The rotor is a spindle type B-type viscometer.
The feature is that the measurement range is very wide due to the multi-range function.
One unit boasts the measurement range of three conventional viscometers and has excellent cost performance.
Recommended when you want to measure samples of various viscosities with one unit.
* The TV-200B series comes standard with viscosity data acquisition software (Visco-Chart).
Equipped with a 4.3-inch LCD color touch panel, the screen is easy to see and operability has been improved.
Depending on the viscosity value of the sample to be measured
Low viscosity：L type
High viscosity：H type
It is divided into two models.
Low viscosity (L type)
“M”, “2.5M”, “5M”
High viscosity (H type)
“H”, “R”, “U”
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.
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.
The TV-100B / 200B has a temperature display function.
By using the optional temperature sensor “PB-100”, it is possible to measure the sample temperature inside the measuring container.
