Overview
Automatic hardness testers with digital diplay are a control solution that does not require any type of installation:
simply remove the instrument from the packaging and connect it to the power supply.
The instrument allows you to:
• move the specimen automatically eliminating the influence of the operator on the measurement
• perform the tests immediately by pressing the Start button only.
At the end of the test, the measurement result is shown on the display.
These tools are ideal when testing is needed at any time and data storage is not required
Touch-Screen Display
The Display permits to set the test time and to start the execution of the test.
The hardness reading is displayed at the end of the test time.
Available Hardness Scales
Available hardness scales are:
Shore A,
Shore D,
Shore A0,
Shore 00,
IRHD-Micro,
IRHD-Normal,
IRHD-Hard,
IRHD-Low.
Accredia Calibration of the instrument
Gibitre Instruments is Accredited Accredia laboratory according to ISO 17025 Standard
The instrument can be supplied with an ACCREDIA calibration certificate issued by the Accredia laboratory of Gibitre instruments.
The calibration is carried out according to the Technical Procedure approved by Accredia and in compliance with the requirements of the ISO 48-2 (IRHD), ISO 48-4 (Shore A) and ISO 868 (Shore D) standards.
The Calibration refers to:
• Dimensions of the Indentor and Annular foot
• Forces applied by the indentor and the annular foot
• Displacement of the indenter
• Duration of the test
Standard Calibration service for IRHD Hardness Tester
The calibration is performed with reference to the requirements of ISO 48-2 standard.
The service includes:
• Ordinary maintenance of the instrument
• Visual inspection of the Indentor.
• Calibration of the Pre-Load, of the Main Load and of the weight of the Anular foot.
• Calibration of the force application time for Pre-Load and Main-Load (NEW)
• Calibration of the displacement of the indentor in correspondence with several IRHD Hardness readings
• Pre-calibration and Post-Calibration test of the instrument with reference test samples (NEW)
• Issue and e-mail shipment of the Calibration Certificate with traceability to primary standards.

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.
Automatic Sample displacement
The motorized ascent and descent movement of the specimen allows the test to be carried out automatically.
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.
Development and production
The instrument is totally developed and produced in the plant of Gibitre Instruments in Italy.
All the mechanical parts are produced in the company workshop using modern CNC machines.
Components and sensors from well-known brands are selected in order to ensure the maximum reliability in the measures
Internal trained personnel takes care of all the production stages: assembly, start-up, calibration, packing, shipment and installation.
