Free & Total Chlorine in Power Generation

At Alpha, our free & total chlorine sensors are specifically designed for power generation applications, providing robust, accurate, and customizable solutions. Our sensors feature:

Robust Design: Constructed from durable materials like PVC, CPVC, ABS, and Ryton.

High Accuracy and Resolution: Accuracy of 0.2 ppm or 4%, as well as a resolution of 0.01 ppm.

Wide Measurement Range: Adjustable from 0-2 ppm to 0-100 ppm.

Optimized Flow Rate: Functions efficiently with flow rates between 30 L/hr and 60 L/hr.

Integrated Temperature Compensation: Ensures consistent performance across 0 to 50°C.

Output Flexibility: Supports both analog (4-20 mA or 0-5 V) and digital (RS-485 MODBUS RTU) outputs.

Free Chlorine Sensor in Power Generation

Accurately measuring free chlorine with the RC68 sensor in cooling towers is vital for maintaining system efficiency and preventing microbial growth. Free chlorine acts as a potent disinfectant, killing bacteria and algae that can form biofilms on heat exchange surfaces.
