    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. 

    The PR-43 Process refractometer is the latest model on the market. It connects reliable measurement technology with the digital industry we find ourselves in today and continuously tries to innovate itself in terms of communication protocols. 

    This model can be used as a stand-alone, which means that it has a built-in web server with homepage as standard. It allows you to monitor, configure and diagnose remotely. In addition to digital communication, each PR-43 model has a 4 - 20 mA output signal.

    • Full measuring range in refractive index (nD) 1.3200 - 1.5300, corresponding to 0-100%.
    • Optional ranges: nD = 1.260 to 1.470;nD = 1.410 to 1.620;nD = 1.520 to 1.730.
    • Fully digital system: particles and gas bubbles do not affect operation or accuracy.
    • CORE optics: no drift, no recalibration, no mechanical adjustments.
    • Special wetted parts alloys like AISI 316L stainless steel, Alloy 20, Hastelloy C276/ASTM C276, Nickel 200/201, Titanium GR2/ATM B348 GR2 are available.
    • Ethernet connection and external data logging capabilities.
    • Process temperature for compact model: -40°C to 130°C, for probe model: -40°C to 150°C.
    • Fast temperature measurement through built-in Pt1000 and automatic temperature compensation.
    • Easy instrument verification with certified standards.
    • Resistant to CIP and SIP cleaning.
    • Certification for Ex n and Ex ia model available.
    • Protection class IP67.
