The Affri Wiki JS Automatic Hardness Tester is a fully motorized hardness tester for Micro/Macro Vickers, Knoop, Brinell, Rockwell and even Case Hardness Depth (CHD) testing methods. It features top-of-the-line accuracy for Vickers and Knoop measurements in compliance with ASTM and ISO hardness standards, and can test single or multiple samples for Case Hardness Depth testing in an automatic cycle. Everything is automated, vastly reducing user error, and allowing the operator to focus on other tasks.
How it Works:
Just map-out indentations where required, set the load and press Start. The hardness tester then intelligently follows the predefined patterns, indents the sample, focuses when needed, measures, and generates data dynamically. Load forces are applied through load cells and electronically controlled in "Closed Loop" (Pat. AFFRI) with a frequency of 1 khz, assuring perfect linearity in every range, even on very low loads.
Motorized Head and Automatic Test Cycles
The measuring head approaches the specimen and begins the test, following every predefined pattern and performing each indentation, no matter the amount. Results are listed along with the corresponding indentation image, statistics and CHD charts.
X/Y Motorized Table
With an accuracy of +/- 0.5 μm steps, reference points for patterns indentations can be positioned precisely where they are required. The table allows automatic multi-indentation test cycles on multiple samples with perfect positioning on the entire area.
Motorized Turret
Horizontally rotating turret with four slots for magnification lenses and two for indenters. All optical microscope objectives can be pre-installed and combined with indenters for every Vickers and Knoop hardness scales.
Autofocus and Image Cleaning
With software controlled focus, image cleaning, shading correction and DC regulated light source, reproducible results are obtained regardless of the number of indents measured. From perfectly polished to rough and etched samples, the auto-detection capabilities of WIKI JS allow measurements on a variety of sample surfaces.
