$MS-480 Online Refractive Index & Concentration Analyzer$

Product Overview

Continuous Concentration Measurement Without Sampling Delay The MS-480 continuously measures refractive index at the interface between the sensor and process liquid. Temperature compensation and an application-specific model convert the optical measurement into concentration, °Brix or other validated process values, helping reduce dependence on periodic laboratory sampling. Typical applications include pipelines, mixing systems, evaporation processes, recovery systems and concentration-control points.

Suitable Process Media

Suitable for selected: Sugar, syrup and beverage solutions Acids and chemical solutions Organic solvents and recovery liquids Cutting, grinding and cleaning fluids Antifreeze and other process liquids Final suitability depends on medium composition, concentration range, temperature and process conditions.

Measurement Principle

The sensor uses an LED light source, sapphire optical surface and optical receiver to measure refractive behaviour at the liquid–sensor interface. The analyzer combines the measured refractive index with temperature compensation and an application-specific calibration model to calculate the required concentration or °Brix value.

Key Advantages

1、 Continuous Process Measurement Provides continuous concentration

data directly from the process, enabling faster feedback and reducing dependence on routine manual sampling. 2、High‑Resolution Measurement Provides concentration accuracy up to ±0.05%, concentration resolution of 0.01% and refractive‑index resolution of 0.00001 . 3、Reliable Optical Sensor The LED light source, sapphire optical surface and movement‑free sensor design support stable operation with low routine maintenance.

4、 Flexible Integration Supports 4–20 mA output,

RS485 Modbus communication and multiple corrosion‑resistant sensor materials for industrial process integration.
