Micro Duro Meter
Hardness Tester |
MICRO DUROMETER, MD-1
For Hardness Measurement and Control
of Small and Thin Specimen made of various Rubber Materials,
Thermoplastic Elastomers, Soft Plastics and etc.
|
|
Introduction:
- As recent technology requires more
micronized products, it would be not applicable to such requirements
with conventional hardness tester for rubber.
- Micro Durometer Model MD-1 is developed
to fill such demands for quality control of micronized measuring
objects enabling high accuracy by easy operation.
- MD-1 enables measurement of hardness
of thin and small objects that can not be measured with conventional
rubber hardness tester.
- Designed and manufactured as the 1/5
reduction model of spring type rubber hardness tester (Durometer)
A-type and the measured value is approximately comparable with
A-type Hardness of ISO 868 or ASTM D 2240.
Main
Features:
- Applicable to various samples such
as small and thin rubber parts or sheet in about 1mm thickness
up to 60mm height.
- Simple preparation and easy adjustment
as well as easy setting of sample.
- All measurement actions are automatic.
Just press a switch and wait for a few seconds, the data is indicated
and printed automatically.
- Automatic test by one-touch key operation
and eliminate operators' personal errors in data.
- The measured value is approximately
comparable with ISO 868 and ASTM D 2240 A.
- Selection of [NORMAL], [PEAK HOLD]
or [TIMER HOLD] as standard.
- Pressure speed of sensor against specimen
can be kept constant by air-damper control.
- Possible to connect with other equipment
(P.C. etc.).

Example
of Measuring Objects:
- Sealing parts as packing, '0'-ring, gasket etc.
- Automobile parts as bushing, coupling, weather strips etc.
- Precision rubber parts for electric articles of automobile.
- Motive and transferring rubber belt such as timing belt, conveyer
belt etc.
- Medical rubber cap, tube etc.
- Precision rolls for office machines as facsimile machine, printer,
copy machine etc.
- Precision rubber parts for electric appliance.
- Natural and synthetic rubber materials (for development and
research).
- Rubber sheet for shoes.
- Test piece for various standard (ISO, ASTM, DIN, JIS etc.).
- Any other small and thin rubber parts.
Advantages
of MD-1:
- Easy Operation: Just put sample
on the table, adjust the sample position and push MEASURE switch
for automatic measurement.
- Wide Space: Having wide space
for sample, various kind of samples can be measured.
- Quick Measurement: Thickness
of sample: 1mm-60mm About 3 seconds for one cycle automatic measurement.
(7-8 seconds for a few points measurements)
- Multi-Point: Equipped with X-Y
cross table with micro adjustment, you can remove sample in 1/100mm
step. Measurement of multiple points is quite easy.
- Free from Operator's Error:
Automatic measurement eliminates operators' errors and the data
is always reliable.
- Maintenance Free: Simple mechanism
and precisely finished parts enables maintenance free.
- International Standard: Approximately
comparable with ISO 868 and ASTM D 2240 A.
