Arka – Residual Chlorine Meter Set AI340

Our Residual Chlorine Analyzer accurately measure the remaining (residual) chlorine concentration in treated water. This analyzer operates without the need for reagents, offering low maintenance and long-term stability even in challenging water conditions. Designed for use in potable water, cooling towers, wastewater effluent, RO pre-treatment, and industrial process water, this system ensures that residual chlorine levels stay within safe and compliant limits — protecting both infrastructure and public health.

Features

• Wide Measuring Range: 0–20 mg/L (ppm) : Ideal for standard and high-range disinfection applications.
• High-Accuracy Amperometric Sensor : Provides reliable, real-time residual chlorine measurements with fast response.
• Reagent-Free Operation : Low operating cost and minimal maintenance — no need for DPD or chemical reagents.
• Automatic Temperature Compensation : Built-in temperature sensor ensures accurate readings under varying process conditions.
• Optional pH Compensation : Supports external or integrated pH sensor input for accurate chlorine readings in variable pH water.
• Digital Display Unit : OLED display for real-time chlorine, temperature, and system status information.
• 4–20 mA Output + RS485 (Modbus) : Standard industrial outputs for integration with PLC, DCS, or SCADA systems.
• Configurable Alarm Relays : High and low chlorine setpoints with relay outputs for process control or safety shutdown.
• Wall or Panel Mount Options : Flexible installation to suit any plant layout or enclosure.
