A hardness tester is a precision instrument used to quantify a material’s resistance to indentation, providing critical data on mechanical properties such as strength, wear resistance, and heat treatment quality. Employed across manufacturing, metallurgy, and quality control, these testers operate on standardized scales tailored to material types: Rockwell (for metals, using diamond or steel indenters with loads from 10kgf to 150kgf), Brinell (for large samples, 10mm steel ball with 3000kgf load), Vickers (microhardness, diamond pyramid indenter for thin films), and Shore (polymers, rebound method). Modern digital testers integrate load cells with ±0.5% accuracy and optical systems (200x magnification) for automated indentation measurement, reducing operator error. Advanced models feature motorized stages for batch testing (up to 100 samples/hour) and software for data trending, ensuring compliance with standards like ASTM E18 and ISO 6508. WondersunM’s hardness testers include portable units (for on site testing of large components like turbine shafts) and bench top systems (for laboratory analysis of heat affected zones in welds). Their Rockwell testers offer closed loop load control for precise application of preload and major load, while Vickers models provide microhardness mapping to evaluate material gradients. Calibration traceable to NIST ensures measurement reliability, with annual recalibration services available globally. Supported by a team of metallurgical engineers, the company offers training on test method selection (e.g., choosing between Rockwell C and B scales for different steel hardness ranges). Exported to 100+ countries, these testers are trusted by industries from automotive (testing gear teeth hardness) to aerospace (verifying turbine blade heat treatment).
