Shanghai Nirun is a domestic high-end brand, specializing in the production of viscometers. There are three different series of Rotational Viscometers, including NDJ series, SNB series and DV series. All of them can be used for viscosity detection in coatings, inks, adhesives, food, beverages, cosmetics, pigments, chemicals, pharmaceuticals and other industries, but they have different functional levels.
The NDJ series Rotational Viscometer is a simple viscometer, the SNB series is an economical and intelligent type, and the DV series is a classic type, which can be used for higher-end experimental testing research. The design of which series is basically the same, as shown in the figure below.
The structure and appearance panels of the three series of Rotational Viscometers are the same, using ruby bearings, driven by stepping motors, all controlled by microcomputers, the torque material is beryllium bronze, and LCD backlight display is used. The measurement accuracy is ±1.0%, repeatability The linear accuracy is ±0.5%, with timing function.
The differences between NDJ series, SNB series and DV series are as follows:
NDJ Series Rotational Viscometer
The NDJ series is a simple type, mainly used in the test of medium and low viscosity fluids in QC detection. It has two different rotor speeds, 4th gear and 8th gear. Equipped with a 400ml sample container, the lifting system is made of PE material, and can be equipped with a micro-printer and a special viscosity constant temperature Water Tank.
SNB Series Rotational Viscometer
The SNB series is economical and intelligent, mainly used in QC testing and process testing. It can test medium, high-low surface fluids. It adopts stepless speed setting of 0.1~100rpm. It is equipped with 1~4 rotors as standard, and the measuring sample capacity is 300~ 400ml, can be equipped with 400ml sample container, the lifting system is made of PE material, with RS232 communication interface, not only optional micro-printer and special viscosity constant temperature Water Tank, but also optional sales sample adapter and temperature-controlled heater, equipped with data acquisition And dedicated software for drawing and PTD temperature head.
DV Series Rotational Viscometer
The DV series viscometer is a classic type, used for QC and research of fluid properties. It can test low, medium and high viscosity fluids. The continuously variable speed range is 0.1~200rpm. It is equipped with 1~4 rotors or RV1~RV7 rotors as standard. All the functions of the SNB series Rotational Viscometer support a larger sample capacity, up to 600ml, and the lifting system is made of metal. The standard software can not only collect data and program control, but also analyze data. It is equipped with PT100 temperature probe, RS232 communication interface, paddle rotor and DIN adapter meter HELIPATH STAND.
The above is the difference and comparison of the three series. When choosing a Rotational Viscometer, customers can consult the technical engineers of Beichao, follow up the actual experimental test conditions, and choose a suitable Rotational Viscometer for the experiment.
