What Unisense Environment does
Unisense Environment A/S is a Denmark-based industrial sensor company, founded in 2013 as a subsidiary of Unisense, that develops and markets the N2O Wastewater System, a Clark-type electro-chemical sensor platform for real-time measurement of dissolved nitrous oxide (N2O) directly in the liquid phase of wastewater treatment biological tanks. The system comprises the N2O Wastewater Sensor (digital, currently generation 3.0), Connector Unit, Operator Console, and Controller, with accessories including a Calibration Kit, Weather Protection, and Chain Mount Kit. Emissions are calculated from liquid-phase concentration using a modified Henry's law, validated against off-gas measurements at multiple full-scale WWTPs, and can be transmitted directly to PLC or SCADA systems for automated process control.
The company was the first to launch an industrial N2O wastewater sensor in 2014 and remains the only identified provider of this specific sensor technology, with deployments at 500+ WWTPs across Denmark, the UK, Germany, the Netherlands, Belgium, New Zealand, the USA, and Canada. Customers are municipal and private wastewater utilities and treatment plant operators that need to measure, monitor, and reduce N2O emissions for regulatory compliance (notably Denmark's 2025 N2O limit for plants 30,000+ PE), process optimization, and sustainability reporting. Revenue is generated primarily through hardware sales of the sensor system and consumables (calibration kits, replacement sensor heads), with software and data management via the Operator Console, supported by direct enterprise sales and a distributor network (e.g., IMD in the Netherlands). The company is ISO 9001 certified and is actively expanding internationally through partnerships with consultancies (DHI, Jacobs, NIRAS), utilities (Severn Trent, BIOFOS, Aquafin, Halton Region, NEW Water), and trade associations (US Water Alliance, Danish Trade Council).

Unisense Environment product offering
Product offeringCore offering
Unisense Environment A/S manufactures and sells continuous online N2O (nitrous oxide) wastewater sensors and associated instrumentation for biological wastewater treatment plants. Its core product is a Clark-type electrochemical microsensor system — comprising a sensor head, connector unit, controller, operator console and calibration kit — designed for in-situ monitoring of dissolved N2O in activated sludge to support aeration control, process optimisation and greenhouse-gas reporting at municipal and industrial WWTPs.
Product overview
Unisense Environment offers a unified N2O Wastewater System for continuous, real-time measurement of nitrous oxide emissions at wastewater treatment plants. The product portfolio centers on the N2O Wastewater System (now in its 3.0 generation), which comprises the N2O Wastewater Sensor 3.0 (digital), N2O Wastewater Connector Unit 3.0, and N2O Wastewater Operator Console 3.0 as core components. Supporting products include the previous-generation Sensor 2.0 and Controller 2.0, replacement Sensor Heads using Clark-type electro-chemical technology, Calibration Kit, Weather Protection and Pipe Mount, and Chain Mount Kit. The system measures dissolved N2O directly in the liquid phase, calculates emissions based on air stripping using modified Henry's law, and integrates with SCADA/PLC systems for automated process control. The company launched the world's first industrial N2O Wastewater Sensor in 2014 and continues as the only provider of this specific sensor technology for wastewater treatment applications.

Unisense Environment competitors and assessment
Company assessmentDirect peers
- Mettler-Toledo (Process Analytics): Manufacturer of inline process analytical sensors (pH, dissolved oxygen, conductivity, gas) for industrial water and wastewater applications. Directly comparable in that it sells electrochemical sensor systems integrated with plant control systems.
Broad incumbents
- Veolia Water Technologies (incl. Krüger, Hubgrade): World's largest water services and technology provider; Krüger (a Veolia subsidiary) is both an Unisense partner and a supplier of optimization platforms (Hubgrade) bundling N2O modules. Comparable as a competing/channelling route for WWTP emissions monitoring.
- SUEZ Water Technologies & Solutions: Global water and wastewater solutions provider offering treatment technologies plus digital monitoring platforms. Comparable as a large incumbent that could either partner with or compete against a niche N2O sensor supplier for utility accounts.
- Endress+Hauser: Global process analytical instrumentation leader with strong liquid analysis and gas analyzer portfolios serving water/wastewater, chemicals, and food/beverage plants. Comparable as a supplier of inline electrochemical and optical sensors used for process monitoring in wastewater treatment plants.
- Xylem (including YSI, WTW): Global water technology major with a broad portfolio of smart metering, network management and water-quality monitoring instrumentation. Comparable as a multi-product supplier to wastewater utilities pursuing process optimization and emissions reduction.
- Hach (Danaher): Major water-quality instrumentation manufacturer offering online sensors, probes, and controllers for municipal wastewater plants. Comparable because it provides the SCADA-integrated monitoring hardware (sensors, controllers, software) that utilities pair with N2O measurement.
Emerging players
- Real Tech Inc. Canadian manufacturer of online water quality sensors and controllers for municipal and industrial wastewater treatment plants. Comparable as a smaller player supplying SCADA-integrated monitoring instrumentation to the same WWTP buyer segment.
- s::can (now part of Xylem): Specialist in online UV-Vis spectroscopic water quality sensors for drinking water and wastewater monitoring. Comparable as a niche sensor supplier to WWTPs targeting nutrient, organics, and emerging pollutant monitoring.
Others
- Royal HaskoningDHV: International engineering consultancy co-leading the UK/Ireland Process Emissions Community of Practice with Jacobs and advising utilities on N2O/CH4 monitoring. Comparable as a consulting partner influencing WWTP emissions monitoring procurement decisions.
- DHI A/S: Danish water-environment consultancy and software vendor (DIMS CORE) that co-developed N2O measurement technology with Unisense Environment and VCS Denmark. Comparable as both an enabling technology partner and a potential route for digital monitoring services.
