Online liquid alkali concentration analyzer

Instrument Introduction

Shanghai Xuantian SJT-6000A typeOnline liquid alkali concentration analyzerIt is an intelligent water quality analysis instrument based on electrochemical principles, which can measure the concentration of sodium hydroxide (NAOH) 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 protection water treatment.

Technical Features

Integrated temperature measurement electrode, single electrode can complete measurement;

Online liquid alkali concentration analyzerBuilt 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.

Typical application scenarios

1. Chlor alkali industry

Monitoring the concentration of alkaline solution at the outlet of the electrolytic cell (controlled at 32%~35%) to ensure stable product quality;

Concentration monitoring in the evaporation section to prevent pipeline scaling caused by excessive concentration.

2. Chemical production

Control the reaction process in industries such as soda ash and pharmaceuticals, dynamically adjust the feeding amount, and reduce drug consumption by 20%;

Automatic settlement of liquid alkali material unloading, with an accuracy of 0.1%, refreshing data every 5 seconds.

3. Environmentally friendly water treatment

Wastewater pH adjustment system, precise addition of liquid alkali to avoid chemical waste;

Wastewater treatment in the electroplating and electronics industries to ensure efficient removal of heavy metals.

4. Paper making and textile

Control the concentration of papermaking cooking solution to improve fiber separation efficiency;

Pre treatment of textile printing and dyeing to ensure uniform concentration of alkali solution and improve dyeing quality.
