NDJ series viscometer is a digital display viscometer with high subdivision drive stepper motor, 16-bit microcomputer processor as the core, digital liquid crystal with blue backlight function. The speed of the instrument is stable and accurate, the keys are clearly marked, the operation is simple, and the program design. When the torque is lower than 20% (or 10%) (subject to the alarm limit of the instrument) and higher than 90%, the measuring instrument will sound an alarm. The screen directly displays the viscosity, rotational speed, percent scale, rotor number and the maximum viscosity value that can be measured at the current rotational speed of the selected rotor. The main control board and the subdivision driver board all adopt patch technology, and the circuit design adopts the current professional microcomputer processor, and the structure layout is reasonable and compact. Provide RS232 interface, the printing interval can be set by the user. The instrument's full scale and linearity of each gear are all measured and corrected through the PC interface, and its performance and functions have reached the professional level of the same type abroad.
SNB series viscometer is an upgraded product based on NDJ series viscometer. In addition to the performance and characteristics of the NDJ series viscometer, the SNB series viscometer has a wider measurement range; the speed selection is changed to a full-range stepless speed change; the RTD temperature probe is equipped to monitor the viscosity temperature in real time, and the accuracy can reach 0.1 ℃. The temperature measurement range is 0°C -120°C; optional SNB data acquisition and drawing software can perform fully automatic data acquisition, data storage and historical data comparison through the PC interface, and many other mathematical statistical analysis tasks.
The DV Series Digital Viscometers are the most versatile viscometers in the world. The instrument is cheap and good, and is well received by customers. Its functions and performance have reached the professional level of foreign products of the same type. In addition to the performance and features of the SNB series viscometer, it can also perform accurate shear rate and shear stress measurement. Two-way RS232 interface, can communicate with computer to realize program control and data acquisition. Purchase DV program-controlled offline download software to download the custom measurement program to the instrument to realize automatic and personalized operation. Purchase DV data collection and program-controlled analysis software to realize computer-automatic collection and analysis of fluid rheological characteristic curves, and also realize data storage, historical data comparison and other functions.
NDJ series, SNB series, and DV series viscometers are used to measure the viscous resistance of liquids, that is, the dynamic viscosity of liquids. Widely used in the determination of the viscosity of various fluids such as oil, paint, ink, food, paint, paper, cosmetics, chemicals, capsules, adhesives, glue, precision ceramics, resin, toothpaste, lithium battery slurry and medicine.
