Rheological characteristics obtained for a concrete material are not always reproducible if different rheometers or their geometrical arrangements are used. However, this point has hitherto been discussed rather rarely. This situation seems to be more chal- lenging since the introduction and application of so-called smart materials. The aim of this contribution is to compare the electrorheological characteristics of suspensions (5, 10, and 15 wt.%) of PANI powders suspended in silicone oil measured by a rotational rheometer Physica MCR 501 (Anton Paar Co.) equipped with two different geometrical arrangements— parallel plates and concentric cylinders. The coincidences or differences in the results of the individual measured parameters are discussed.
