Enough about you. Let’s talk about us.

Unisense Environment is the leading supplier of nitrous oxide (N2O) emissions measurement for wastewater treatment plants and has experienced significant growth in recent years. We manufacture a sensor system for measuring nitrous oxide emissions and optimizing the treatment process at WWTPs. Nitrous oxide (N2O) is a byproduct of the biological treatment process, and with a global warming potential of 273 times that of carbon dioxide (CO2), it is a substantial part of the total climate impact of wastewater treatment.

Unisense Environment (www.unisense-environment.com) was founded in 2013 with the goal of developing and providing sensor technology for industrial applications. In 2014, we launched the world’s first industrial nitrous oxide sensor, which enabled wastewater treatment plants to monitor and control their nitrous oxide emissions. With the growing focus on and demand for climate-neutral wastewater treatment, the company is experiencing significant growth and demand for its products and expertise.

Unisense Environment is a subsidiary of Unisense (www.unisense.com). Since its founding in 1998, Unisense has developed and sold measurement systems for research purposes. Today, the company has 33 employees and is experiencing solid growth and profitability. We are the market leader in electrochemical microsensors for measuring dissolved gases, such as hydrogen sulfide, oxygen, hydrogen, and nitrous oxide. We export 95% of our products.
