EVERYTHING YOU NEED TO KNOW ABOUT PROCESS REFRACTOMETERS

Vaisala’s Pioneering Liquid Measurement Solution

Filterfine Vietnam – the official distributor of Vaisala process refractometers in Vietnam – proudly introduces Vaisala’s next-generation process refractometer solutions. These instruments deliver accurate, stable, and robust liquid concentration measurements, helping manufacturers optimize production processes and ensure consistent product quality across modern industries.

What Is a Process Refractometer?

A process refractometer is an instrument designed to measure the concentration or composition of liquids directly in-line within pipelines or tanks, based on the Refractive Index (RI) principle.

Unlike traditional sampling-based measurement methods, process refractometers enable:

• Inline, continuous, real-time measurement

• No need for manual sampling or laboratory analysis

• Accurate control of concentration, density, or dissolved solids

Process refractometers are essential measurement tools in industrial automation and process control systems.

Polaris™ Process Refractometer – Vaisala’s Leading-Edge Technology Platform

Vaisala has developed the Polaris™ Process Refractometer family—an entirely new generation of optical inline refractometers engineered to meet the most demanding industrial measurement requirements.

The Polaris™ series enables manufacturers to:

✅ Measure liquid concentration inline and in real time
✅ Achieve stable and precise process control
✅ Reduce raw material consumption, energy usage, and process time
✅ Ensure long-term reliability in harsh operating conditions
✅ Seamlessly integrate with automation systems

Three Key Advantages of Vaisala Polaris™ Process Refractometers

🌟 1. High Accuracy and Long-Term Stability

Polaris™ process refractometers use digital optical refractive index measurement technology, delivering:

✔ High measurement accuracy with no signal drift over time
✔ Insensitivity to color, bubbles, or suspended particles
✔ Automatic temperature compensation for stable results under all operating conditions

📊 2. Inline, Real-Time Measurement Ready for Automation

The refractometer is installed directly on:

• Pipelines

• Tanks

• Reactors

It enables:

▶ Continuous data transmission to PLC / DCS systems
▶ Immediate process monitoring and control
▶ Full compatibility with automated and semi-automated production lines

🧪 3. Robust Performance in Harsh Industrial Environments

Vaisala Polaris™ process refractometers are designed to:

🔹 Withstand high temperatures and pressures
🔹 Operate reliably with corrosive chemicals
🔹 Meet industrial hygiene and sanitary requirements
🔹 Offer options for hazardous areas (ATEX / IECEx certified)
