Alkali concentration online detector

Instrument Introduction

Shanghai Xuantian SJT-6000A typeAlkali concentration online detectorIt is an intelligent water quality analysis instrument based on the principle of conductivity method, which can measure the concentration of NaOH liquid alkali in solution in real time and continuously. It is designed for industrial environments and widely used in fields such as chemical, petroleum, power, steel, papermaking, textile, new energy, and environmental water treatment.

working principle

The core components are the display and electrodes, which achieve accurate measurement by detecting the linear relationship between the conductivity and concentration of the solution. The built-in temperature sensor automatically compensates for the influence of ambient temperature on the results, and transmits them to the display through a high impedance circuit. After amplification and conversion, the corresponding concentration value is output.

Technical Features

Integrated temperature measurement electrode,Alkali concentration online detectorMeasurement can be completed with a single electrode;

Built in automatic temperature compensation, real-time correction of measured values, eliminating temperature deviation;

Low cost, fast response time (T90<60 seconds), no need for sample pretreatment, suitable for continuous online monitoring;

Two sets of relay outputs, capable of independently and freely selecting high and low position control;

It has a current output of 4-20mA, and the communication interface can be selected as RS-485, making it easy to connect to PLC/DCS control systems;

The program design is simple and the user interface is clear, ensuring that users can directly get started with the operation.
