We are a Portuguese deep-tech company turning more than 25 years of electrochemical sensor research into a simple field tool for the people who manage water.
Nitrogen Sensing Solutions (NS2) is the company behind Specio. Founded in 2019, it draws on more than 25 years of electrochemical sensor research to make lab-grade nitrogen measurement possible on site, where the water is.
The sensing technology inside every Specio test was developed and refined by the NS2 team — an electrochemical platform built for fresh and salt water and validated against certified laboratory methods.
Specio AnalyticsSpecio Analytics is our North American business, launching officially in January 2027. It brings the Specio platform to customers across the United States and Canada.
Through our North American operation, customers get the same lab-grade nitrite answers on site — with local support for pilots, partnerships and everyday use.
Fish farmers, lake managers and treatment plant operators have measured nitrogen in the field for decades. Many good companies sell tools to do it. So why Specio, and why now?
Affordable, but results depend on the eye of the person reading them.
Fast, but they foul, drift and need frequent calibration.
Continuous, but costly, and they report nitrate and nitrite together.
The gold standard, but results take days.
Enzyme sensors have always been highly specific, but too fragile and too sensitive to oxygen to leave the lab. Specio's patent-pending oxygen-scavenger approach and stabilized enzymes deliver nitrite-specific readings in real water: salty, murky or fresh.
Mass-produced printed electrodes, miniature electronics and the smartphone have shrunk the analyzer to the size of your hand. It is the glucose-meter model, applied to water.
The result: a specific nitrogen answer, on site, in minutes, at a cost that makes frequent testing practical.
See how it worksEvery water decision made with clear nitrogen data.
Give the people who manage water fast, specific nitrogen measurements on site, so they can act before problems become crises.
