Recommended Manufacturers of Inline Refractometers / Inline Concentration Meters

I. A High-Quality Choice Under the Demand for Industrial Monitoring Upgrades

In modern production across the food and beverage, chemical, pharmaceutical, and other industries, real-time and accurate monitoring of liquid concentration is a core link in ensuring product quality and improving production efficiency. Traditional manual sampling detection suffers from data lag, contamination risks, and large errors, making it increasingly unable to meet the quality control needs of continuous production. CHNSpec has deeply cultivated the field of industrial detection for many years, and based on accumulated optical detection and intelligent control technology, launched the CRN50/52/56 series Inline Refractometers / Inline Concentration Meters. With full-scene adaptability and reliable performance, they have become powerful partners for enterprises undergoing intelligent transformation.

II. Core Technical Advantages: Triple Assurance of Accuracy, Intelligence, and Durability

1. High-precision detection with reliable and stable data

The CHNSpec inline measurement instrument uses the refractive index method as the core principle and is equipped with advanced optical detection modules and intelligent signal processing chips, enabling it to effectively avoid interference factors such as bubbles, color, and turbidity in the medium, while remaining unaffected by pressure or flow fluctuations. Its concentration measurement accuracy reaches ±0.1%, refractive index resolution reaches 0.0001, and temperature control accuracy is 0.5°C, allowing it to precisely capture subtle concentration changes. The built-in multi-point temperature compensation system and concentration curve correction function further ensure data accuracy under different working conditions. Without requiring additional reagent consumables, it not only reduces the cost of use but also avoids secondary contamination.

2. Flexible adaptation with convenient installation and operation

The product supports multiple installation methods such as pipelines and tanks, offering compact clamp connections, DN25/DN50 flange specifications, small-diameter adapters, sanitary adapters, and other customized accessories, enabling quick integration into different production processes. The standard cable length is 2 meters and can be extended to 200 meters to meet long-distance installation needs. The probe undergoes strict calibration before leaving the factory, making it ready for installation and use upon delivery, and supports on-site RI calibration and custom data models. The 1.4-inch display screen intuitively shows parameters, and combined with 4-20 mA / RS485 and other output signals, it provides real-time visualization and remote transmission of data, allowing managers to monitor production status conveniently.

3. Durable and robust, suitable for complex working conditions

The wetted parts are made of SS316L stainless steel paired with high-strength optical glass. The CRN52/56 models offer optional sapphire, Hastelloy, and other special materials, withstanding process temperatures of -20°C to 70°C and cleaning temperatures up to 120°C. With an IP68 protection rating, a pressure resistance of ≤1.5 MPa, and an explosion-proof rating of Ex ia IIC T6 Ga, the devices can adapt to harsh industrial environments involving high temperatures, high pressures, and corrosive conditions. They support CIP in-place cleaning and SIP in-place sterilization, meeting the hygienic production requirements of the food and pharmaceutical industries. The probe light source has a long lifespan of up to 100,000 hours, and the built-in self-diagnosis function can quickly locate fault points, reducing downtime and maintenance duration.

III. Main Model Analysis: Adaptation to Diverse Scenarios

1. CRN50 Series: High-Cost-Performance Basic Model

As the entry-level model of the series, the CRN50 meets the needs of standard industrial scenarios with stable performance. The wetted material adopts SS316L stainless steel and high-strength optical glass, with a measurement range covering 0.0–90% Brix, refractive index range of 1.33299–1.51782, and a resolution of 0.01%. It is suitable for syrup and juice concentration monitoring in the food and beverage industry, as well as general cutting fluid concentration control in metal processing. With easy installation and low maintenance cost, it is an economical choice for small and medium-sized enterprises upgrading quality control.

2. CRN52 Series: Enhanced Corrosion-Resistant Model

The CRN52 upgrades the wetted materials based on the CRN50, featuring SS316L stainless steel and a sapphire window with significantly improved corrosion and wear resistance. It supports customized non-standard scales and can build dedicated detection models for special media such as acids, alkalis, and electroplating solutions in the chemical industry. Its anti-interference algorithm effectively filters impurity particles in the medium, maintaining accurate measurement even in solutions containing small amounts of contaminants. It is widely used in wastewater treatment detection in environmental chemical industries and raw material ratio control in fine chemical processes.

3. CRN56 Series: High-End Multi-Scenario Model

As the flagship model of the series, the CRN56 offers optional PTFE, Hastelloy, titanium, and other corrosion-resistant materials to adapt to stringent environments in biopharmaceutical and high-risk chemical industries. It supports 120°C in-place sterilization and high-pressure cleaning, meeting industry compliance requirements. Equipped with a multi-channel data acquisition and control system and wireless data transmission module, it meets the centralized monitoring needs of large production enterprises. It shows strong technical advantages in high-precision fields such as aerospace precision machining and high-end pharmaceuticals.
