Fertimeter NPK3

Electronic System for the concentration measurement of the nourishing contents of slurry.

NPK3 is a device able to measure in real time the percentages of total nitrogen, ammonia nitrogen, phosphorus and potassium, in order to spread the slurry according to the detected composition, reducing environmental risks and saving chemical fertilizer.

The control unit measures, through the probe, the temperature and the electroconductivity of the sewage and obtains the concentration of the nutrients through the correlation curves.
Electroconductivity is expressed in mS/cm, concentrations in kg/m3.
