1、 Instrument Introduction
Shanghai Xuantian SJT-6000A typeOnline alkali concentration meterIt is a type of electrode measurement principle that collects the physical and chemical properties of a solution (such as conductivity, refractive index, density, etc.) through dedicated sensors. After signal processing and data conversion, it directly outputs concentration values, providing key data support for production process control, quality assurance, and safety protection. It is widely used in chemical, metallurgical, water treatment, papermaking and other process links involving the preparation, use or recovery of liquid alkali.
2、 Main features
1. Real time online monitoring
Measuring within 3 seconds, real-time reflection of changes in liquid alkali concentration, avoiding the lag of offline sampling analysis, and facilitating timely adjustment of processes (such as controlling the amount of liquid alkali added in acid-base neutralization reactions).
2. Adapt to industrial working conditions
The electrode material and equipment structure (waterproof, corrosion-resistant shell) are resistant to high concentrations of liquid alkali, high temperatures (such as 0-90 ℃), and certain impurities (such as a small amount of suspended particles), making them suitable for harsh environments in industrial sites.
3. Automation and Intelligence
Online alkali concentration meterEquipped with automatic temperature compensation function (to solve the impact of temperature on conductivity), data can be directly connected to the production control system to achieve closed-loop control (such as automatic adjustment of liquid alkali injection amount).
4. Easy to operate and low maintenance
No need for complex reagents (only standard solution for calibration), avoiding the problems of reagent consumption and waste liquid treatment in chemical methods (such as titration); Daily maintenance mainly involves regular cleaning of electrodes (to prevent scaling from affecting measurements), with low maintenance costs.
3、 Typical applications
Chlor alkali industry: Monitor the concentration of sodium hydroxide produced by electrolysis to ensure product purity.
Accident chlorine absorption system: monitoring the concentration of the absorption tower inlet/circulating alkali solution to ensure a safe range of concentration between 15% and 20%.
Fine chemical industry: precise control of alkaline concentration during neutralization reactions and catalyst preparation processes.
