WaterSNIP webinar:
measuring nitrate with sensors
On Monday 8 June, Observator participated as a speaker in the WaterSNIP webinar of the RIVM. WaterSNIP stands for Water Sensors Nutrients Innovation Program. Measuring nitrate with the help of sensors was also the subject of this webinar. Rob Beun, Observator's hydro specialist, spoke about the auto-analyser technique and the associated capabilities of the Systea WIZ probe.
