Ⅲ. Feature:

① ARM technology, built-in Linux system. The operation interface is simple and clear, and the viscosity test is performed quickly and conveniently through the creation of test programs and data analysis;
②Accurate viscosity measurement: each range is automatically calibrated by computer with high precision and small error;
③Rich display: in addition to viscosity (dynamic viscosity and kinematic viscosity), temperature, shear rate, shear stress, measured value as a percentage of full scale value (graphic display), range overflow alarm, automatic scan, current rotor speed combination The viscosity measurement range, date, time, etc. The kinematic viscosity can be displayed at a known density to meet different measurement requirements of the user;
④Full-featured: timed measurement, self-built 30 sets of test procedures, access to 30 sets of measurement data, real-time display of viscosity curves, print data and curves, etc.
⑤Front level: horizontal adjustment is intuitive and convenient;
⑥Stepless speed regulation: RV1T series: 0.3-100 revolutions, a total of 998 speeds
RV2T series: 0.1-200 revolutions, a total of 200 speeds
⑦Shows the shear rate vs. viscosity curve: displayed in real time on a computer, also showing the time or temperature vs. viscosity curve
⑧Optional Pt100 temperature probe: wide temperature range, from -20 to 300℃, temperature measurement accuracy of 0.1℃;
⑨A wide range of optional accessories: special thermostatic bath for viscometer, thermostatic cup, printer, standard viscosity sample (standard silicone oil), etc.
⑩ Chinese and English operating systems.
The DV1T/DV2T series stepless speed-adjustable touch-screen rotary viscometer can measure a very wide range from 10 mPa.S to 320 million mPa.S, covering almost all samples. The R-series disc rotor can be used in the same way as the same type of viscometer from Brookfield.
