Exceptional accuracy throughout the entire process: CRN36 Series Inline Refractometer
In precision industrial production, concentration fluctuations in every drop of raw material can affect the quality of the final product. The CRN30/32/36 Series Inline Refractometers are monitoring tools tailored for your demanding process environments. They are not just sensors but also "digital eyes" conducting 24/7 uninterrupted inspections in your plant. True process control is not just about "seeing" data but "anticipating" trends. With 24-hour continuous monitoring, the CRN Series helps you respond before quality deviates from standards, thereby significantly improving yield rates and reducing raw material waste.
Core values: Real-time, Precision, No Compromise
1. Real-time Concentration Monitoring: Say goodbye to the lag of laboratory sampling. The CRN Series provides continuous measurement with second-level response, ensuring that every step—from raw material receiving and semi-finished processing to final product output—remains under control.
2. Data Accuracy: Delivers real-time concentration measurement results comparable to laboratory benchtop refractometers.
3. Built for Extreme Environments: Adopting a rugged industrial-grade design, it can be installed directly on pipelines or tanks. Even under fluctuating process temperatures, the built-in high-precision temperature compensation system ensures consistent measurement values.
4. Fully Automated Production Control: Sensor data can be seamlessly integrated into your PLC or control system to achieve closed-loop automatic adjustment of the production process, significantly reducing labor intervention costs and error rates.
Technical Highlight
Measurement Principle Adopts the critical angle total reflection principle, unaffected by bubbles, solid particles, or color.
Robustness Sapphire prism and stainless steel housing, resistant to corrosion and high pressure.
Temperature Compensation Monitors process temperature in real time with automatic compensation to reference temperature
Maintenance Cost Modular design with no wearing parts, resulting in extremely low maintenance frequency.
