In the core stages of industrial production, real-time and accurate monitoring of liquid concentration directly determines product quality stability, production efficiency, and compliance. Traditional offline sampling and testing methods suffer from strong lag, high labor costs, and susceptibility to environmental interference, making them difficult to adapt to the stringent demands of modern continuous production. The Inline Refractometer CRN50/52/56 series launched by CHNSpec, with its core advantages of “flexible installation, precise detection, and intelligent durability,” provides one-stop concentration monitoring solutions for food and beverage, biopharmaceuticals, environmental chemical engineering, metal processing, and many other industries, thoroughly transforming concentration control models in industrial processes.
Core Advantages: Solving Four Major Pain Points of Industrial Monitoring
1. Full-Scenario Adaptation, More Efficient Installation and Maintenance
Industrial production scenarios are complex and diverse, and different operating conditions such as pipelines, tanks, and small-diameter pipes impose varying installation requirements on monitoring equipment. The CRN50/52/56 series Inline Refractometers break through the limitations of traditional equipment installation, supporting compact clamp connections and multiple flange specifications such as DN25–DN80. Combined with customized accessories including small-diameter installation adapters, three-way/four-way pipes (with viewing windows), and sanitary adapters, installation and deployment can be completed quickly without major modifications to production pipelines, significantly reducing construction time and costs. At the same time, the equipment features self-diagnostic maintenance functions that can quickly locate probe faults. Paired with the CRN5-C1 ultrasonic cleaning module and the CRN5-C2 high-pressure flushing module, it supports CIP (Clean-in-Place) and SIP (Sterilization-in-Place), completely eliminating the complexity of manual disassembly and cleaning and greatly shortening downtime for maintenance.
2. Accurate and Stable, Unaffected by Operating Conditions and Media Interference
In industrial production, changes in media such as bubbles, color, and turbidity, as well as fluctuations in pressure, flow, and temperature, often cause data drift in traditional monitoring equipment. The CRN50/52/56 series adopts advanced optical detection technology, combined with built-in multi-point temperature compensation and concentration curve correction functions, to achieve precise measurement of refractive index, temperature, concentration, and Brix—measurement accuracy reaches ±0.1%, refractive index resolution 0.00001, and temperature resolution 0.1°C. Even within a process temperature range of -20 to 70°C (up to 100°C maximum), it can stably output reliable data. For special media, the equipment supports RI calibration and on-site adjustment, allowing users to custom-build data models to further enhance detection specificity and accuracy.
3. Intelligent Upgrade, Empowering Digital Production
Under the trend of Industry 4.0, real-time and visualized management of production data has become key for enterprises to reduce costs and increase efficiency. The CRN50/52/56 series is equipped with an intelligent concentration data processing system and a 1.4-inch display, enabling intuitive presentation of various detection parameters. It supports multiple signal outputs including 4–20 mA, RS485, RS232, and USB, and is compatible with split display controllers and wireless data remote transmission modules, enabling remote monitoring of production processes and real-time data uploading. Its multi-channel data acquisition and control system can support up to 120 channels, meeting the centralized management needs of multiple production lines in large factories and providing complete data support for production scheduling and quality traceability—truly realizing “unattended” intelligent monitoring.
4. Long-Term Durability, Reducing Overall Operating Costs
Adopting a highly reliable design, the probe wetted materials are selected from SS316L plus high-strength optical glass (CRN52/56 optional PTFE, Hastelloy, titanium, and other special materials), with pressure resistance ≤1.5 MPa, IP68 protection for wetted parts, and ExiaIICT6Ga explosion-proof certification, allowing adaptation to harsh industrial environments. At the same time, the equipment requires no reagent consumables, features a light source lifespan of up to 100,000 hours, low power consumption, and cable extension up to 200 meters, significantly reducing consumable replacement, equipment maintenance, and manual inspection costs, enabling enterprises to achieve long-term stable low-cost operation.
Deep Multi-Industry Applications: Precisely Matching Scenario-Based Needs
1. Food and Beverage Industry: Safeguarding the “Golden Concentration” of Taste and Quality
In the production of beverages, jams, candies, and similar products, sucrose concentration (Brix) is a core indicator determining product taste and shelf life. The CRN50/52/56 series can monitor sugar concentration in real time during production, eliminating the influence of ambient temperature on detection results through temperature compensation to ensure consistent taste across batches. The equipment supports sanitary installation and in-place cleaning, complies with clean production standards in the food industry, avoids cross-contamination, and helps enterprises pass quality compliance certifications.
2. Biopharmaceutical Industry: Ensuring Drug Safety and Efficacy
In biopharmaceutical processes, precise control of drug solution concentration and fermentation liquid components directly affects drug efficacy and safety. The CRN52/56 series adopts sapphire optical materials and optional corrosion-resistant materials, accommodating the monitoring needs of various drug solutions and buffer solutions. Its high-precision measurement capability meets the stringent requirements of GMP certification for process parameter control. At the same time, the equipment supports SIP sterilization-in-place, avoiding secondary contamination during cleaning and providing reliable assurance for “aseptic production” in biopharmaceuticals.
3. Environmental Chemical Industry: Achieving Green and Compliant Production
In processes such as chemical wastewater treatment and acid–alkali solution preparation, concentration monitoring is key to achieving compliant discharge and process optimization. The CRN50/52/56 series is not affected by wastewater turbidity, color, or bubbles and can stably monitor key parameters such as COD and acid–alkali concentration. Data can be uploaded in real time to environmental monitoring platforms, helping enterprises precisely control treatment processes and ensure compliant wastewater discharge. The explosion-proof and corrosion-resistant design allows adaptation to high-risk environments in chemical workshops, ensuring production safety.
4. Metal Processing and Manufacturing: Optimizing Cutting Fluid Performance and Service Life
In metal processing, cutting fluid concentration directly affects machining accuracy and tool life. The CRN series Inline Refractometers can monitor cutting fluid concentration changes in real time, promptly alerting operators to replenish concentrate or add water for dilution, avoiding tool wear and workpiece residue caused by excessive concentration, or equipment corrosion and reduced machining efficiency caused by insufficient concentration. This provides strong support for the stability and economic efficiency of metal processing processes.
Conclusion: Empowering High-Quality Industrial Development with Precise Monitoring
With core competitiveness in “flexible installation, precise detection, intelligent durability, and scenario adaptability,” the CHNSpec Inline Refractometer CRN50/52/56 series breaks through the technical bottlenecks of traditional concentration monitoring and provides full-process solutions from on-site detection to remote control for multiple industries.
