Manual Centring Devices for Micro IRHD tester
The Micro-IRHD tester is designed to carry out tests even on very small finished pieces. Centring devices are useful for positioning the test-piece under the indentor.



Overview 
The device is used in combination
with the Micrometric Slide (code 8-HS0-44-000-0) and enables automatic multiple tests to be carried out on O-ring or round parts with external diameter up to 75 mm.
The use is very simple:
1) set on the manual gauge-meter of the sliding system the dimension of the o-ring to be tested (int. diam + cord)/2 to centre it correctly.
2) put the o-ring on the Diaphragm
centring and fix the o-ring slightly
using the open-close leverage
3) start a multiple test session to
make automatically tests in different points of the sample.
When you test different o-rings of the same kind, no regulation is required between one o-ring and the next one
The distance between the plate and
the diaphragm can be adjusted according to the cross-section of the o-ring.
The Y axe position is automatically
centred due to the mechanical construction of the instrument.


 
The device is designed for the quick
centring of O-rings or cylindrical
parts independently from the diameter. This device permits to make one test on the sample and requires manual repositioning of the sample between one tests and the next.
This device is mounted directly on the standard plate of the instrument.
The use is very simple:
1) the sample is placed between the
vertical micro-cylinders.
2) the position of the micro-cylinders is regulated using the handle to fix the sample in the middle.
3) the middle position of the micro-cylinders is the correct centring
point for the test.
The height of the micro-cylinders can
be adjusted using the regulation
ring according to the cross-section
of the sample.
The Y axe position is automatically
centred due to the mechanical construction of the instrument.


 
A piece of tube is placed on the horizontal cylinder for testing.
Note: this device requires manual
repositioning of the sample between one tests and the next.




 
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.


Diaphragm centering device 
Enables Multiple Automatic testing of o-rings or round parts with external diameter up to 75 mm.
Testing of samples with the same dimensions don't require re-centring.
Distance between support plate and diaphragm is regulable to fit sample section 
Microcylinder centering device 
Permits quick positioning of symmetric parts without diameter limitation
Manual positioning is required between one test and the next
The height of the micro-cylinders can be adjusted according to the cross-section of the sample 
Centering device for tubes 
Permits to test rubber tubes with external diameter up to 50 mm
Manual positioning is required between one test and the next
