Micro IRHD Laser Revolution
Micro-IRHD Hardness tester with laser centring device and rotating sample holder for the automatic serial measure of O-ring and small rubber parts


Standards the instrument complies with:   
ASTM D1414;   ASTM D1415;   FIAT 50408;   ISO 48;    

Description 
The instruments is supplied with laser centring device and motor-controlled sample holding disk for the displacement of the parts to be measured.
The sample holding disk moves each test piece under the laser centring tool and then places the optimal test point of the part under the micro-irhd testing unit.
The positioning and hardness measuring operations are performed automatically for all the parts placed on the sample holding disk across the laser reading line without intervention of the operator.

Reference Standards 
The instrument is conforming to ISO 48, ASTM 1415, DIN 53 519-1/2 standards.

Applications of the instrument 
The instrument permits to perform the serial measure of micro-irhd hardness of O-rings and small parts eliminating the human influence in the sample positioning.
The instrument is useful for:
- Product approval or Quality Control tests which require the repeating of the tests on statistical basis
- Mold approval tests
- Process capability analysis
- Testing of small parts difficult to be centered manually
O-rings or small parts with a thickness between 1 and 20 mm can be tested.
The laser testing process can be stopped to perform tests with standard samples.



Accredia Calibration of the instrument 
The instrument is available with ACCREDIA calibration certificate. The certificate is issued by Gibitre ISO 17025 Accredited laboratory.

Standard Calibration service for IRHD Hardness Tester 
The calibration is performed with reference to the requirements of ISO 48 standard.
The service includes:
• Ordinaly 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 apllication 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.


Use of the Instrument 
To perform the test you simply need to:
- place the parts to be tested across the test line of the sample holding disk
- insert the identification of the product
- press start
- print the test report and save the test results when the complete rotation of the disk has been performed and all the samples have been tested.




Measure of micro-irhd hardness on pieces with non-symmetrical shape  
The software for the control of the instrument includes a ‘Scan’ function which permits to record the laser reading of the profile of a piece and to define the position where the test has to be made.
The test setup for each product is stored and is automatically re-used when the same product is tested again.


Execution of tests on different products 
The sample-holding disk is divided in 4 sectors.
According to your needs, you can use all the sectors to test the same product or you can place different kind of pieces in each sector. At the beginning of the test you can enter the identification for the products placed in each sector. In this way each result will be saved and printed with correct identification.

Test results produced 
The instrument calculates automatically:
- Micro-IRHD Hardness
- Thickness of the sample in the test point
- Angle coefficient of the hardness relaxation curve
- Hysteresis curve
- Corrected hardness (the hardness of test pieces with non-standard thickness is corrected according to the method described in UNI 7319 to estimate the expected hardness of a sample with 2 mm thickness)



Comparison with Tolerance limits and statistic analysis 
The software for the control of the instrument permits to set tolerance limits for each product. The conformity of each result is automatically checked at the end of each test.
The statistic analysis of the ongoing tests includes: X-Chart, Gaussian Di- stribution , Max, Min, Mean, Standard Deviation, Cp and Cpk.


Storage and traceability of test results 
The software permits to store all test results in a database with SQL structure.
For each test the following information is stored: Order, Lot, batch, sample, Customer, Product, ageing treatment, executor of the test, date, hour, serial number of the instrument, test procedure, numerical test results, test curve, conformity with tolerance limits.
The database management program permits to select the results in order to make comparisons, statistics and to produce customized test reports.

Test Report 
The test report can be produced in one of the languages installed.
The report includes the test results and the test identification information. In addition it may include the test curves, tolerance limits, statistic analysis, a legend with the description of the calculated results, the signature of the software user and eventual notes.




Software Characteristics and connection to the PC 
The software is compatible with Windows 7 and 8 (32 and 64 bits).
The connection of the instrument to the pc is made via USB cable (supplied with the instrument)
More instruments can be connected to the same PC and used at the same time.


Technology of Micro-IRHD device  
The micro-irhd testing units produced by Gibitre measure the force applied to the sample using a load cell.
This technology, widely used for the hardness testers for metals, permits to eliminate the effect of friction in the application of the force and improves the test repeatability.


Characteristics of the laser centering device and of the sample-positioning system 
The laser sensor used is class 2 type and has 0.002 mm reading resolution.
The sample positioning disk permits to set the position of the test piece with 0.005 mm accuracy.
The combination of accurate measuring and sample positioning devices ensures a very high repeatability of the results obtained even when very small parts are tested.



Modular Construction 
The main parts of the instrument are: the measuring unit, the sample displacement system and the electronic card.
Those parts have been developed to permit quick and independent replacement in case of failure. This characteristic ensures short recovery time and low maintenance cost.

Safety devices 
The instrument includes safety devices to eliminate potential risks during the automatic working.
- Test stops in case of incorrect sample centring
- Test stops in case of overload of the indentor
- Test stops in case of missing laser reading or sample positioning reading.


 



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.
The automatic logging service permits to send alarm information to the cloud-service platform of Gibitre Instruments in order to optimize the reaction times of the Service Support.
