iPR B⁴

Inline Brix Refractometer

The Basic Inline Process Refractometer (iPR B⁴) is a powerful refractometer for continuous quality monitoring in the sugar, pharmaceutical and chemical industries. It enables precise determination of the refractive index (RI) in real time — directly in the product stream — ensuring stable processes, consistent product quality and higher efficiency.

The sophisticated design features a blue anodised air cooling jacket that protects electronic components from overheating at high process temperatures. Equipped with a light source at 589nm, the iPR B⁴ delivers highly accurate RI values directly during the process, without any time loss due to manual sampling.

Key Features

• Attractive entry-level device — ideal price-performance ratio for precise inline analysis.
• Wide measuring and temperature range.
• Real-time control directly in the process.
• Simple, flexible process integration.
• Durable, low-maintenance design.
• CIP/SIP cleaning at prescribed temperatures without removing the appliance.
• UniConfig software included for configuration and data acquisition.
• Two 4-20mA analog outputs and two digital switching outputs for flexible control integration.
• Optional cleaning nozzle or ultrasonic cleaning device.

Applications

Ideal for continuous monitoring of refractive index, interpreted as a customer-specific value such as sucrose concentration (Brix), in sugar factories and sugar-processing industries as well as agriculture. Used in production of cane and beet sugar, molasses, syrup, jam, confectionery, lemonade and fruit juice for liquid identification and interface detection. Also suitable for peptide synthesis and precision concentration control in mechanical and automotive manufacturing.
