Which brand of refractometer is recommended for inline electrolyte concentration detection?

As a core raw material in industries such as lithium batteries, capacitors, and electroplating, the precise and stable control of electrolyte concentration directly determines the core quality of end products and is also a critical step in avoiding safety risks during production. Traditional manual sampling and testing methods are not only inefficient, with serious delays in data feedback that cannot match the pace of modern continuous production, but also pose significant safety risks to operators due to the strong corrosiveness, volatility, and flammability of electrolytes.

With the intelligent and refined upgrading of industrial production, the Inline Refractometer (online concentration detector), relying on its advantages of real-time, high-precision, and unmanned detection, has become the mainstream preferred equipment for online electrolyte concentration monitoring and control, and a core standard configuration in the quality control process of electrolyte production. Choosing a high-quality Inline Refractometer that is suitable for electrolyte operating conditions means selecting stable and reliable quality assurance for the production line, and is also a core prerequisite for improving quality, reducing costs, and ensuring safe production.

I. Dedicated requirements for electrolyte operating conditions: three core criteria for Inline Refractometer selection

The chemical properties and production process standards of electrolytes determine that their requirements for Inline Refractometers are far higher than those of ordinary working conditions. A qualified online electrolyte concentration detector must meet three core conditions—corrosion resistance, accuracy, and adaptability—none of which can be missing. These are also the core basis for selection:

1. Extreme corrosion resistance, suitable for complex corrosive electrolyte conditions

Electrolytes often contain strong acids, strong alkalis, and various organic solvents, placing stringent demands on the corrosion resistance of detection equipment. A qualified Inline Refractometer must have core wetted parts with excellent corrosion resistance and anti-scaling performance, capable of long-term resistance to electrolyte corrosion, preventing component damage and detection failure, ensuring stable operation of the equipment, and reducing failure rates and maintenance costs.

2. High precision + high stability, matching stringent electrolyte quality control standards

Electrolyte concentration control is often based on per-mille (‰) level standards, and even slight concentration deviations can lead to increased defect rates. A high-quality Inline Refractometer must offer ultra-high concentration detection accuracy and be equipped with a comprehensive fully automatic temperature compensation function, ensuring drift-free, precise, and stable detection data across the wide operating temperature range of the production line, thereby controlling concentration standards from the source.

3. High adaptability, closely aligned with actual production line requirements

It must support 24-hour uninterrupted real-time online detection, offer flexible installation without modifying the production line, allow customized calibration curves for different electrolyte formulations to solve the industry pain point of inaccurate detection of special formulas, provide explosion-proof certified models in line with safety production standards for lithium battery and chemical workshops, and seamlessly connect to production line PLC systems to enable automatic concentration control. These are the core requirements for adapting to electrolyte production lines.
