Product Overview
The DR-4500 series is a high-cost-effective multi-parameter water quality analyzer developed for tap water, secondary water supply, swimming pool water, etc. It adopts advanced sensor measurement and automatic cleaning technology to achieve real-time and accurate measurement of multiple parameters such as turbidity, residual chlorine/chlorine dioxide, pH, and temperature, fully ensuring the safety of residents’ water use.
Key Features
Accurate Data
- Equipped with a turbidity sensor with an independent steady-flow defoamer, automatic light source compensation, light window defogging, and automatic sewage discharge equipment.
- Configured with a constant-voltage three-electrode residual chlorine sensor for stable measurement.
- The water circuit adopts a steady-flow design for more stable flow rate.
Corrosion Resistance and Anti-interference
- The cabinet body is made of 304 stainless steel with plastic spraying treatment, having good corrosion resistance and anti-electromagnetic interference performance.
- The cabinet body adopts a double-chamber design for water and electricity separation, ensuring high safety.
High Expandability
- Modular design, standard configuration of turbidity, residual chlorine/chlorine dioxide, pH, and temperature.
- Can easily expand parameters such as ORP, dissolved oxygen, conductivity, and TDS.
- Supports more customized functions, such as battery power supply and wireless transmission.
Easy Installation and Simple Operation
- The sensor, preprocessing, and display & transmission are highly integrated in one cabinet for plug-and-play water circuit.
- Adopts a 7-inch touch screen with a beautiful interface and simple operation.
Low Maintenance
- Turbidity automatic sewage discharge and automatic flushing.
- The sensor is equipped with quick-connect joints for convenient and rapid disassembly and maintenance.
- Residual chlorine adopts electrochemical cleaning + mechanical cleaning to ensure the cleanliness of the electrode surface.
Water and Power Saving, Low Operating Cost
- Adopts a water circuit series design, allowing the selection of intermittent water inlet measurement mode with less water consumption.
- The sensor adopts a low-power design.
- No need for chemical reaction reagents and no need to replace the residual chlorine sensor.
