Clo
FCL Free Chlorine / Chlorine Dioxide Analyzer
Free Chlorine / ClO₂
Analyzer for free chlorine and chlorine dioxide measurement in disinfection processes.
- Simultaneous free chlorine / ClO₂, pH and temperature measurement
- Reagent-free three-electrode design — very low operating cost
- Stable readings even at zero chlorine or supply interruption
Tổng quan
A free chlorine analyzer continuously measures disinfectant residual in drinking water, verifying that disinfection is effective from the treatment plant through the distribution network to the point of delivery.
The FCL Chlorine / Chlorine Dioxide Analyzer adopts a patented three-electrode measurement system (Patent No. ZL202122714794.6) capable of simultaneous measurement of free chlorine or chlorine dioxide, pH and temperature. The sensor uses an integrated panel-mounted design combining the three-electrode system with flow regulation, convenient sampling and automatic rotor cleaning. The high-purity platinum electrode features self-cleaning and requires no membrane or electrolyte, making it highly resistant to harsh environments.
Ứng dụng tiêu biểu
Tính năng
- High reliability — the three-electrode system enables accurate measurement even in challenging conditions such as zero chlorine or water supply interruption
- High accuracy — integrated pH and temperature compensation ensures precise chlorine measurements
- Low flow operation — active stirring technology allows stable measurements at flow rates as low as 0.1 L/min, with a daily water consumption of only 0.15 tons
- Self-cleaning electrode prevents fouling by sediment or colloids, significantly extending maintenance intervals
- Reagent-free design — no reagents required except for the pH electrode, resulting in low operational costs
