Our partners in Netherland PalmSens BV are using one of our custom-made sensors together with one of their potentiostats to measure nitrate directly in one of the local rivers. See the video below, which has been shown on the Dutch Television Show "Nederland Maakt Het" on RTL Z. If you are interested in nitrate measurement, you can contact us here or through our website and hear more about possibilities. The video below is in English.
