Spectro has been in business for nearly forty years, making analytical equipment to test metals. Although the company’s headquarters is in Germany, its operation reaches every corner of the globe.

When looking for a Spectro analytical instrument for metal testing, it pays to look at used items. Spectro’s older equipment maintains its value and is often perfectly serviceable. It can also cost about one-third as much as new metal testing equipment.

Analytical Instruments from Spectro

There are five separate used Spectro products to choose from. All of these are mobile metal analyzers. The SpectroTest line is a mobile arc spark spectrometer for jobs requiring precise metal analysis. The SpectroPort line is a smaller unit.

The SpectroTest is an arc/spark metal analyzer that allows for precision analysis. It has the widest wavelength range (174 nm – 670 nm). And it allows for sorting and identifying alloys based on certain element contents. This unit has maximum flexibility and reach. This is accomplished with 4 m (13 ft.) or 8 m (26 ft.) quick-change sample probes. These allow for a wider area of operation, and that is without any need to move the spectrometer. The unit allows for point-and-shoot analysis. Plus it is battery-powered, which allows for up to 800 measurements on a single charge.

The SpectroTest JR is a spectrometer that incorporates a diffraction grating to allow for the dispersion of light. This unit is used for the spectrochemical analysis of nonmetallic substances, metals, and fluids. The SpectroTest JR may be fitted with indicators to allow for direct reading of the analytical results.

The SpectroTest F is a mobile spark optical emission spectrometer capable of analyzing light elements in spark mode that was built for use in the shop or in the field. Arc or spark excitation is available as well as a UV probe for Carbon, Phosphorus and Sulfur analysis. The wide screen is a nice feature for easier data analysis.

The SpectroTest M is another mobile spark optical emission spectrometer that is good for Carbon, Phosphorus, and Sulfur analysis and arc or spark excitation in the field or the shop. Here is a used SpectroTest M available in good condition.

The SpectroPort is as fast as a handheld XRF, accurately analyzing elements such as Carbon, Phosphorous, Beryllium, Silicon, Magnesium, and Aluminum, even at critical and low levels. It has a self-adjusting optical system to ensure consistent results.

Spectro Service Needs

Like other optical emissions spectrometers, Spectro spectrometers require periodic maintenance and calibration. Especially with older Spectro equipment, servicing is required from time to time.

If you want to purchase a Spectro spectrometer, you will want to consider having it serviced at least once a year.


Periodic maintenance (PM) and calibration are essential tasks that you need to do on a regular basis to ensure that your equipment continues to function as intended.
