Devices Laboratory




Nitratomer pNO3-07 is designed to measure the activity of nitrate ions NO3 - (pX mode), the concentration of nitrate ions NO3 - (C x mode), the emf of the electrode system (regime E) and temperatures (t) of the analyzed media.

Nitratomer used for measurements in laboratory practice, as well as for operational measurements in the food industry and other industries.
