Water analyzer W781-AF304

acidsignalmonitoring

Product Overview
Our Peracetic Acid (PAA) Analyzer is a robust, precision-driven online monitoring solution built with 304 stainless steel for exceptional corrosion resistance—ideal for harsh industrial environments. Available in Regular Temperature (max 45°C) and High Temperature (up to 60°C) models, it delivers accurate PAA concentration measurements via a durable membrane current two-electrode system. Enhanced with an intuitive touchscreen interface, it simplifies real-time data monitoring, parameter adjustments, and system diagnostics—no complex coding required. With rapid response times, dual-channel flow cells (pH-electrode compatible), and IP68/IP65 protection, it integrates seamlessly via 4-20mA/Modbus RS485 signals. Perfect for food/beverage sanitization, pharmaceutical sterilization, water treatment, and industrial cleaning, this analyzer combines reliability, flexibility, and long-term durability to support critical process monitoring.
