Which Brand of Online Residual Chlorine Analyzer Is Better? Brand Recommendations

Online residual chlorine analyzers are high-precision instruments used to detect residual chlorine content in water samples, widely applied in various fields requiring disinfection and water quality control. This article recommends 5 brands of online residual chlorine analyzers from three categories: specialty brands, international brands, and domestic brands, to help you quickly find suitable products.

Specialty Brand Recommendation: Bebur

Bebur is a professional water quality analysis instrument brand originating from the UK. It entered the Chinese market in 2008 and established its Chinese subsidiary, Bebur Instrument Co., Ltd., in 2020 to provide localized services.Its residual chlorine analyzers feature two technical routes: the electrode method (Model: BT6308-CL) and the DPD colorimetric method (Model: BC350). They perform excellently in municipal water supply, wastewater treatment, industrial process water, and other fields. Positioned between high-end international brands and mainstream domestic brands, it offers obvious cost-performance advantages.

Bebur is a professional and reliable brand in residual chlorine analysis, especially ideal for users seeking international quality, localized service, and high cost performance. Its membrane amperometric technology excels in maintenance-free operation and stability, with a 6-month maintenance-free interval that stands out among similar products.

International Brand Recommendations: Hach, Endress+Hauser (E+H)

Hach

Hach is a global leader in water quality analysis, supporting multiple scenarios with authoritative data and complete domestic technical support.Its CL17sc / CL17Dsc online residual chlorine and total chlorine analyzers represent a new generation of intelligent water quality monitoring equipment. Based on the proven colorimetric method, they achieve accurate and reliable monitoring of residual chlorine/total chlorine through advanced automatic compensation and diagnostic technologies.The instruments feature superior anti-interference capability and user-friendly maintenance design, widely used for water quality control in drinking water safety disinfection, wastewater treatment, food and beverage, and other industries.

Endress+Hauser (E+H)

As a global leader in process automation, E+H is renowned in residual chlorine monitoring for its digital sensing technology, high integration, and strong anti-interference performance.Its sensors are designed for durability and long-term stability, suitable for continuous operation in industrial environments.E+H’s key advantage lies in seamlessly integrating residual chlorine measurement into its overall water treatment process solutions (alongside pH, turbidity, flow rate, etc.), enabling unified management and diagnostics on a single system platform. For large industrial water treatment projects already using many E+H instruments, choosing its residual chlorine analyzers ensures smooth system integration and data management.

Domestic Brand Recommendations: Luheng, Create

Luheng (Luheng Bio)

Luheng focuses on cost-effective residual chlorine monitoring equipment, supporting both DPD colorimetric and electrode methods, with a product line covering portable and online models.The instruments are affordable, easy to operate, and have low reagent and consumable costs. They can be used without professional maintenance, making them highly suitable for basic scenarios such as swimming pools, small township water plants, civil secondary water supply, and simple on-site testing.Its strengths include low cost, ease of use, and convenient after-sales service, meeting routine disinfection and residual chlorine control requirements. However, the products adopt a civil-oriented economical design, with average performance in high precision, anti-fouling capability, and long-term industrial stability. They are more suitable for non-professional monitoring scenarios with limited budgets and simple working conditions.

Create (Kruida)

Create is a well-established industrial-grade water quality analysis brand. Its residual chlorine analyzers feature mature and stable electrode technology, with high accuracy, anti-fouling and corrosion-resistant properties, long membrane life, and strong long-term operational reliability.The products adapt to complex working conditions such as power, petrochemical circulating water, municipal water supply, and industrial wastewater, supporting multi-parameter integration and remote communication, and can be connected to automated control systems. Its professional performance ranks among the top domestic brands.Priced higher than civil-oriented brands, the instruments require certain professional skills for operation and maintenance. They are suitable for industrial and municipal projects with high demands for data stability, working condition adaptability, and long-term unattended operation, with overall performance closer to industrial-grade application standards.

When selecting a residual chlorine analyzer, users should comprehensively evaluate based on specific application scenarios from multiple dimensions including measurement accuracy, response time, maintenance cost, environmental adaptability, and data transmission functions, to choose the most cost-effective product.
