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 provides accurate and stable measurements without the need for chemical reagents.
Why choose the ECLG-35?
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 on Ø50 mm tubing.
Priority to safe, clean water
With reagent-free operation, built-in cleaning, and excellent measurement stability, the ECLG-35 ensures accurate, long-term chlorine control, eliminating the need for routine maintenance or consumables—ideal for utilities and facilities where a safe and clean water supply is a top priority.
The Residual Chlorine Meter ECLG-35 is ideal for use in water treatment plants, distribution networks, buildings, hospitals, hotels, and the 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.
