Pool water quality directly affects swimmer health and equipment longevity. Manual testing with test strips or handheld meters provides only snapshots—conditions change between tests. A continuous online monitoring system delivers real-time data, enabling immediate corrective action before water quality drifts outside safe ranges.
The World Health Organization (WHO) recommends pH between 7.2–7.8 for effective disinfection and swimmer comfort. Free chlorine should remain at 1.0–3.0 mg/L for domestic pools, while turbidity must stay below 1.0 NTU—ideally under 0.5 NTU for crystal clarity. These parameters are interdependent: pH outside the optimal range reduces chlorine efficacy, while high turbidity shields microorganisms from disinfection.
Parameter | Range | Resolution | Accuracy |
|---|---|---|---|
Turbidity | 0–20 NTU (default) | 0.001 NTU | 0–100NTU: 2% or ±0.02NTU |
Residual Chlorine | 0–5 mg/L (default) | 0.001 mg/L | ±5% or ±0.05mg/L |
Ozone | 0–5 mg/L (default) | 0.001 mg/L | ±5% or ±0.05mg/L |
pH | 0–14 | 0.01 | ±0.1 |
Temperature | -5–60°C | 0.1°C | ±0.5°C |
ORP | ±2000mV | ±1mV | ±20mV |

The system monitors turbidity, disinfectants (residual chlorine, chlorine dioxide, ozone), pH, temperature, conductivity/TDS, and ORP simultaneously. This eliminates the need for multiple standalone instruments, reducing both capital expenditure and maintenance complexity.
In tap water (0.1–1 NTU) and pure water (0.001–0.1 NTU) ranges, the system delivers long-term stability and accurate measurement. Turbidity resolution reaches 0.001 NTU—essential for detecting subtle changes that affect water clarity and disinfection efficacy.
Core sensors and instrumentation components are sourced from high-quality imported suppliers, with internal optimizations specifically designed for online water quality analysis. The integrated structure features unified inlet/outlet interfaces, centralized data display, and wall-mountable design that prevents flooding and ground moisture intrusion.
Standard RS485 Modbus-RTU communication protocol and 4G wireless data transmission enable seamless integration with the “Water Quality Cloud Platform” and mobile terminal access. The cloud platform provides open APIs supporting third-party system integration—ideal for facility management networks and smart city infrastructure.
