Multi-Unit Automatic Hardness Check
Multi-Unit hardness tester with automatic sample displacement. Up to 4 different Shore or IRHD hardness units can be installed on the instrument and quicky selected.
Multi-Unit Tester: Many instruments in one
• Multi-Unit Automatic hardness testing system has been designed for labs, which need to perform hardness tests according to different hardness scales.
• The hardness testing unit to be used must be placed in the front position by rotating the top part of the support.
• The rotating system permits to interchange the test unit within a few seconds.
• No dismounting or replacement of delicate parts and no specific training are required to perform with full safety this operation.
• This solid technical solution is ideal even in the case that the change of unit must be done many times in the same day.
Instrument Configuration
The instrument can be configured according to customer needs.
Up to 4 different heads can be applied to the support.
The measurement scales available are:
Shore A,
Shore D,
Shore A0,
Shore 00,
Shore AM (micro),
IRHD-Micro,
IRHD-Normal,
IRHD-Hard,
IRHD-Low.
The support is configured for the possible subsequent application of additional heads in the event that free positions are available.
Software or Display ?
To use the instrument for instant checks the control display is the simplest solution.
If you want to save the test results, the HardnessCheck Software is the ideal solution.
The two control methods can also be used together to combine speed of control and traceability of measurements.
Touch-Screen Display
The digital display is the optimal solution for the rapid use of the instrument. To carry out the test, simply press the start button. The test is carried out completely automatically showing the hardness value at the end of the test time.
No installation needed: just plug in the power supply and start testing
Unpack and Start measuring !
The instrument with Display does not need any installation: just plug in the power supply and start testing
Will I be able to install the software later?
Control needs often evolve over time.
If you want to start archiving your test results and producing test reports, you can add the software and connect the instrument to a PC via a simple USB cable.
Gibitre Hardness Software
The automatic durometer control through the Software Hardness-Check allows to exploit all the potential of the instruments:
• Perform multiple tests automatically on the specimen
• Save all test results to the SQL database
• Compare the results with the tolerance limits
• Produce test reports
The PC control software allows multiple instruments to be used simultaneously. Each instrument is connected to the PC via the supplied USB cable.
Calculated Results: IRHD Hardness
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.
Calculated Results: SHORE Hardness
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.
Management of Test Results
The results and test curves of all the tests carried out are saved in the Gibitre SQL database and are available through the Datagest program.
Datagest is the Laboratory Information Management System (LIMS) which is always installed in combination with all Gibitre instrument-control programs.
The program is the collector for all the test result produced with the instruments connected and permits to manage the common Archives used by the instruments (Product List, Customer List, Tolerance limits, Order List, etc)
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.
Universal Centring Device for O-Rings
The centering device allows to quickly carry out hardness tests on O-rings with rope between 1 and 11 mm and internal diameter up to 200 mm.
To carry out the test, the piece is positioned on the extension plate integrated between the two adjustment micro-cylinders.
The adjustment wheel allows you to set the distance between the cylinders according to the rope of the o-ring.
The fixing clip allows to maintain the correct positioning of curved pieces
The device is applied to the standard plate of the instrument by magnetic fixing which allows its rapid installation and removal.
Diaphragm centering device for O-rings
The device permits to perform automatic multiple tests on O-ring or round parts with external diameter between 4.5 and 75 mm. The device consist of a diaphragm to fix the external diameter of the o-ring and of a gauge-meter for the adjustment of the position of the center of the diaphragm.
The use is very simple:
1) Open the diaphragm and put the o-ring in the center of the device.
2) Close the diaphragm using the open-close leverage until the o-ring is fixed in the center of the device
3) Use the gauge-meter of adjust the position of the device according to the diameter and cross-section of the o-ring
4) Start a multiple test session to make automatically tests in different points of the sample.
To test several o-rings with the same dimensions, you only need to replace the o-ring on the device without any further regulation.
Centring Device for cylinders and Hoses
Cantering system for the measure of Micro-irhd hardness on the outer surface of rubber tubes with maximum external diameter 50 mm (other dimension on request).
No preparation of the sample to keep it flat is needed.
To perform a test, you simply need to place a piece of the hose on the device and press start.
Extension of sample holder
Extension of sample holder for Automatic Hardness tester with 300 mm diameter. The support, made of Aluminium, can be added to the standard sample holder to increase the bearing surface for the testing of big-size samples.
