The viscometer works under the control of a PC (Laptop). In the dialog mode, the operator sets the parameters necessary for testing liquids. The test results are displayed on a PC display, stored in a database and can be printed on a printer. Technical specifications The range of viscosity determination is from 0 to 1000 MPa ×s. The limits of the permissible relative error in determining the viscosity under normal conditions are 1%. The rotational speed of the measuring nozzle is from 0.1 to 900 rpm. The range of temperature control and determination of the temperature of the tested solutions under normal conditions is from 10 to 50 ° C. The limit of permissible absolute error of temperature control and temperature determination ± 2 °C. Normal operating conditions under which metrological and reliability parameters are normalized: type of current – alternating single-phase; supply voltage – (220 ± 22) V; ambient temperature – from +15 to +25 ° C; AC frequency – (50± 1) Hz; power consumption – no more than 240 VA. Operating conditions under which the additional error in determining the viscosity increases by ½ of the main one: ambient temperature – from +10 to +35 ° C; The electrical insulation resistance between the electrical circuits and the housing at ambient temperature (20 ± 5) ° C and relative humidity (80 ± 3)% is not less than 20 mOhm.
