Overview 
The Rheocheck MD - Drive measures the cure characteristics of a rubber compound in conformity with the international standards ISO 6502-3 and ASTM D 5289.
The measure of the vulcanization is carried out by measuring the modification in the mechanical characteristics of the sample. The instrument permits to apply a cyclic strain to a test piece and to measure the associated force. The test is performed at a defined temperature and the measure of stiffness recorded continuously as a function of time.

Automatic sample loader 
The device allows to position 5 test pieces on the loading slide and automatically perform the tests on all the samples.
Before starting a test, the software automatically regulates the instrument according to the test conditions required for the next sample in the queue.
When the test conditions are within the expected tolerance limits, the sample loader moves the sample in the right position and starts the test.

Test dies 
Pressurized test chamber conforming to the international standards.
The formulation for the seals has been specifically developed by Gibitre to ensure Low friction and long duration.
The micrometric adjustment of the distance between the chambers is carried out independently by the exclusive mechanical adjustment vernier. The device allows you to easily adjust the thickness of the specimen to meet the requirements of ISO 6502-3.
The thermal insulators, used to avoid heat transmission, have been chosen for their excellent mechanical characteristics and low thermal conductivity.
The insulators are coated with a surface treatment based on fluorinated polymers, which ensures extremely high resistance to chemical agents and ease of cleaning.

Temperature regulation 
The regulation of the temperature is performed using thermo-regulators with PID micro-processor and with 0.1°C resolution.
Independent temperature control units ensure sophisticate temperature control and easy replacement in case of failure.
Electrical heating resistances have been specifically designed for this instrument to ensure quick and efficient heating.
The test chambers are equipped with a compressed air cooling circuit, controlled by the temperature control units, which allows rapid temperature reduction.

Torque Calibrator Supplied 
The supplied torque calibrator allows the user to periodically check the torque reading of the instrument.

The calibration wizard inside the software:
• Requires the insertion of the calibrator between the instrument surfaces
• Waits for the thermal conditioning of the instrument
• Performs the comparison between the instrument measurement and the calibrator torque value
• Requires removal of the calibrator after verification

Datagest program 
The Datagest program is the database management tool always installed in combination with all Gibitre instrument-control programs.
The program permits to:
• Select, filter, print, export and analyse the test results stored with all the instruments connected.
• Prepare test procedures by defining the test conditions and the results to be produced
• Set tolerance limits for each product by manual insertion or using the statistical analysis (mean and standard deviation) of saved results
• Prepare multi-instrument test reports
