Built by engineers who've done this before.
Arpuro Labs is the next chapter of a four-person engineering team that has been building industrial measurement systems together since 2016. Founded out of NTNU, exited a condition-monitoring business in 2020, now employee-owned and focused entirely on real-time dust.
Started at NTNU.
Signal Analysis Lab spun out of NTNU in 2016 with award funding from the Research Council of Norway. The first chapter was grid stability — analysing power-grid signals for Norwegian utilities.
Then condition monitoring.
From 2017 the team turned its signal-processing work toward rotating machinery, building a condition-monitoring system used in Norwegian industry. In 2020 the CM business was acquired by Moreld (Karsten Moholt). We delivered a two-year consultancy through 2022.
Then Elkem called.
In 2022 Elkem asked if we could measure airborne dust in real time near electric arc furnaces — something existing instruments couldn't reliably do. We launched the first Arpuro sensor in late 2024. Today it's deployed across Elkem, Boliden, Vianode and others.
Employee-owned.
In 2026 we restructured under the Arpuro Labs name. The four founders own 100% of the company. No outside investors, no quarterly pressure — just the people building the product, with our names on the patent (PCT/EP2025/052264).
A decade of putting sensors where they matter.
Four engineers. All founders. All shareholders.

Strategically located.
Our main office is at Mechatronics Innovation Lab in Grimstad — the innovation hub of Agder. Closest neighbours: the University of Agder and Morrow. We use the lab as a base for collaborations with industrial partners and universities (UiA, UiS, UiB, NTNU).
