S3 MiniLab 300
Ultra Compact Optical Emission Spectrometer
Ultra-compact CMOS-based spark OES with an extended 130–700 nm range for ferrous and non-ferrous alloys, including foundry use.

About the S3 MiniLab 300
S3 MiniLab 300 is the newest Spark Emission Spectrometer designed by GNR to celebrate its 30th year of operations.
Nowadays MiniLab series are ones of the smallest and lightest compact optical emission spectrometers available on the market with outstanding analytical results in this category.
S3 MiniLab 300 offers an excellent solution for metal analysis: it combines easiness of use, low maintenance cost, affordable price with the most advanced technological optical and electronical components, ensuring complete spectral coverage at best resolution and light efficiency.
In 2017, our engineers have designed the 2nd generation model which make the S3 MiniLab 300 system fully suitable not only for general purpose applications but also for more demanding and heavy duty applications.
S3 can cover almost all the analytical requirementrs of a modern foundry but not only.
The innovative argon purged optic, with an argon consumption of 10 l/day only, ensures the maximum light transparency even in UV region at negligibile costs.
The result is a completely new CMOS based instrument with the possibility to analyze the following matrices (Iron, Copper, Aluminium, Nickel, Zinc, Tin, Titanium, Cobalt, Lead, Magnesium) with superior analytical performances.
