The Indentron® Series hardness testers feature an innovative cantilevered indenter configuration that eliminates frictional inconsistencies typical of competitive testing systems. These systems comply with ASTM E-18. Using precision dead weights, the INDENTRON system ensures precise, accurate and repeatable measurements. The dead weights are used for both the major load and the preload. Automation in the timing, reduces the variation introduced by the flow of the material under load. If the operator inadvertently over loads or under loads the preload, the INDENTRON system prevents the test from being performed. 

The indenter design is ideal for testing inside diameters and recesses, often impossible with more traditional hardness testers. Inside diameters as small as 1-1/2-inches can be tested with the standard indenter. Optional indenters can test diameters as small as 1/2-inch. Operators can test close to vertical surfaces, to within 1/4-inch with the standard indenter and up to 3/32-inch with optional special indenters. Testing is fast, accurate and there are fewer broken diamonds due to an outstanding viewing area. 

Two models of the Indentron Series are available- the basic 300 Series and the advanced 400 Series. Both models can be supplied for Regular, Superficial or combination testing methods. 

The Indentron 400 Series features our advanced digital electronics and display panel. Averaging of 2-99 tests, hardness cale conversion, round correction, minimum thickness, time at load are advanced features supplied standard on the 400 Series. The system can store up to 5000 test results in memory and produce statistical computations. An RS232 output can be used to produce X-Bar/R Charts, histograms or integrate to a personal computer with our DataView application software for more detailed analysis. Tolerances may be applied for Pass/Fail or Go/No Go results. 

The Indentron 300 Series uses our basic digital electronics and display panel. Averaging of 2-9 tests with tolerance indication can be achieved. Basic printing of statistics include Average, Range, Min/Max, Standard Deviation, CPK, as wall as the number and percent Hi/Lo based on a user-defined HI/Lo tolerance. 
 

Features & Benefits

• Virtually Friction-Free Operation
  The only contact points in the load system are a set of bearings at the end of the lever beam carrying the major load and a leaf spring at the end of the lever beam carrying the minor load.
• Dead Weights for Full Load and Preload 
  Most competitive testers use dead weights for the full load due to their accuracy, but use springs to apply the preload. Dead weights are used on the INDENTRON Series for both full load and preload due to their excellent accuracy and stability under a wide range of conditions.
• Full Load Is Applied Precisely at Preload 
  Automation in the timing reduces the variations introduced by the flow of the material under load.
• Preload Error Monitoring 
  The system prevent the operator for completing a test if the preload is over- or under-applied. ead Weights for Full Load and Preload ead Weights for Full Load and Preload Most competitive testers use dead weights for the full load due to their accuracy, but use springs to apply the preload.
