Overview

The conductivity method alkali concentration meter is equipped with a PT1000 high-precision temperature sensor, which can collect solution temperature in real time, ensuring measurement accuracy within the range of 0-100 ℃. It supports four installation methods: immersion, pipeline, flange, and flow. The data can be remotely transmitted to the central control room through 4-20mA and RS485 communication.

Product Details

Instrument Introduction

Shanghai Xuantian SJT-6000A typeConductivity method alkali concentration meterIt is a commonly used online alkaline concentration analysis equipment in industrial scenarios, which measures the conductivity and concentration of strong electrolyte solutions (such as NaOH, KOH) based on their quantitative correlation characteristics. It has significant advantages such as simple structure, rapid response, and low maintenance cost, and is widely used in industries such as chemical, chlor alkali, papermaking, and textile.

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.
