1. Overview:
MH180 portable Leeb hardness tester is based on the Leeb hardness measurement principle, which can measure a variety of metal materials conveniently and quickly. While displaying the hardness measurement value immediately, it can freely switch between different hardness systems, with stable performance and price Affordable. It is a practical and cost-effective hardness tester promoted by Mattel.
