产品特点

产品本体部分采用铸造工艺成型，并经过长时间处理。与跳汰工艺相比, 长期使用形状变量很小, 并能有效适应各种恶劣环境;

汽车漆, 高品质油漆, 耐刮擦能力强, 使用多年依然光亮如新;

Small test force, left indentation small, do not affect the specimen to continue to use;

The dial directly reads, and can be selected with the surface of other rulers;

The lever and load, with the frictionless main shaft, the test force precision is high;

Through the motor to control the loading, loading and unloading of the test force, the manual operation error of manual lowe is eliminated.

The accuracy is in accordance with GB/T230.2, iso6508-2 and ASTM E18.

 

适用范围

Surface quenching steel, 铜, aluminum alloy sheet, strip steel, hard alloy steel;

Zinc plating, chromium plating, tin plating, material surface heat treatment and chemical surface treatment of various metal materials.
