Which Brand of Inline Refractometer Is Recommended for Inline Liquid Concentration Monitoring?

In industrial production processes, stable control of liquid concentration is directly related to product quality consistency and production efficiency. Traditional offline testing methods suffer from strong lag and complex operations, making it difficult to meet the real-time monitoring requirements of modern production. The CHNSpec Inline Refractometer CRN50/52/56 series, with its flexible installation design, stable detection performance, and intelligent functional configuration, provides efficient solutions for liquid concentration detection across multiple industries, becoming a reliable support for precise concentration control in industrial production.

Flexible installation and adaptability to diverse scenarios are prominent advantages of this refractometer series. In industrial production environments, complex layouts of pipelines and tanks place high demands on the installation compatibility of detection instruments. CHNSpec Inline Refractometers fully consider actual operating conditions, supporting compact clamp connections and offering multiple flange specifications as optional configurations. Combined with small-diameter installation adapters, tee/four-way pipes (with viewing windows), sanitary adapters, and other customized accessories, they can easily adapt to different production equipment and installation environments. This significantly reduces installation time and labor costs, enabling rapid commissioning without major modifications to existing production processes.

Stable and accurate detection is the core requirement of industrial testing instruments. CHNSpec Inline Refractometers adopt advanced detection technologies that effectively avoid interference caused by medium characteristics and operating condition changes. Even when measuring liquids containing bubbles, dark colors, or high turbidity, they can still output accurate and stable data. This series offers a wide measurement range: CRN50/52 models cover a concentration range of 0.0–90.0%Brix, while the CRN56 model extends to 0.0–100%Brix. The refractive index measurement range reaches up to 1.33299–1.57041, with resolutions of 0.01% concentration, 0.00001 refractive index, and 0.1°C temperature. Measurement accuracy is controlled within ±0.1% concentration, 0.0001 refractive index, and 0.5°C temperature, providing reliable data support for concentration regulation during production.

Convenient operation and intelligent maintenance design further enhance the practical value of the instruments. The probe is strictly calibrated before leaving the factory and features built-in multi-point temperature compensation. Delivered as a complete set, it is ready to use immediately after installation without complicated debugging procedures. It also supports RI calibration and adjustment, allowing users to correct measurement deviations on site according to actual needs. With the built-in concentration data processing system, users can establish their own data models and customize parameters to optimize detection accuracy for different media. In addition, the instrument includes probe status self-diagnosis, enabling rapid fault localization and reducing downtime for maintenance. When combined with the CRN5-C1 ultrasonic cleaning component and CRN5-C2 high-pressure flushing component, efficient cleaning is achieved, ensuring long-term stable operation.

Intelligent and durable product features meet the long-term usage requirements of industrial production. This series of refractometers uses intelligent chips and requires no additional reagents or consumables, reducing operating costs and environmental impact. The probe light source has a lifespan of up to 100,000 hours, with low power consumption and high stability. The wetted parts are made of high-grade materials: CRN50/52 models use SS316L stainless steel combined with high-strength optical glass, while the CRN56 model upgrades to SS316L stainless steel and sapphire. Optional materials such as PTFE and Hastelloy are available according to medium characteristics. The temperature resistance range covers process temperatures of -20 to 70°C (up to 100°C maximum), cleaning temperatures from 0 to 120°C, and compatibility with CIP (Clean-In-Place) and SIP (Sterilize-In-Place) processes. The protection rating reaches IP68, pressure resistance ≤1.5 MPa, and explosion-proof rating Ex ia IIC T6 Ga, enabling adaptation to complex and harsh industrial environments.

Rich functional expansion and wide application scenarios demonstrate strong multi-industry adaptability. The instrument is equipped with a 1.4-inch built-in display and supports multiple signal outputs such as 4–20 mA and RS485. It can be paired with a separated display controller, multi-channel data acquisition control systems (supporting up to 120 channels), and wireless data transmission modules to achieve remote monitoring and centralized management of production processes. In the food and beverage industry, it accurately detects sugar and other component concentrations to ensure consistent taste. In metal processing and manufacturing, it enables real-time monitoring of cutting fluid concentration to extend tool life. In the biopharmaceutical field, sanitary-grade materials and cleaning processes meet stringent production standards. In environmental protection and chemical industries, it can be applied to wastewater treatment and chemical raw material concentration monitoring, supporting green production.

With comprehensive advantages including flexible installation, precise detection, convenient operation, and durable reliability, the CHNSpec Inline Refractometer CRN50/52/56 series builds a one-stop solution for industrial liquid concentration detection. By monitoring concentration changes in real time during production, it helps enterprises promptly adjust process parameters, improving production efficiency while ensuring product quality stability. Its multi-scenario adaptability and intelligent design enable it to play an important role across industries such as food and beverage, biopharmaceuticals, and environmental chemicals, providing strong support for refined and efficient industrial production.
