Setnag

What Setnag does

Setnag is a French designer and manufacturer of oxygen analysers used to measure and control gases in combustion, industrial processes, and fundamental research. Founded in 2000 and headquartered in Marseille, the company operates at small scale (11-50 employees) and has been ISO 9001 accredited since January 2000. It serves industrial and scientific end markets including power and energy production, chemical and petrochemical processing, waste incineration, food and beverage, control laboratories, and academic/government research institutions.

The company's portfolio is built around its proprietary MicroPoas® technology — a miniaturized zirconia-based oxygen sensor (standard 3mm diameter, 10mm length) with a built-in metal reference that eliminates the need for reference gas, incorporates a built-in thermocouple for temperature compensation, and operates under extreme conditions (500-1050°C, vacuum to over 70 bar, response time under one second, and a lifespan exceeding three years on clean gases). This sensor is the foundation for a family of finished analysers: combustion/incineration gas analysers (ATK/F-EUT, OXYBOX'ATK, ATS/D EUT) rated for continuous operation up to 1300°C; process analysers (TTH, JC range, S24N-EUT, LISO/P, LISO/F, OXYBOX'AIR + S24N-EUT); oxygen pump gauges (GEN'AIR with automation module); and partial-pressure instruments (JOK'AIR, OXYBOX'ATM). The ATK/F-EUT is pursuing TUV QAL1 certification (EN15267-3, range 0.1 to 25%).

Setnag operates a hardware manufacturing business model centered on 100% French production, selling analysers, sensors, and spare parts to enterprise industrial buyers. Go-to-market is a mix of direct sales from its Marseille headquarters and an international distributor network, with lead generation via its corporate website and technical documentation and conversion through direct phone/email contact. Pricing is not publicly disclosed and is quote-based. Reference customers include Air Liquide, Linde, EDF, ArcelorMittal, Sanofi, Solvay, Nestlé, Heineken, CNIM, TREDI–Seche Group, E2 (Dong Energy), THERMOELECTRICA Romania, and research bodies such as CEA & CNRS, Université Libre de Bruxelles, and the Paul Scherrer Institute.

Core offering

Setnag designs and manufactures oxygen analyzers and sensors based on its proprietary MicroPoas® zirconia oxygen sensor technology. The company produces a portfolio of analyzers for combustion control (boilers, incinerators, burners), industrial process monitoring (chemical, steel, pharmaceutical, food and beverage applications), and research laboratories. All products are 100% designed and produced in France, with sensors offered as standalone components, integrated analyzer assemblies, and combined system packages.

Product overview

Setnag is a French company (ISO 9001 certified since 2000) that designs and manufactures oxygen analyzers for controlling gases in combustion, process applications, and fundamental research. The product portfolio is built around the proprietary MicroPoas® technology—a miniaturized zirconia oxygen sensor with built-in metal reference that eliminates the need for reference gas. The core MicroPoas® sensor (3mm diameter, 10mm length) serves as the foundation for multiple analyzer products. The product lineup includes: combustion gas analyzers (ATK/F-EUT, OXYBOX'ATK, ATS/D EUT) for high-temperature applications up to 1300°C; process analyzers (TTH, JC range, S24N-EUT, LISO/P, LISO/F, OXYBOX'AIR + S24N-EUT); oxygen pump gauges (GEN'AIR with automation system); and partial pressure measurement instruments (JOK'AIR, OXYBOX'ATM). Applications span power and energy production, industrial processes, research, control laboratories, safety, heat treatment, food-processing, pure gas production, and waste incineration.

Direct peers

• Servomex: UK-based global specialist in gas analyzers (oxygen, combustion, emissions) for industrial and process applications. Closest direct peer: Servomex sells paramagnetic and zirconia O2 analyzers into the same combustion, incineration, and process markets as Setnag, and is the most commonly cited alternative for MicroPoas®-based systems.
• Endress+Hauser: German-headquartered global leader in industrial process instrumentation, including combustion and flue-gas O2 analyzers (e.g., Oxymax). Direct competitor in the same procurement contexts as Setnag, with a much broader portfolio and global service network.
• AMETEK Process & Analytical Instruments: US-based manufacturer of process oxygen and combustion analyzers (e.g., Thermox). Sells into the same power, incineration, and chemical process segments as Setnag via a global direct/channel model.
• Yokogawa Electric: Japanese process automation major with zirconia and paramagnetic O2 analyzers for combustion and process control. Competes with Setnag in industrial process and power generation applications globally.
• HORIBA: Japanese-headquartered manufacturer of gas analyzers (zirconia, paramagnetic, electrochemical) for combustion, emissions, and process applications. Closely comparable in product category, particularly in European and Asian industrial markets.
