Recommended domestic brands: Lu Heng, Keruida

Lohand Environemnt specializes in cost-effective residual chlorine monitoring equipment that integrates both DPD colorimetric and electrode methods, offering product lines spanning portable and online models. The instruments feature affordable pricing, intuitive operation, low consumable reagent costs, and require no professional maintenance, making them ideal for basic applications such as swimming pools, small-scale water treatment plants in rural areas, residential secondary water supply systems, and simple on-site testing. Their advantages include low cost, ease of operation, and convenient after-sales support, effectively meeting routine residual chlorine control needs for disinfection processes. However, the products prioritize cost-effective consumer-oriented designs, demonstrating average performance in high precision, pollution resistance, and long-term industrial stability. They are particularly suitable for non-professional monitoring scenarios with limited budgets and simple operational conditions.

Createc

Createc is a veteran industrial-grade water quality analysis brand. Its residual chlorine analyzers leverage mature electrode-based technology as their core advantage, featuring high precision, anti-pollution resistance, corrosion resistance, long-lasting membrane components, and robust long-term operational reliability. The products are compatible with complex industrial environments including power generation, petrochemical circulating water systems, municipal water supply networks, and industrial wastewater treatment facilities. Supporting multi-parameter integration and remote communication capabilities, they can be seamlessly integrated into automated control systems, with professional performance ranking among top domestic brands. While priced higher than consumer-grade models and requiring specialized maintenance expertise, these instruments excel in industrial and municipal applications demanding data stability, operational adaptability, and long-term unattended operation. Their comprehensive performance closely aligns with industrial-grade application standards.

When selecting residual chlorine analyzers, users should conduct comprehensive evaluations based on specific application scenarios, considering multiple dimensions such as measurement accuracy, response time, maintenance costs, environmental adaptability, and data transmission capabilities, to choose the most cost-effective product.
