Introduction

It mainly measures substances that are solid at room temperature and become liquid after heating at high temperature, such as asphalt, hot melt adhesive, polyethylene wax, etc.

It can be used as a stand-alone machine, and the measurement data can be directly displayed on the LCD without secondary calculations; it can also be equipped with "data collection analysis and drawing software" to realize data collection and data analysis, and monitor the viscosity-temperature curve throughout the process.

Using high-resolution stepping motor, the speed is accurate and stable.

LCD liquid crystal with blue backlight function, directly display viscosity, speed, percent torque, rotor number, and the maximum viscosity value and temperature value that can be measured at the current speed of the selected rotor. DV-2 series can also display shear rate and shear stress. The viscosity value shows a continuous change, and there will be an alarm sound when it exceeds the measurement range. 

The measurement performance of the instrument has reached the level of foreign products of the same type through computer correction. 

The high-temperature furnace adopts built-in overall heating, which is evenly heated and has small thermal inertia.

FAQ
Q20-1 million mps The sample temperature is 80-150 degrees Celsius, right? How many samples do you need for this test? Organic Glass pmma
A Generally, the melting point of PMMA is about 160 ° C. If you want to measure this material by yourself, it is more troublesome to measure it by Viscometer. You need to measure the thermostatic temperature all the time. RVDV-1H is recommended.
QViscosity of epoxy resin Is there a solid epoxy resin viscometer? Can it be measured for solids?
A Solids are measured after heating dissolved Use SNB-RH, RVDV-1H, RVDV-2H after solvent dissolving at room temperature or heating to more than 100 degrees for measurement
QNeed to test the viscosity of epoxy resin, including thermostatic controller, this one can be tested, I want to know how long the temperature and rotor display viscosity value can be displayed on the machine
A Room temperature, direct measurement is enough. If you need to control the temperature of your epoxy resin, it is recommended to choose NDJ-8S or LVDV-1 with LC-1008 low temperature Thermostatic bath, the viscosity is stable and the result is obtained. The whole China 5-8 seconds
QIf it is 200 ° C in the furnace, what is the temperature outside the furnace?
A We do a better job of heat insulation, and the temperature outside the furnace is controlled within about 45 ° C
QThe measurement of plastic particles requires high temperature heating and stirring, and the temperature should reach about 280. Can it be tested?
A 280 degrees can't be measured if it softens, and can be tested if it dissolves. This one can reach 300 degrees.
QHow is the temperature control of the high temperature Viscometer heating device?
A The heating device is specially used for accurate measurement of the viscosity of hot-melt adhesives, paraffin, asphalt, drugs, high polymers and other high temperature liquids. The sample temperature can be controlled to room temperature + 5 ℃ - + 250 ℃. The temperature fluctuation of the heating device is precisely controlled +/- 0.1 ℃. The sample dosage is small 5-20ml, and it can be equipped with a disposable sample cartridge. It can be equipped with a standard SC4 rotor, which is easy to operate and use.
QHow to clean this?
A Like this kind of high-temperature Viscometer cleaning, generally take it down for cleaning under high temperature conditions. Don't wait for the temperature to drop, and then take it directly for cleaning, because it is not sticky under high temperature conditions. It is very annoying to wait until the temperature drops before cleaning. When the temperature drops, it will be more sticky. Some customers will soak it in solvent again.
QMeasure organic matter, oil, everything, is there a Viscometer with a wider viscosity range and heating function to 300 degrees?
A This one is ok.
QIs there a suitable Viscometer for measuring the viscosity of hot-melt adhesive particles?
A Hot-melt adhesive RVDV-1H, SNB-RH, RVDV-2H are all available.
QWe make hot-melt adhesives, what Viscometer recommend?
A Make hot-melt adhesive, RVDV-1H\ RVDV-2H\ SNB-RH can be used.
