Inline Refractometer

Inline Refractometers

An inline refractometer is a sensor installed directly in pipelines or tanks to continuously measure the concentration or refractive index of liquids in real time. By detecting how light bends through a solution, it provides instant readings without manual sampling. This allows for automatic process control, improves product consistency, reduces waste, and lowers labor costs—making it a valuable tool in industries such as food, chemicals, pharmaceuticals, and battery production.

Our Inline Refractometer Models

We offer a range of high-precision inline refractometers designed for industrial and laboratory use. Each model features automatic temperature compensation (ATC), a sapphire prism for durability, and both 4–20mA and RS-485 outputs for easy integration with control systems.

 - Sugar & Brix Refractometers

Measure sugar concentration (0–93% Brix) in juices, syrups, and honey for food and beverage production.

 - Ethylene Glycol / Antifreeze Models

Used in automotive and chemical applications to monitor glycol concentration in real time (0–90%).

 - NMP Solvent Refractometers

Designed for lithium battery production, these models ensure accurate concentration control during distillation and recycling.

 - General Industrial Models

For monitoring coolants, cutting fluids, or chemical mixtures in process lines, supporting stable and efficient production.
