The Gibitre Instruments Oscillating Disk (OD) Rheometer is a precision instrument for rubber compounds, designed to determine vulcanization behavior in accordance with ISO 6502-2 and ASTM D2084, and consistent with the principles of ISO 6502-1. The method tracks the time-based change in deformation resistance of a specimen with standardized volume under cyclic strain at defined temperature and pressure.
Standard-compliant chambers and rotor, with independent temperature controllers (0.1°C resolution), ensure tightly controlled conditions. Operation is immediate via touch-screen with illuminated status indicators. A transparent safety guard with sensor supports safe measurement.
Data handling is comprehensive: Rheocheck enables bar-coded sample identification, while Datagest manages the Gibitre Standard SQL Database. CE marking and a fume extraction interface complete the equipment.
Dedicated tools extend applications across materials: a pressure sensor for testing cellular rubber an
Overview
The Rheocheck OD - Drive measures the cure characteristics of a rubber compound in conformity with the international standards ISO 6502-2 and ASTM D2084
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.

The new 'Drive' generation
The new generation of 'Drive' instruments is the result of 40 years of experience in the measurement of rheology of rubber and incorporates the most modern technologies regarding mechanical construction, measurement sensors and control software.
RheoCheck_10 Software
The RheoCheck_10 program connects to the Gibitre SQL database and allows you to collect all the results within the Datagest data management program.
The program allows you to:
• Quickly identify the sequence of tests to be performed
• Automatically adjust the instrument according to the required test conditions
• Analyze the Test curves (S', S", S* Tang_Delta, Der(S'), Temperatures of the dies)
• Compare the results with the tolerance limits
• Elaborate statistical analysis (Carta-X, Gaussiana, Media, Dev St., Max, Min, Cp, Cpk)
• Produce customized reports
Calculated Results
The software allows you to prepare customized test procedures that include all the calculations required by the standards and product specifications. The dedicated page describes all the available calculations.
Pressure control
The instrument can be optionally equipped with a pressure sensor for the testing of the expansion evolution of the sample during the curing.
This option is useful for the analysis of cellular rubber formulations.
Instrument Control Panel
The instrument is equipped with a large touch-screen display with dimensions 10.2“. The buttons on the display permit to start and stop the tests. The display provides complete information about the status of the instrument: connection to the software, temperature of the dies, diagnostic of the sensors installed.
Light panel
A light panel, installed in the front part of the instrument, changes the color and permits to check the status of the instrument from a distance. The indicator light identifies the following statuses: Instrument ready, instrument under test, instrument setting test temperature.
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.
Datagest program: total Traceability
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
Gibitre Standard SQL Database
All the Gibitre programs use a database with SQL structure for saving the results.
The database can be installed inside an SQL instance present on the company server or it can be installed on a PC connected to a measuring instrument. The installation of the Microsoft SQL service (Express version) is included in the delivery.
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.
Preparation of Test Reports
Version 10 programs make the following options available for preparing test reports:
• Selection of printing language
• Company logo insertion
