An ideal rheometer for industrial quality control, regardless of industry. Various accessories and measuring geometries that can be connected using quick couplings. VT iQ can be equipped with an engine with mechanical bearing or air bearing.
With the new Haake Viscotester iQ, you can measure viscosity and rheological parameters using the central cylinder, Cone-Plate or and Plate-Plate geometries. The VT iQ Viscotester uses the quick and precise Peltier technique or conventional liquid circulation to control the temperature. If necessary, the sample can be measured directly in its original container by using a Vane probe or a submersible central cylinder with an open base. For the consumer packaging of cosmetics and food, an adjustable universal holder attached to the device frame is suitable. When using large containers, iQ can be attached to a robust holder with a quick lock, up to container size of 19 cm.
The VT iQ with a touchscreen identifies the connected geometry and temperature control unit. The analyses are always done with the correct parameters.
A brand new one-hand quick lock has been developed for attaching probes. The VT iQ automatically identifies the connected measuring geometry and temperature control unit. Your measurements will succeed every time!
The system is controlled with its dedicated and clear touchscreen. The measuring parameters can be set fully manually, or the desired measuring method can be selected from presets. The VT iQ menu comes in a variety of languages. Each method can be connected to several QC criteria, in which case the system will show a simple message, QC = OK or QC = failed, directly on its own touchscreen after the measuring is done. Optionally, the system can also be accessed via a computer with the RheoWin software.
Presenting measurement data as graphs and numerical values
The measuring progress can be monitored on the system screen as a graph or a table. In the numerical tab, you can monitor the development of two essential parameters on a colour-coded progress bar. This feature is especially useful when you are testing unknown samples or developing your own methods for future use.
Oscillating measurements
Conventional lab equipment provides data on sample viscosity through rotational measuring. Often, this data is not sufficient to explain all of the product’s features since most mixtures also has elastic qualities. Until now, you needed oscillating measurements with a research-level rheometer to determine elasticity. Viscotester iQ introduces oscillation to production control and quality control laboratories, giving you an overview of your sample quickly and easily. In addition to conventional viscosity, the same system provides information about characteristics like structural stability and the product’s behaviour for its final purpose, even on the same sample.
