The ECLG‑35 Residual Chlorine Meter is a high-precision, reagent-free sensor designed for continuous monitoring of free residual chlorine in drinking water and industrial water systems. Utilizing a 3-electrode pulse voltammetry method, the ECLG-35 offers accurate and stable measurements without the use of chemical reagents, significantly reducing operational costs and environmental impact. The sensor features an advanced automatic cleaning system, combining bead flow and electrolytic cleaning to maintain consistent sensitivity and minimize drift over time. With a measuring range of 0.00–3.00 mg/L, high repeatability (±2% FS), and a fast response time (T90 ≤ 1 minute), the ECLG-35 ensures reliable chlorine control under varying water conditions. This unit is equipped with automatic temperature compensation and a built-in thermistor, ensuring stable performance across a wide pH and conductivity range. Installation is flexible: wall-mounting is standard, or optional pipe-mounting is available on Ø50 mm tubing. Ideal for use in water treatment plants, distribution networks, buildings, hospitals, hotels, and food or pharmaceutical industries, the ECLG‑35 provides peace of mind in water safety and regulatory compliance — all while operating without consumables or complex maintenance procedures. If you need a durable, low-maintenance chlorine meter that delivers long-term accuracy and efficiency, the ECLG‑35 is the wise choice.
