Bote BH900 portable digital color screen Leeb hardness tester

1、 Product Overview:

BH90 Leeb hardness tester is a hardness measuring instrument; Its principle is based on the impact of a certain mass on the surface of a sample at a certain height, measuring the impact velocity and rebound velocity at a distance of 1mm from the sample surface. Using the principle of electromagnetic induction, the velocity is converted into a voltage signal, and the Leeb hardness value is calculated. Measurement materials include: steel and cast steel, alloy tool steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper zinc alloy (brass), copper tin alloy (bronze), pure copper, forged steel, etc; Widely used in industries such as mechanical processing, aerospace, automobile manufacturing, metallurgical industry, rail transit, mold casting, university research, pressure pipelines, and special equipment testing; The Leeb hardness tester has the characteristics of small size, light weight, easy portability, and simple operation, and can perform hardness testing on large workpieces on site.
