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.
