurations, like baths with different temperature, sampling und multi channel measuring.
Der measuring process like pretemperature, measuring, suction, rinsing and drying, plus the analysis and archiving of the measured data happens automatedby our software VisKey,
which runs on a Windows PC with USB-
interface. The software supports up to 8 independent channels at same time !!!
can measure the viscosity of following polymeres:

Polyamide (PA),                                                 Polyester (PET / PBT / PCT / PEN),                                          Cellulose acetate (CA),
Polyvinylchlorid (PVC),                                     Polyethylen (PE / PP),                                                                Polymethylmethacrylate (PMMA),
  Pulp,                                                                   Cellulose,                                                                                      Polyisobutene (PIB),
    Polycarbonate (PC),                                              Polystyrene (PS),                                                                               Polyphenylene sulfide (PPS),
       watersoluble Polymers,                                         Enzyme kinetics

Of course the system can measure also other polymers.

can measure the viscosity of folowing oils (transparent, colored oder opaque):
crude oils                                                   base oils                                       transmission oils
   distillate                                                     petrol E20                                    motor oils
      kerosene                                                   biodiesel                                      coolants
         jet fuel                                                       paraffin                                        used motor oils
           residual fuel oils                                        petroleum                                     photoresists
              synthetic oils                                             wort                                              blood

calculate in situ the result and support a variety of formulas.

formic acid,                                           sulfuric acid,                                   dichlormethane,                                                      chloroform,
   m-cresol,                                               phosporic acid,                                toluene,                                                              isooctane,
      phenol,                                                    tetrachloroethane,                         water,                                                                   sodium chloride,
