Measuring range: 0 ~ 250mm It can measure the shape of the plain wire, straightness, angle, crown, logarithmic curve, groove depth and groove width of various precision mechanical parts.

Measuring range: 0 ~ 150mm

It can measure the shape of the plain wire, straightness, angle, crown,

logarithmic curve, groove depth and groove width of various precision

mechanical parts.

The instrument is suitable for use in the field of two-dimensional planar

measurement. Mainly measuring machinery, molds, precision hardware,

precision stamping, gears, cams, threads, bearings, etc.

It is mainly used to measure the metallographic structure of products after

heat treatment such as spheroidized structure, quenched structure, tempered structure, troostite and the like.

The digital Rockwell hardness tester is a mechatronics hardness tester, which is controlled by a microcomputer and the hardness value is directly displayed by numbers. In addition to the test bench lift, automation is fully automated, eliminating operational and reading errors. The hardness tester is suitable for the hardness measurement of ferrous, non-ferrous and non-metallic

materials.

The Vickers hardness tester is mainly used to test the hardness of small

precision parts, the hardness of the hardfacing layer and the depth of the effective hardened layer, and the surface hardness of the coating.

The equipment is suitable for the bearing manufacturing industry to detect

the cracks formed by the quenching and grinding of the raw material of the bearing ring. Compared with the magnetic particle flaw detector, it has the

advantages of high automation, fast detection speed, convenient inspection process and no influence by unmanned factors.

The portable three gas calculates the carbon potential by detecting carbon monoxide, carbon dioxide and methane in the atmosphere of the furnace,

thereby achieving the purpose of controlling the carbon potential in the

furnace.
