W510--DCL4.2MA10 Free Chlorine Sensor Applied in Foot Bath

W510--DCL4.2MA10 applied in Foot Bath for Residual Chlorine Monitoring

A large chain swimming pool (serving over 500 daily swimmers) uses foot baths as a primary hygiene barrier, requiring free residual chlorine to stay within 5–10mg/L per GB 37488-2019. Previous management faced critical issues:
•Unreliable manual dosing: Twice-daily chlorine powder dosing led to imbalances—<5mg/L (incomplete sterilization) on weekdays, >12mg/L (3 skin irritation complaints) on weekends.
•Inaccurate traditional monitoring: Sensors had ±0.5mg/L deviation (expanding to ±0.8mg/L with temperature swings), causing false readings (e.g., 10.5mg/L measured as 9.8mg/L, exposing 200+ swimmers to substandard water).
•Disruptive maintenance: Corrosion from high chlorine and 90% humidity required monthly disassembly/calibration (2x/month), halting foot baths for 1 hour each time (annual cost: ~¥12,000).

W510--DCL4.2MA10 Solution
Tailored to foot baths’ high-concentration, high-humidity, and high-usage conditions, its key features form a closed-loop system.

Application Outcomes
Post-deployment with auto-dosing linkage:
•Stable concentration: Residual chlorine stabilized at 6–9mg/L (fluctuation from ±5mg/L to ±0.3mg/L), ensuring sterility (no pathogens in monthly tests) and zero irritation complaints.
•Faster response: Over-limit alerts cut from 30 mins (manual testing) to 1 min; 5 potential overages intercepted (e.g., 10.2mg/L → 9.8mg/L in 5 mins via auto-dilution).
•Cost savings: Annual maintenance costs dropped 85% (¥12,000 → ¥1,800); 20% less disinfectant saved ~¥6,000/year.
•Compliance: Auto-stored data/reports met health authority requirements, earning "Pool Hygiene Management Demonstration Unit."
W510--DCL4.2MA10, with accurate high-concentration measurement, strong durability, and low maintenance, ensures efficient sterilization and safety, strengthening swimming pool hygiene.
