Industrial Online Refractometer Fully Automatic Online Concentration Meter Real-Time Measurement Without Sampling - AMT-ZGY-201

I. Industrial Online Refractometer Fully Automatic Online Concentration Meter Real-Time Measurement Without Sampling Product Introduction

Online refractometer, also known asOnline concentration meter, online refractive index concentration analyzer, based on the principle of total reflection critical angle of light in liquid, detects the liquid refractive index in real time, and converts and outputs solution concentration, sugar content, solid content, and medium temperature, achieving real-time detection of liquid in production pipelines and reactors.Uninterrupted in-situ online monitoring。

No manual sampling or reagent consumables required; the probe is directly installed in pipelines, tanks, or bypass loops for 7×24-hour continuous detection, with measurement data uploaded to the central control system in real time. It can be linked with PLC/DCS for closed-loop automatic concentration control, replacing traditional manual titration and handheld refractometer spot checks, eliminating pain points such as sampling lag, large human errors, and unstable batches. Widely used for liquid concentration control in industrial production processes.

The instrument is divided intoProbe + transmitter split type / integrated display typeTwo structures available: standard industrial type and sanitary food-grade, explosion-proof, and anti-corrosion type, suitable for transparent and semi-transparent liquids; slightly turbid media can also be measured stably without interference from liquid color.

II. Industrial Online Refractometer Fully Automatic Online Concentration Meter Real-Time Measurement Without Sampling Measurement Principle

The light source emits light onto the contact surface between the sapphire prism and the measured liquid. When light enters the liquid from the prism, total reflection occurs; the CCD photosensitive array captures the position of the total reflection critical ray, calculates the liquid refractive index, and combined with the built-in temperature compensation algorithm, converts the refractive index into the corresponding solution concentration value, while outputting real-time temperature data.
