Photoelectric

The photoelectric direct reading spectrometer has a wide range of applications, and is suitable for die casting, casting, metal analysis requirements in the steel or non-ferrous metal industry, inspection of incoming materials, inspection of materials, and analysis of metal materials in industries such as automobiles and machinery manufacturing. The advantages of photoelectric direct reading spectrometer are: fast analysis speed; high accuracy, relative error is about 1%; suitable for a wide wavelength range; photomultiplier tube has strong signal amplification capability, different magnifications can be used for different lines of strength and weakness The magnification can be up to 10,000 times, so it can simultaneously analyze the elements with different content ranges in the sample under the same analysis conditions; the linear range is wide, and the high content analysis can be performed. The disadvantages are: the exit slit is fixed, the elements that can be analyzed are also fixed, and the spectrum of different wavelengths can not be used for analysis; the environment is greatly affected, such as the temperature is changed, the line is easy to drift, and now the laboratory thermostat or instrument is used. Partial temperature and other measures of the optical system; expensive.

Metallographic microscope is mainly used to identify and analyze the internal structure of metal. It is an important instrument for the metallographic research of metallography. It is the key equipment for the identification of product quality in the industrial sector. It is mainly used to identify and analyze the structure of various metals and alloys. It is applied to the factory or laboratory for the quality evaluation of castings, the inspection of raw materials or the research and analysis of metallographic structure after material processing.

Metal hardness measurements were first defined by Reoum's hardness: the ability of a material to resist the intrusion of a hard object into its surface. It is one of the important performance indicators of metallic materials. Generally, the higher the hardness, the better the wear resistance.
