CHNSpec CRN Series Inline Refractometer: Empowering Precise Industrial Concentration Control

In industrial production fields such as food and beverage, textile dyeing, and chemical manufacturing, real-time and precise monitoring of liquid concentration is a core link for ensuring product quality, optimizing production processes, and reducing operating costs. Traditional offline sampling detection has pain points such as data lag, large manual error, high consumable cost, and easy disruption of production continuity. In contrast, Inline Refractometers (online liquid concentration measuring instruments), with their real-time, continuous, and intelligent monitoring characteristics, have become core equipment for concentration control in modern industrial production. Among them, CHNSpec, deeply engaged in industrial optical detection for many years, has launched the CRN50/52/56 series Inline Refractometers, which—through the core advantages of precision, stability, and strong adaptability—provide reliable concentration monitoring solutions for various industries.

The core value of the CHNSpec CRN50 series Inline Refractometer is first reflected in the accuracy and stability of data detection. Supported by advanced optical detection technology, this series can effectively avoid interference from bubbles, color, turbidity, and other factors in the medium, and is not affected by pressure or flow fluctuations during production. It can steadily output key data such as refractive index, temperature, and concentration. Its measurement accuracy can reach ±0.1%, refractive index resolution reaches 0.0001, and temperature control accuracy is 0.5°C, enabling it to capture subtle concentration variations and provide precise data support for process adjustment. In addition, the device is equipped with a multi-point temperature compensation system and concentration curve correction function to adapt to detection requirements under different temperature conditions. No additional reagents or consumables are needed, which not only reduces usage costs but also avoids secondary contamination, ensuring data accuracy throughout the entire production cycle at the technical level.

Flexible adaptability and convenient operation allow the CHNSpec CRN50 series Inline Refractometer to integrate seamlessly into various complex industrial scenarios. To meet installation requirements in different production processes, this series supports multiple installation methods such as pipeline and tank mounting. With customized accessories such as small-diameter adapters, tee pipes, and sanitary adapters, it can be rapidly deployed, significantly reducing installation time and retrofit costs. The probe is rigorously calibrated before leaving the factory and can be used immediately after delivery. It also supports on-site RI calibration and adjustment, allowing users to build their own data models according to the characteristics of the production medium and customize parameters to further enhance testing accuracy. The device is equipped with a 1.4-inch built-in display and supports multiple signal output methods such as 4–20mA and RS485. This not only enables real-time data visualization but also supports remote transmission, allowing managers to monitor production status at any time without the need to remain on site in harsh working conditions.

The deep integration of intelligence and durability is another major advantage of the CHNSpec CRN50 series. This series is equipped with high-performance intelligent chips, and the probe light source has a service life of up to 100,000 hours, greatly reducing the replacement frequency of critical components. The liquid-contact part adopts SS316L stainless steel combined with high-strength optical glass, capable of withstanding process temperatures from –20°C to 100°C. With an IP68 protection rating and a pressure tolerance ≤1.5MPa, the device is suitable for humid and corrosive industrial environments. For special needs such as strong acids and alkalis in the chemical industry or sanitary requirements in the food industry, the CRN56 model can be equipped with sapphire lenses, Hastelloy, and other special materials, and supports CIP in-place cleaning and SIP in-place sterilization to meet high-demand production scenarios. Additionally, the device has a built-in probe state self-diagnosis function that can quickly locate faults and shorten downtime, and optional components such as ultrasonic cleaning and high-pressure flushing further reduce maintenance costs.

The differentiated designs of CHNSpec CRN50/52/56 three models provide targeted solutions for diverse industrial working conditions: CRN50, as the basic model, is suitable for concentration monitoring in conventional production scenarios such as food and beverages and daily chemicals, balancing accuracy and cost performance. CRN52 upgrades corrosion-resistant materials and can handle media with moderate corrosiveness, suitable for textile dyeing and electroplating industries. CRN56, as the high-end customized model, with advantages such as sapphire lenses and Hastelloy, becomes the preferred choice for strong acids and alkalis and high-wear working conditions in chemical applications. In practical applications, this series can capture concentration fluctuations in real time during crude syrup monitoring in sugar mills, avoiding raw material waste during crystallization; in the dyeing industry, it can achieve real-time control of dye solution concentration to solve fabric color-difference problems; in the chemical field, the combination of corrosion-resistant materials and precise detection ensures long-term stability of strong acid solution concentration monitoring, helping enterprises achieve refined production.

From technological accumulation to scenario implementation, the CHNSpec CRN50/52/56 series Inline Refractometer is not only an industrial detection device but also a core support for enterprises to achieve intelligent production and cost reduction with efficiency improvement. With precise detection capability, flexible adaptability, and durable product design, it solves many pain points of traditional concentration monitoring and demonstrates high adaptability in applications across food and beverage, textile dyeing, and chemical industries. For enterprises seeking production efficiency and product quality, the CHNSpec Inline Refractometer—relying on its reliable performance and systematic solutions—has become a premium choice for online liquid concentration measurement, helping enterprises steadily advance on the road of refined production.
