Instrument Introduction

pHThe electrode measurement method is the glass electrode method.pHThe value is obtained by measuring the electromotive force of the battery, and this principle and method are consistent with the national standard methodGB 6920-86Consistency is a relatively mature detection method that can ensurepHStable and reliable long-term measurement. The single pore structure allows direct contact between the reference liquid and the measuring medium, ensuring high reproducibility, stability, and reaction rate in long-term measurements.

The conductivity detection adopts the quadrupole electrode method. In accordance with industry standardsHJ/T 97-2003The technical requirements for conductivity water quality automatic analyzer require consistency in principle. Good stability, suitable for long-term automatic operation of online monitoring systems.

Dissolved oxygen electrode is detected by fluorescence method. Fluorescence method is based on the principle of quenching effect of oxygen molecules on fluorescent substances, and determines the content of fluorescent substances in the sample solution based on the intensity of fluorescence that occurs in the sample solution. Fluorescence is not affectedCO2andH2SDue to the influence of acidic gases, this electrode can be applied in harsh environments such as acidic gases.

Turbidity adopts90° Light scattering method. The light emitted by the turbidity light source (measuring light) will reflect off the surface of suspended particles in the measuring water, and is set at a distance from the light source90The optical detector at the ° angle can detect reflected light (scattered light). Measure turbidity based on the intensity of scattered light detected and the concentration of suspended solids in water. The automatic intelligent cleaning device ensures long-term stable operation.
