The OE720 Metals Analyzer from Hitachi

Hitachi’s OE720 optical emission spectrometer (OES) metals analyzer is an innovative instrument that covers the entire spectrum of elements in metals* using advanced multi-CMOS technology and low detection limits.

Complex supply chains, rigorous industry regulations and the growing use of scrap as a base material make it significant for metals manufacturers and foundries to regulate residual, main, tramp and trace elements in the lowest ppm range. Traditionally, OES analysis at this level was beyond the reach for several businesses but this situation is now changed with OE range from Hitachi.

With the OE720 spark spectrometer, users can now examine all main alloying elements and detect very low levels of trace, tramp and treatment elements in metals.

Low operating costs, high reliability and rapid measurement times make the OE720 analyzer useful for day-to-day analysis and complete quality control, delivering performance equivalent to larger and costlier spectrometers.

Why Select the OE720?

High performance made affordable: Except for gases such as hydrogen and oxygen, the OE720 OES spectrometer spans the entire spectrum of elements in metals and features some of the lowest detection limits in its range.

The outcome is an analyzer that has the potential of relatively costlier instruments and thus brings high quality analysis within reach for several metals manufacturers and foundries, for the first time.

Novel technology: The superior performance of the Hitachi OE range is attributed to its special LightWing optic design**, combined with advanced CMOS detector technology.

This exclusive combination obtained the extremely large wavelength range required to quantify the whole range of elements in metals in the lowest ppm levels. This is crucial for fulfilling present rigorous metals specifications.

Low cost of ownership: Another benefit of the LightWing optics is reduced consumption of argon and power because of its ultra-compact design. In addition to allowing a rapid start-up and measurement time, the LightWing optics reduces costs and boosts productivity.

Developed for the aluminum industry: The OE720 is the perfect analyzer meant for aluminum casting because it can detect phosphorous to exceptionally low limits in near hypereutectic and eutectic aluminum-silicon alloys.

The system can analyze sodium, strontium, lithium and antimony, bismuth and tramp and trace elements, and makes sure that all these elements are controlled within the aluminum melt for improved structural modification. This supports high throughput production, where the melt quality needs to be checked at many points.

Easier and faster analysis with comprehensive software: Apart from the novel hardware technology, the performance of the new OE720 analyzer is also improved by new, advanced software. Thanks to the intuitive SpArcfire operating software, OES analysis is made fast and simple.

The OE720 analyzer includes the Hitachi GRADE Database that provides over 15 million records for more than 340,000 materials from 74 nations and standards, thereby decreasing time and possible errors that occur from manually consulting grade catalogs.

The charge correction software, which is provided as an option, automatically estimates the exact amount of material to add to a melt to bring it into specification. With ExTOPE Connect wireless technology, manufacturers can collect live data for real-time decision-making even across numerous lines, locations and production stages.

Excellent price-performance ratio: The OE720 analyzer offers a perfect solution to customers who do not have to check the gases in metals but do not want to compromise on the analytical performance. The OE720 provides complete metals analysis in a single accessible package.
