Semi automatic micro - macro vickers hardness testers with auto turret and auto trigger
(10 GRAMS to 10.000 GRAMS IN ONE SINGLE TESTER)
SHT-2010 model is semi automatic, the operator turns the knob of the digital micrometer to enter a distance and then presses a key (Configurable by software) on the keyboard, the instrument moves from lens to indenter automatically, auto triggers and makes an indentation, after the indentation is made the instrument moves from indenter to lens automatically, then the operator focus and measures the indentation using the computer mouse,
All the distances are recorded in the software, the operator can see the graphics at will, the data can be exported to text files, comma-separated-values and to Microsoft Excel or to LIMS (Laboratory Information Management System)
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
- Digital micrometer: Model SHT-2010 uses a manual stage with digital micrometer combined with adjustable sample holders to make the tests
- 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
- 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 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
An additional difficulty with present method of encapsulation in plastic is that the samples are normally placed in a fixed sample holder that is attached to the stage
Finding the area of interest to test by moving the stage is time consuming and annoying, The larger the area, the more time wasted
Our solution:
In our hardness testers the holder is not attached to the stage and the operator can move it at will, on the stage and with one single point of reference all the testing can be made
- Integration with Microsoft Office: Our software is Windows based and easy to use, 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
