Hitachi OE Series Optical Emission Spectrometers (OES)

More info about product

The OE750 and the new OE720 are revolutionary optical emission spectroscopy (OES) metals analyzers that provide comprehensive elemental analysis across the full spectrum of metals. Utilizing state-of-the-art multi-CMOS technology, these analyzers offer low detection limits, allowing precise measurement of main, residual, tramp, and trace elements down to the lowest parts per million (ppm) range. This capability is increasingly critical in today’s metalworking industry, where tightening regulations, complex supply chains, and the growing use of scrap materials demand rigorous control over elemental composition. These spark spectrometers are designed to deliver high performance and reliability, enabling the analysis of all main alloying elements and the detection of exceptionally low levels of tramp, trace, and treatment elements, such as nitrogen in steel. The OE750 also supports rare applications, including the measurement of oxygen in copper and the analysis of oxygen, nitrogen, and hydrogen in titanium. With fast measurement times, high reliability, and low operating costs, the OE series is ideal for everyday analysis and comprehensive quality control. These analyzers provide performance comparable to larger, more expensive spectrometers, making them an invaluable tool for foundries and metals manufacturers looking to ensure the highest standards of product quality.
