What Eco Physics does

Eco Physics AG is a privately held Swiss analytical instrument manufacturer founded in 1989 and headquartered in Dürnten, Switzerland (with a wholly-owned German subsidiary, ECO PHYSICS GmbH). The company designs and builds chemiluminescence detection (CLD) instruments for the measurement of nitrogen oxides (NO, NO2, NOx, NH3) and ozone (O3), claiming the broadest commercially available sensitivity range — from 1% concentration down to 1 part per trillion. Its nCLD platform is organized in four tiers — Economical, Modular, Supreme and Ambient — alongside specialized instruments including the nCLD 88 O3 ozone analyzer, CLD 780 TR, CraNOx II for atmospheric research, M17 for semiconductor CMP process control, and NO-in-Liquids instruments for medical and biochemical research. Manufacturing, R&D and customer support are co-located at the Swiss headquarters.

The company operates exclusively through a global distributor network covering Africa, Asia & Middle East, Australia, Europe, Germany, North America, and Central & South America, with regional partners providing local-language sales, technical support and service. Eco Physics sells into five horizontal use-case segments: environmental/ambient air monitoring and atmospheric research, industrial emission monitoring, automotive/aviation/marine/combustive engine exhaust testing, semiconductor CMP process control, and medical/pulmonary diagnostics (distributed via partner ECO MEDICS AG). Pricing is non-public and quoted through distributors. Notable reference customers include the Izaña Atmospheric Observatory (Tenerife), Fraunhofer-Institut, and the Södra länken Tunnel System in Stockholm. QAL 1 certification by TÜV Rheinland Energy GmbH (July 2021) for the nCLD AL2 and nCLD 855Y, against EN 14211:2012 and VDI standards, anchors the company's access to European regulated ambient air monitoring.

Core offering

ECO PHYSICS AG manufactures and sells tailor-made analytical instruments for the measurement of nitrogen oxides (NO, NO2, NOx, NH3) and ozone (O3), built around proprietary chemiluminescence detection (CLD) technology. Its nCLD product platform spans Economical, Modular, Supreme and Ambient instrument lines, serving environmental monitoring, industrial emission control, automotive/marine exhaust measurement, semiconductor process control, and medical research applications with detection sensitivity from 1% down to 1 ppt.

Product overview

ECO PHYSICS is a Swiss manufacturer of tailor-made analytical instruments for nitrogen oxide (NOx) and ozone measurement. The product portfolio consists of multiple nCLD (nitrogen chemiluminescence detector) product lines arranged by capability level: the Economical Line (cost-effective simplified analyzers), Modular Line (GUI-based with multiple connectivity options), Supreme Line (automatic operation), and Ambient Line (ultra-sensitive environmental monitoring). Core products include the nCLD 88 O3 for ozone detection, CLD 780 TR for high-performance NOx analysis, specialized M17 for semiconductor applications, and NO in Liquids instruments for medical research. All instruments utilize chemiluminescence detection technology enabling unmatched sensitivity from 1% down to 1 ppt detection range.

• Endress+Hauser: Global process instrumentation leader offering gas analyzers and CEMS-relevant devices sold directly to industrial accounts; an indirect competitor where NOx monitoring is part of broader plant packages.
• Servomex: Specialist in gas analysis for industrial process and emissions monitoring; competes with Eco Physics in industrial stacks, combustion, and laboratory-grade NOx measurement.
• Emerson (Rosemount / Xstream): Provides continuous gas analyzers for emissions and process monitoring through Xstream and Rosemount lines; competes in the same industrial and environmental compliance space as Eco Physics.
• HORIBA: Diversified measurement company whose automotive test systems and emissions analyzers compete in the same NOx/vehicle-emissions buying centers as Eco Physics, particularly for engine and catalyst R&D labs.
• SICK AG: German sensor and gas analyzer manufacturer (SICK Maihak) with a strong direct industrial-sales motion; overlaps with Eco Physics on stack emissions, tunnel air quality, and process gas monitoring.
• Teledyne Technologies (Teledyne API): Teledyne API designs NOx and ambient air analyzers using chemiluminescence, directly addressing the same environmental and regulatory monitoring customers as Eco Physics, including QAL-relevant programs.

Emerging players

• MKS Instruments: Provides gas analysis and monitoring solutions for semiconductor and industrial process control; overlaps with Eco Physics in semiconductor CMP-related NOx detection and specialty gas monitoring.
• ECO MEDICS AG: Partner company that distributes Eco Physics-derived pulmonary diagnostic products from neonatology to adult lung function testing; relevant because it anchors the medical/clinical extension of Eco Physics technology.
