This equipment has been designed to optimize the dosage of coalescent in sewage disposal, that is to carry out the well known “jar test”. Multiple stirrers with reproducible stirring speeds allow to adopt standard conditions for the tests, that are the basic requirement for reproducible results. A special switch available on the front panel enables to backlight the sample being examined for easier readings. The rotation speed can be programmed from 10 to 300 r.p.m.
