Nitrate logger sensor NUL-241

Nitrate logger sensor NUL-241

The NeuLog nitrate sensor can be used to measure the concentration of nitrate ions (NO3) in aqueous samples. Nitrates are used in fertilizers and can contaminate water. Also, untreated human sewage can be a source of nitrate contamination. Nitrate measurements can also be very relevant to study the nitrogen cycle in general and to relate this cycle to plants and algae.
