Product Description

NMD-99 intelligent acid alkali salt concentration analyzer is a new continuous online monitoring instrument designed according to the principle of electromagnetic induction method. The sensor does not contact with the medium, so there is no polarization effect. It has the incomparable advantages compared with the general sensor in the continuous online concentration and conductivity measurement of acid, alkali, salt, corrosive medium etc.
