- Auto Lock mechanism
This function automatically locks the rotor to protect the pivot shaft when measurement is finished. The mechanism allows easy attachment and removal of the rotor while protecting the bearing from damage, making it very easy to operate, even for first time users.
- Zero Span setting function
Calibration corrects for viscometer-to-viscometer variances - resulting in high accuracies which exceed catalog values.
- Preheat / Auto Stop functions
The Model R85 also features preheat and auto stop functions.
The preheat feature operates also as an auto start function.
Automatic viscometer operation can thus be obtained by combining the preheat and auto stop functions and the user can set startup and stop times at his discretion.
- Data interchangeability
Measurement data of the R85 viscometer conforms to JIS and ISO standards and is compatible with other Toki Sangyo cylindrical spindle and cone/plate viscometers.
- Power interlock function
The power interlock function ensures continued power until locking of the bearing is complete even when the viscometer is switched OFF during operation.
- Rotation slow up/slow down
Rotation speed changes are very smooth which prevents shock from being transmitted to the viscometer during measurement start, changes in speed, and measurement stop.
- Alarm warnings and display
Warning icons are displayed and an alarm is sounded when measurement data falls below 10% or exceeds 100%.
- Data recording
A calendar function is incorporated in the R85 viscometer.
In addition to measurement data recording, date, viscometer model, and other information can be printed out with a special printer.
