HX-750 (PMT) photoelectric direct reading spectrometer
Overview: HX-750 (PMT) photomultiplier tube (PMT) photoelectric direct reading spectrometer gathers the proven mature and effective spectroscopic analysis technology for decades at home and abroad. For the analysis of solid metal samples, the spectrometer using photomultiplier tube technology has the right spectrum The information is characterized by high sensitivity, high accuracy and long service life. According to the analysis needs of users, it can add analysis channels and analysis substrates for users; it can also add factory calibration curves for users, or users can use their own standard samples to establish analysis curves, which can meet various user requirements. HX-750 (PMT) photoelectric direct reading spectrometer is a fast, accurate and quantitative analysis instrument for the chemical element composition in ferrous metals and non-ferrous metals (iron-based, aluminum-based, copper-based, nickel-based, etc.) materials. It is widely used in metallurgy, machinery, casting, metal, scientific research and other fields. Online analysis in front of the smelting furnace and product inspection in the central laboratory are one of the effective means to control product quality. Technical Parameters: 1.
