It is divided into two models.
It covers 3 ranges and It has a measurement range equivalent to that of three conventional viscometers.
This makes it possible to measure multiple samples with different viscosity values. In addition, since measurement can be performed at a wide range of rotation speeds (share rate), the range of sample evaluation is expanded.
Operating principle
The viscous torque detector is divided into a drive frame and a sensing frame, which are connected by a flex pivot.
A feedback current flows through the Torquer so that the deviation between the drive frame and the sensing frame generated during measurement becomes zero, pushing the sensing frame back.
This measurement method is a measurement method that always returns the deviation to zero (equilibrium) and is called the “zero position method”.
Due to the “pivotless mechanism” that does not use the jewel bearing used in conventional viscometers, it has excellent linearity and reproducibility even in a wide measurement range.
Program function (TV-200B only)
You can set 10 patterns of programs up to 40 steps.
Set “rotation speed”, “measurement range” and “measurement time” for each step. Since the operation is always fixed, stable measurement with good reproducibility is possible.
Non-Newtonian samples exhibit various behaviors depending on the timing of changes in rotation speed (shear rate) and the difference in measurement time.
Therefore, when measuring such a sample, by using the program function, it is possible to measure with a constant operation regardless of who is measuring it, so stable measurement is possible.
In particular, it is an essential function when you want to obtain flow analysis and TI value (thixotropy index).
Visco-Chart (Standard accessory for TV-200B only)
This software imports viscosity data into a computer.
graph in real time
By graphing in real time, sample characteristics can be visualized and easily evaluated. In addition, the simple analysis function can calculate the “hysteresis loop area” and “non-Newtonian viscosity index”.
Data compatibility
The TV-100B/200B viscometer conforms to JIS and ISO standards, and the measured data is compatible with other viscometers manufactured by our company.
