MDS-BG

Product Introduction

The MDS-BG series multi-parameter water quality analyzer is a practical, highly modular sensor developed for the water supply and swimming pool industries. Utilizing the latest technology, the main module can simultaneously connect to four probes, allowing for the selection of nine monitoring factors (residual chlorine, carbon dioxide, total chlorine, turbidity, pH, temperature, conductivity, oxidation-reduction potential, and dissolved oxygen). External flow and pressure sensors are also available. Residual chlorine (carbon dioxide) is measured using a membrane-free three-electrode method, with electrodes including high-purity platinum (gold). Turbidity is measured using a 90 ° scattering light principle, with a long-life, stable LED light source. pH uses a glass electrode; conductivity uses a four-electrode graphite electrode; and dissolved oxygen uses a fluorescence method. The sensor features RS485 output, standard MODBUS RTU protocol, and supports networking with various terminals. 

The entire instrument uses no chemical reagents, eliminating secondary pollution. Residual chlorine consumables only need replacement every 2-3 years. The instrument includes a mechanical rotor self-cleaning system, suitable for high-hardness, dechlorination, and water-shortage conditions, enabling long-term, low-maintenance operation.

Product Advantages

1. Integrated design for convenient and quick installation and maintenance;

2. Supports water-saving (interval measurement) mode, with adjustable measurement intervals and time parameters, offering long-term, low-maintenance performance;

3. The turbidity monitoring system features pressure-holding to suppress bubble precipitation, eliminating interference from bubbles in turbidity measurements.

4. Residual chlorine (chlorine dioxide, ozone) measurement utilizes an integrated ARM processor and a high-efficiency filtering algorithm to avoid noise interference effectively.

5. Expandable, with the disinfectant sensor supporting free switching between residual gas (chlorine dioxide) and ozone measurement modes without hardware replacement;

6. The instrument has a lock screen password, which the administrator can set.

7. Low operating and maintenance costs, requiring no reagents and causing no secondary pollution;

8. Features power outage protection, automatic power recovery, system diagnostics, and alarm functions;

9. Optional wireless module supporting 4G full network wireless transmission;

10. Supports both AC (220V AC) and DC (12-24V DC) power supply modes.
