Overview 
Gibitre OD Rheometer measures the cure characteristics of a rubber compound in conformity with the international standards.
The measure of the vulcanization is carried our by measuring the change 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 carried out at a constant temperature and the measure of stiffness recorded continuously as a function of time.

Instrument Characteristics 
Easily accessible test chamber with transparent safety panel and safety lock.
Test chamber in compliance with international standards.
Direct test chamber heating controlled by thermoregulators with PID microprocessor with O.1 °C accuracy.
Control system for compressed air pressure, cleaning and lubrication.
Pneumatic Rotor ejection and clam- ping systems.
Easy-to-change rotor oscillation amplitude.
Designed for eventual application of a fume aspiration system.

RheoCheck program 
• Graphic representation of the following curves: Elastic (S’), Viscous (S”), Complex (S*), Curing Speed, Tan-Delta, upper and lower test chamber temperatures.
• Display and printing in different colors of the relative test curves for rapid test identification.
Customer-defined test procedure with possibility of selecting up to 20 test results to be stored and printed (see table).

• The elastic curves relating to the tests carried out are superimposed at the end of the test with different colors to allow rapid identification of the tests.
• Automatic generation of tolerance limits from statistic analysis (mean and standard deviation) of stored results.
• Checking of whether results comply with tolerance limits and relative statistic analysis (Mean, St. Dev., Max, Min, Cp, Cpk).

 
• The test report, printable in a language of your choice, can include, in addition to the numerical results and the identification of the test, the tolerance limits, the statistical analysis, the curves, a legend of the results and your notes.
• The Gibitre-Rheocheck program connects to the Gibitre SQL Standard database.

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

Standard Calibration service for Oscillating Disk Rheometer. 
The calibration is performed with reference to the requirements of ISO 3417 standard.
The service includes:
• Ordinary maintenance of the instrument
• Calibration of the temperature of the dies at 3 temperatures (177°C, 190°C).
• Calibration of the time for temperature recovery at test start at 180°C (NEW)
• Calibration of the Torque (at 50 dN*m)
• Calibration of the torque standard supplied with the instrument.
• Final check with Standard Gibitre Compound (NEW)
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.

Accessories 
Volumetric die cutter.
Dies for OD rheometer with two Ø 8mm moulds.
Pressure sensor integrated in the upper die with 0.1 bar resolution.

Industry 4.0 integration 
The instrument and the software have been specifically developed to optimize integration with other environments.
The database in SQL format and the Gibitre_Company_Connect program allows you synchronize your company management software with Gibitre database and to speed up the identification of the tests and to use bar-code readers or similar devices.
The automatic logging service permits to send alarm information to the cloud-service platform of Gibitre Instruments in order to optimize the reaction times of the Service Support.
