SMV-300 
Automatic Mooney Viscometer

Easy to Use man-machine interface
The test conditions and display results with simple LCD touch-panel operations.

Superior temperature recovery characteristics The optimally controlled film heaters ensure significantly faster temperature recovery after sample loading and improve temperature control stability. Faster recovery of the die temperature to the test temperature improves test efficiency.

Features Stress Relaxation Measurements
The instrument can conduct stress relaxation measurement and decay measurement according to ASTM D 1646 after measuring the Mooney viscosity, enabling viscoelasticity evaluation for the sample.

Variable Rotor Speed
Test can be conducted at multiple rotation speeds. This feature permits evaluation of milling at high shear rates, makes viscosity differences between samples more apparent by varying the strain, and allows viscoelastic evaluation. The speed can be set from 0.052 to 0.523 rad/s (0.5 to 5 rpm) in increments of 0.1 rpm.

Easy Cleaning
The new models retain the popular post-test rotor push- up mechanism and simple measurement mechanisms, offer surface treatment of the rotor and radial V-groove die to resist sample adhesion, and feature 0-ring seals.

Convenient Analysis Functions
The models boast comprehensive data analysis functions, including statistical calculations, data editing, and graph displays.

Dual Calibration Functions
Electrical sensitivity calibration by simple touch- panel operation as well as torque calibration with weights ensure highly reliable measurements.

Simple windbreak functions
Simple windbreak functions eliminate effects from the ambient environment during measurement.

Select Standard Tests or Easy Tests
Select standard tests that allow very precise setting of test conditions or easy tests that permit simple testing with the minimum setting of conditions, such as for multiple measurements with identical conditions.

Intermediate Result Confirmation
When multiple measurement conditions are input, the intermediate test results can be displayed on the screen and checked for any setting at any time during measurement, not just after measurement is complete.

Printing and Data Output Features as Standard
Select between an A4 inkjet printer and thermal roll- paper printer (printers are options). Communications via RS-232C interface. Standard data output functions can transfer all measured data (test conditions, test results, raw data) to a PC.

Warm-up Function
The warm-up function starts heating to the set temperature at a fixed date and time. Two hands are required to start test operation, ensuring safety. When the optional windbreaker casing is used, the auto-start function automatically starts the test when the door is closed.The overload prevention and overheat prevention mechanisms further enhance safety.

Test-Over Buzzer
The buzzer sounds to notify that the test is complete.
