I.Functional Features

◆Precision mandrel, in line with standard requirements, high test repeatability;

◆Using metal bath cold trap;

◆Standard glass test tube, inner diameter 22~22.5mm, length 120mm;

◆Special rotational viscometer, equipped with seven spindle speeds;

◆Semiconductor refrigeration, can be tested after 2 hours of constant temperature, compared with 18 hours of traditional air constant temperature, the efficiency is increased by nearly 90%;

◆Microcomputer temperature controller, PID adjustment, temperature control range: normal temperature ~-40℃, PT100 temperature sensor, high precision;

◆Large viscosity detection range, 1000~1000000mPa.s

◆LCD screen display, programmable selection of test speed, test time, automatic calculation of results;

◆ Equipped with CADON® analysis software, which can calibrate and analyze the linear accuracy of the viscometer very well;

◆One-key automatic lifting structure, automatic positioning of viscometer;

◆The test tube has a locking function to prevent the test tube from affecting the accuracy due to excessive viscosity.
