The QualiMag Series is a portable magnetic hardness tester that gets you very exact numbers on parts made of steel and iron. It uses a strong magnet to hold itself firmly to the surface you’re checking. This lets you do smooth Rockwell hardness checks that are in line with the ISO 6508 and ASTM E18 guidelines.
Put together for checking hardness right where you are, the QualiMag Series is a great fit for looking at steel plates, tubes, axles, molds, big forgings, and parts that have been treated with heat. It works especially well for checking the weld joints on boilers, tanks that are under pressure, and pipes that are under pressure. This ensures you get a material check you can count on in tough factory settings.
Unlike the usual Leeb hardness checkers, which can sometimes be less than exact, the QualiMag Series gives you consistent numbers that are very on the money. This makes it the top pick for working folks who need hardness checking they can truly depend on.
