AMHT-2010 Series

Fully automated image analysis micro vickers hardness tester with motorized stage and with operational software in Windows

(10 GRAMS to 10.000 GRAMS IN ONE SINGLE TESTER)

AMHT-2010 model is fully automatic, several lines of points can be defined, the motorized stage automatically moves to every point, makes the indentations, auto focus and auto measures by image analysis software (Mouse focusing and mouse measuring is also available when needed), then a report is presented at the end with all the graphics and the data
The data can be exported to text files, comma separated values and to Microsoft Excel

Features:

• Navas Instruments vickers hardness testers allow you to avoid the need to embed the samples in a plastic mounting, thus reducing labor and operational costs.
• Warranty: 2 Years
• Load: From 10 grams to 10 Kilograms in multiple weight combinations
• Construction: Cast iron stable construction for heavy duty durable operation
• Opening: Large opening of 135 mm allows the placement of large samples for testing
• No need of mounting: The use of large sample holders reduces sample cutting and mounting thus eliminating unnecessary costs and improving laboratory productivity
• Precision motorized stages: Stages of 25 x 25 mm or 100 x 100 mm travel ranges, all of which support large sample weights
• Illumination: Simple "straight through" illumination and optical system eliminating alignment problems and high power lighting
• L.E.D Light: Very reliable, very low heat emission, No need of maintenance, long working life
• Optics: Long working distance objective with three position zoom and straight optics, providing superior image quality with magnifications of 100X, 200X and 400X
• Image analysis: Automated measurement with auto focusing of indentations which enables accurate results and automatic operation, All models support also mouse focusing and mouse measuring when needed
• Lineal turret: The lens-to-indenter and indenter-to-lens movement is automatic for measurement accuracy
• Easy to use: Easy to use Windows based operational software
• Data export: Powerful Open Data Base Connectivity, data export to text files, comma separated values, to Microsoft Excel and to LIMS (Laboratory Information Management Systems)

Tests:

Determination of: Vickers hardness in metal parts in the automobile industry, avionics, heat treating and other applications

Applications:

Vickers hardness measurement in constant velocity ( CV joints ) , crank shafts, gear boxes, traverse applications, etc...

Advantages and benefits:

• Robust design: We manufacture our own motorized stages, hardness testers, electronics and software
  Unlike many other brands of hardness testers that are assembled from another company's components
  We make hardness testers with simple and robust construction
  
  
• Save time and money: Navas Instruments hardness testers will save you money and time
  
  The problem: It is well known to the metallurgical lab the high cost in labor, time and consumables involved in preparing samples for hardness testing primarily when the parts have large heated areas basically by induction heat treating process
  This high cost and time consuming process drives laboratories to decrease testing and therefore is an increased risk of part failure
  
  Cost is related to the present method (encapsulating the samples in plastic mounting) used to prepare the samples for hardness testing
  When mounting in plastic the samples have to be reduced to the available plastic molds therefore huge cutting work may be necessary for large parts, cost is very high in cutting disks with all the labor involved in mounting the samples in plastic, polishing several samples for one single job and doing Vickers testing in several samples for one single part tested with the test data in several files
  
  An additional difficulty with present method of encapsulation in plastic and testing automatically is that the samples are normally placed in a fixed sample holder that is attached to the motorized stage
  Finding the area of interest to test by moving the motorized stage is time consuming and annoying, The larger the area, the more time wasted
  Locating the areas of interest to be tested by image analysis is also time consuming, Testing time is lost searching for the location to test
  
  Our solution: In our hardness testers the holder is not attached to the stage and the operator can move it at will, on the motorized stage and with one single point of reference all the testing can be made
  The software works similar to a universal measuring machine, all the distances are previously stored for all the parts, the stage will move to the areas of interest automatically
  
  
• Integration with Microsoft Office: Our hardness testers provide the vickers values and other data: graphs with distances, X and Y coordinates, dimensions of the indentations, etc ...
  The data can be printed and exported to text files, comma separated values and XLS files to be imported in Microsoft Excel or several LIMS (Laboratory Information Management Systems)
  Data is stored in a powerful Open Data Base Connectivity Database (ODBC) in Microsoft Access format

Software features:

• Our software is Windows based and easy to use
• The operator creates a file with the coordinates to make the indentations, the operator then saves the file to disk and makes a testing
• The motorized stage moves to the defined points and makes the indentations
• Then the indentations are auto-focused and measured automatically by image analysis
• The operator can recover the stored file on disk with all the coordinates and data, the operator can create any number of files with any number of indentations and coordinates
• After the testing the software shows a report with all the graphics and data, the generated report can also be printed, saved to a disk file and exported to text files, comma separated values and XLS files for use in Microsoft Excel or other spread sheets
