Who we are


SP3H is a technology-oriented company that develops clean technologies and smart solutions for process industries and transportation markets. The company offers a range of products called «  »FluidBOX » based on Near Infrared technology. Our FluidBOX product is able to identify in real time and continuously the quality of most organic fluids, online and on-board vehicles. The team includes talented people who have designed a new generation of disruptive scanners by combining their expertise in spectroscopy, optronics and mechanical design, chemometrics, data processing, smart data and advanced modeling and predictive algorithms.

What we do

SP3H is building a sustainable future for all. Our FluidBOX scanners, affordable and intuitive, are fully compliant with harsh environments and provide detailed data regarding the molecular structure of organic fluids. This information enables our technology to drastically reduce the carbon footprint of major Industries (refining, petrochemical, chemical…) thanks to real time process optimization. Combined with the growth of renewable and synthetic biofuels, FluidBOX sensors make it possible to optimize thermal engines and reduce CO2 and pollutant emissions in the automotive sectors, transportation market (road, non-road, farming, aerospace, rail) and power generation industry (gensets).
