Contact Us Vaisala K-PATENTS® Sanitary Probe Refractometer PR-43-AP for in-line Brix and concentration measurement The unique and innovative Vaisala K-PATENTS® Sanitary probe refractometer PR-43-AP system consists of a probe refractometer and a graphical user interface. The refractometer is a stand-alone device capable of operating independently. It has a measurement range of 0 to 100 Brix and provides an Ethernet or 4–20 mA output signal proportional to the temperature compensated Brix value for real-time process control. Different user interface options range from a rugged, multichannel, industrial computer to a compact lightweight and a web-based version, and allow the user to select the most preferred way to access and use the refractometer measurement and diagnostics data. The PR-43-AP refractometer is designed to meet the needs of hygienic installations in large pipes, tanks, cookers, crystallizers and kettles and in higher temperatures up to 150°C (300°F). The PR-43-AP refractometer is installed in the pipe line or vessel through a 2.5 inch or 4 inch sanitary clamp. The user interface of the refractometer can be installed locally in the field, remotely in the control room or in both locations by connecting several user interfaces in a network. Features Universal calibration of each sensor: all sensors are freely interchangeable. Full measurement range Refractive Index (nD) 1.3200 – 1.5300, which corresponds to 0-100 Brix. Sanitary 3-A approved and EHEDG certified to meet the highest hygiene requirements of food production. Withstands CIP and SIP processes and cleaning and rinsing of facilities. Completely digital system: particles and bubbles do not affect operation or accuracy. Patented CORE-optics: no drift, no re-calibration, no mechanical adjustments. PR-43-A Refractometer has a built-in web server with an instrument homepage. The homepage allows for configuring, monitoring, verifying and diagnosing the refractometer via an Ethernet connection. Effective heat transfer and isolation using Teflon® and ceramics in the refractometer provide safe operation also in higher process temperatures (max. 150 °C/300 °F). Fast process temperature measurement by built-in Pt1000 and automatic temperature compensation. Easy on-site instrument verification within user’s own quality assurance system and standard Refractive Index liquids. + Show more Key Benefits Hygienic certification The 3-A symbol guarantees that the Sanitary Refractometer PR-43-A conforms to 3-A sanitary standard number 46-04 for refractometers and energy absorbing optical sensors for milk and milk products and it has passed through the independent third party verification inspection for 3-A symbol authorization. Accurate and stable measurement over the full range The measurement is accurate across the full concentration range of 0-100 Brix: R.I. nD ±0.0002 corresponds typically to ±0.1 Brix or % by weight. The measurement is not affected by bubbles, particles, color or vibration. The system withstands CIP and SIP cleaning. Easy maintenance No drift. No re-calibration. No mechanical adjustments.
