Gelnorm RVN

rotate, RS-232

The tests with Gelnorm - RVN are performed automatically and under standardized and reproducible conditions. The change of viscosity in the sample is determined by the power increase required by a periodically rotating spindle probe. All results remain stored and can be reprinted until the next experiment is started. Using a special program, the data can be transmitted to a computer for further data analysis using MS-Excel. The new Online Software has more possibilities to describe your test and it shows also the graph directly.
