Product Description
The NMD-99 Intelligent Acid, Base & Salt Concentration Analyzer is a new type of continuous online monitoring instrument designed based on the principle of electromagnetic induction. As its sensor operates without contact with the medium, it is free from polarization effects. Compared to ordinary sensors, it offers unparalleled advantages in the continuous online measurement of concentration and conductivity for acids, bases, salts, corrosive media, and more.
