GOYOJO Portable Leeb Hardness Tester -,Hardness Testing Equipment Kit with Test Block, Copper, 7-in-1 HL, HV, HB, HRC, HRB, HRA, HS

Tested it on my hunting knives and it worked perfectly. Readings were fast, consistent and accurate. The 7-in-1 conversions are super handy and the included test block makes calibration easy. Great quality kit - highly recommend!

I have calibration blocks and the values ​​this instrument measures are within tolerance. Good value for money.

Portable, easy to use and affordable. If you need to take measurements on site, especially for large or stationary components, this device can make the task much easier. Measures at different angles. It is necessary to calibrate it, don't forget about it.

Defective... More cheap garbage that doesnt work being sold on Amazon.

En las fotografías de publicidad tría la descarga de datos, pero es incorrecto. Escribí al fabricante y me dicen que ninguno de sus modelos tiene esta posibilidad. Por el precio pagado esta bien el equipo aunque su memoria es poco confiable ya que se puede acceder facilmente a los primeros y últimos 10 grupos de datos pero a datos intermedios resulta confuso. Relación calidad precio es buena.

This portable hardness tester is very convenient and useful. It’s light, small and supports seven different hardness scales, it is good for working with different hardness materials. I think it is a good choose for professionals who need quality and reliability

A good unit and does the job right! Highly recommend.
