Switchable Hardness Measuring Heads

Shore and IRHD Measuring Heads for Hardness Tester Automatic Hardness Check - Drive

Many instruments in one
The Universal Support for Automatic Hardness Testers in Drive version allows all available Shore and IRHD type heads to be applied.

Replacing measuring heads is the ideal solution for research centers with a need to measure against numerous measuring scales or for companies that predominantly use a specific measuring scale and need to carry out occasional checks against other scales.

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:
- Unscrew the locking screw
- Remove the connecting cable
- Replace the head with the desired one
- Insert the connection cable.

The instrument automatically recognizes the applied head and is immediately ready for testing.

Available Hardness Units
The Hardnedd units available are:
Shore A,
Shore D,
Shore A0,
Shore 00,
Shore AM (micro),
IRHD-Micro,
IRHD-Normal,
IRHD-Hard,
IRHD-Low.

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.
