Shimadzu DUH-W201/DUH-211
Dynamic Ultra Micro Hardness Tester
Shimadzu Dynamic Ultra Micro Hardness Tester
The low test force (0.1~1960mN) combined with a wide indentation depth range (0.001µm~10µm) makes the DUH-W201/211 series ultra effective for performing surface hardness measurements on metals, plastics, rubbers, ceramics, and many other materials.

This instrument uniquely measures dynamic indentation depth, not the indentation after the test. This in turn permits measurement of very thin films and surface (treatment) layers that are impossible to measure with conventional methods. Additionally, this same method supplies the data needed to calculate elastic modulus on the test specimens.
     
Features  
   
  Measuring at Low Test Forces (from 0.1mN)  
  Measuring can be performed at an ultra-low test force of 0.1mN (resolution of 0.2µN) to obtain material strength properties of micro regions and extreme end sample surfaces.  
     
  Ultra-wide Test Force Range (0.1mN to 1960mN)  
  Measuring is possible between a broad test force range of 0.1mN to 1960mN to enable testing of a variety of industrial materials from rubber and plastic through to ceramics.  
     
  Indentation Depth Measuring Method Used  
  The indentation size no longer needs to be measured as just the indentation depth of the indented specimen is measured at the smallest readable unit of 0.001µm through to a maximum reading of 10µm.  
     
  Records Specimen Behavior in Indentation Process  
  The testers record the relationship between test force and indentation depth to enable a variety of data processing including indentation depth and dynamic hardness  
     
  Elastic Modulus Calculation Function  
  Calculation of the elastic modulus is possible through analysis of load/unload test results  
     
  Surface Detection Point Conversion Function  
  Surface Detection Point Conversion Function for Saved Data  
     
  Six Patterns of Test Method Possible (DUH-W201S)  
  Six pattern tests mean that not just the load process but also load/unload cyclic test, indentation depth set test and step load test, etc, are posssible.  
     
  Vickers Hardness Test Supported  
  The diagonal length of indentation can be measured. This standard function enables measurement of Vickers hardness (the hardness determined from plastic deformation only). Microscope magnification is x500 ( x1000 with option)  
     
  ASCII Data Conversion  
  The testers are equipped with a function to convert measurement data into ASCII files to enable individual development of data analysis  
     
  Easy Operation  
  The easy-to-understand mennu screens of the CRT make operation easy.

Applications
 
  Metal Materials: The hardness of micro regions with very fine and complicated structures can be reliably measured  
     
  Plastics: Hardness is an important feature of engineering plastics. Even the conventionally difficult-to-measure high light-absorption materials can now be measured  
     
  Rubbers and Elastomers: Rubber hardness measuring was conventionally performed with a uniform rubber hardness tester (JIS K6253 / ISO7619). The DUH-211 and 211S are capable of measuring at a variety of test force parameters while also being able to ascertain the hardness of top layer of rubber surface to enable evaluation of surface deterioration  
     
  Glasses and Ceramics: Brittle materials can be hardness evaluated without generating cracks. Also, the test force to generate cracks can be measured  
     
  Thin Films: The hardness evaluation of surface thin films such as coating films produced by CVD (Chemical Vapor Deposition) and PVD (Physical Vapor Deposition) or ion implanted layers has become increasingly important for the improvement and diversification of film production technology. The Ultra Micro Hardness Testers make evaluation simple  
     
  Fibers: Important data can be obtained from strength evaluation of fiber specimens contained in composite materials such as glass fiber, carbon fiber and whiskers. In addition, these testers can also handle hardness tests for optical fibers  
     
  Electronic Parts such as IC and LSI: Hardness is an important factor for the evaluation of reliability of LSI and other electronic elements. The DUH- 201 permits easy hardness testing of the desired parts of the pattern on an IC or LSI  
     
  Particulate Matter: Use of the optional flat-tip indenter provides easy measurement of particle proof stress. This data is useful for improvement of the pretreatment technique or fine particles
