Standard Full Load Melt Flow Index Measurement 1 Year Warranty

Manual Automatic Full Load Melt Flow Index Measurement With 220V ± 10% 50HZ 1 Year Warranty

Introduction:

Plastic ball indentation hardness tester is in refers to the regulation of the diameter of the steel ball, under the influence of load test, vertical pressure into the surface of the sample and keep a certain time on unit area of indentation on the average pressure tester.
Developed by our company plastic ball indentation hardness tester, using automatic acquisition methods such as loading, choice of timing, deformation, and eliminated the widespread adoption of digital display mode, and adopts touch screen display. In this way, the operator after the boot can be according to the characters on the LCD screen prompts for test operation, great convenience to the user. Plastic ball indentation hardness instrument parameters conform to GB3398.1-08, GB3398.2-08, ISO2039 1:20-01, ISO2039 - "01 and relevant provisions of the standard.
Can achieve a plastic ball indentation hardness and plastic Rockwell hardness of two kinds of test method test.

Operating principle:

According to the standard requirements, in the frame, loading device, indentation depth indicating device, timing device and pressure head (regulation of the diameter of the steel ball are embedded) of institutions, by loading device in a given test load down head vertical pressure into the surface of the sample, keep a certain time of the average pressure on unit area of indentation. KGF/was or N/was said.
The ball indentation hardness value press type calculation:

           0．21P

 H=------------------------

        25πD(h-0.04)

In the formula::H - ball indentation hardness,kgf/mm2 and N/ mm2

P——Test load,kgf or N；

D——Steel ball diameter,mm；

h——After correction frame deformation of indentation depth,mm.

Annotation:h=h1-h2;

h1——Under the test load pressure depth,mm；

h2——Equipment under test load frame deformation,mm

The main configuration and accessories:

One set host

Host head(Ф6.35mm；Ф5mm；Ф12.7mm；Ф10mm；Ф3.175mm)

A mini printer and one manual
