Detailed Advantages for Your Application
Fully Automatic Operation: The system continuously monitors chlorine levels and automatically adjusts dosing pump speed to maintain the setpoint, eliminating manual intervention and reducing chemical waste.
High-Accuracy Sensor: Our amperometric sensor (or optional DPD colorimetric) provides stable, drift-free measurements even in dirty or turbid wastewater, ensuring reliable control.
Corrosion-Resistant Design: All wetted parts are made of PP/PVC or PTFE, suitable for aggressive chemical environments commonly found in industrial wastewater.
User-Friendly Interface: The touchscreen display shows real-time chlorine concentration, pump status, alarms, and historical data. Operators can quickly change parameters or calibrate the sensor.
Flexible Communication: Standard 4-20mA and RS485 outputs allow integration with SCADA, PLC, or remote monitoring systems, enabling centralized control.
Standard Compliant: Designed to meet international environmental regulations (e.g., EPA, local standards). Our factory holds certification for quality management.
Lower Total Cost of Ownership: Automatic dosing reduces chemical overuse, and robust components minimize maintenance downtime. Customer-configurable alarm thresholds help prevent compliance violations.

Frequently Asked Questions
Q: What types of chlorine are measured?
A: Our system measures free chlorine (HClO/ClO⁻) or total chlorine, depending on sensor configuration. For combined chlorine, a DPD method can be integrated.
Q: Can the system handle high solids or turbidity?
A: Yes, our sensor is designed with self-cleaning options (manual or automatic) to function in wastewater with suspended solids up to 500 ppm. Pre-filtration is recommended for very high loads.
Q: Is the dosing pump included? What type is it?
A: Yes, the system includes a diaphragm dosing pump with adjustable stroke length and stroke frequency. Other pump types (peristaltic, gear) are available upon request.
Q: What is the operating temperature range?
A: The standard unit operates between 0°C and 50°C for the water sample and 0–40°C for the controller. For higher temperatures, an optional high-temperature version is available.
Q: Does it require daily calibration?
A: No. The sensor typically requires calibration once per week using a standard solution. The controller offers auto-calibration prompts to simplify maintenance.
Q: Can I monitor remotely?
A: Yes, the RS485 Modbus output allows connection to a remote SCADA or IoT gateway. We can provide our own cloud monitoring software as an optional upgrade.
Q: What certifications does the system have?
A: Our manufacturing facility is certified. The product is designed to comply with applicable CE and RoHS standards, but specific certificates are available upon request.
Q: What is the delivery time?
A: Standard models are typically shipped within 15–20 working days after order confirmation, depending on quantity and customizations.
