Hardness Measuring Heads
Shore and IRHD Measuring Heads for Hardness Tester Automatic Hardness Check - Drive
With the new generation of Drive Automatic Hardness Testers from Gibitre Instruments, tailor the instrument to your measurement needs. The interchangeable head system lets you swap Shore and IRHD heads on the motorized stand in seconds; the rigid quick coupling preserves perfect perpendicularity, a prerequisite for reliable results on your materials. This versatility suits labs that work across multiple measurement scales without multiplying tools: one hardness tester covers diverse needs, streamlining workflows and cutting setup time between tests.
All measuring heads comply with ISO 48-2, ISO 48-4, ASTM D2240, and ASTM D1415.
Why choose the Drive Automatic Hardness Check? It grows with you: additional heads can be added after purchase, expanding your lab’s measurement capabilities as new requirements emerge and safeguarding your investment. The Drive version’s configurability and rapid head change help you respond quickly to varying demands while maintaining continuity. In short, a
Your Testing Needs
Do you need to test different products according to a specific hardness scale?
Do you need to evaluate incoming compounds and finished parts across multiple scales?
Do you require the flexibility to switch between various hardness scales without notice?
Whatever your needs, we offer the ideal setup to meet your requirements.
Versatility in One Instrument
The Universal Support for Automatic Hardness Testers in the Drive version accommodates all available Shore, IRHD, and VLRH hardness units. Swapping measuring heads offers a versatile solution for research centers or labs that require measurements across various scales, as well as for companies that primarily use one scale but need occasional checks against others.
Complete Hardness Testing for Simultaneous Use
For companies conducting systematic production checks using different measurement scales (e.g., Shore A and Micro-IRHD), dedicated hardness units for each required scale are essential. The optimal setup, based on our experience, involves installing independent hardness testers connected to the same PC. This configuration allows multiple operators to use the instruments simultaneously without any interruptions.
Many instruments in one
The solid quick coupling system allows the head to be replaced in seconds while ensuring its perfect pependicularity with respect to the support base.
To replace the measuring head:
- Remove the connecting cable
- Unscrew the locking screw
- Replace the head with the desired one
- Screw the locking screw
- Insert the connection cable
The instrument automatically recognizes the applied head and is immediately ready for testing.

Complete hardness testers for simultaneous use
For companies that need to perform systematic production checks against several different measurement scales (e.g., Shore A and Micro-IRHD), it is necessary for durometers to be available at the same time to perform measurements at the required scale.
The optimal solution we propose for such cases is the installation of multiple complete hardness testers connected to the same PC with a single software license. In this way the instruments can be used simultaneously and by several operators without any interruption.
Automatic performance of multiple tests on the sample
International standards require the performance of multiple hardness tests on the specimen and the calculation of the median value.
• The specimen holder plate with motorized rotation allows multiple tests to be performed automatically at different points on the specimen.
• The operator can set the number of tests to be performed automatically on the specimen and the angle of rotation between successive tests.
Accredia Calibration of the hardness units
Each Hardness Unit 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
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.
