Inline Refractometer POLARIS

Inline Brix or concentration measurement 

Concentration measurements are essential for monitoring your process. By measuring these inline in the pipe or directly in a tank, you save time and increase production. 

Accurate concentration measurement that requires no calibration and is unaffected by gas bubbles, particles, colour, pressure and temperature changes offers numerous advantages. With a range of 0 - 100% and a mean accuracy of ± 0.1% you have, above all, certainty when measuring the concentration. 

Each industry (F&B, Chemicals, Pharmaceuticals, etc.) has its own requirements when it comes to process connections, certifications and degree of finish. That's why we consider it necessary to have the right type of refractometer for each industry and application. Customised to your process and application. 

POLARIS - A complete package for inline refractometry 

The Polaris platform is the top solution for industrial refractometry. Polaris refractometers have industry-specific process connections such as tri-clamp or flange connections. 

Moreover, Polaris is a complete package! The sensor can be used as a stand-alone analyser and provides 4-20mA direct output or communicates digitally. Combined with the Vaisala Indigo 520 user interface and InSight software, you can access all the analyser's information, such as calibration history, quality factor, graphical display and diagnostics. You can calibrate, start automatic cleaning and even programme different recipes with separate settings for alternating processes or products.

Also available for use in ATEX zones

The Vaisala Polaris process refractometer is also available in an ATEX-certified version for use in hazardous environments. Depending on the selected configuration, the instrument can be safely installed in Zone 0/1 or Zone 2, ensuring reliable measurements even in the most demanding conditions.

The ATEX versions are fully compatible with the Indigo520 transmitter, which is installed in a safe area. Combined with intrinsically safe equipment for Zone 0 applications, this enables a safe installation without compromising measurement performance.

This allows you to combine maximum process control with safe operation in environments where reliability is critical.
