Water analyzer DEPOLOX® 400 M

processfor boilerfor wastewater

Overview
Online process analyzer for continuous measurement of disinfectant concentration and common water-quality parameters in clean water applications. Designed for straightforward integration into industrial and municipal monitoring systems.

Key features

• Intuitive operation and clear visualization of measured parameters via a 4" color touch panel
• User-configurable calibration-check intervals and service reminders
• Fast response disinfectant measurement using DEPOLOX® bare electrode technology (DEPOLOX 5 C Flow Cell)
• Alternative membrane-based amperometric option: VariaSens™ C sensor
• Communication interfaces: Ethernet (with built-in web visualization on local networks), RS-485 and four 4–20 mA outputs for integration
• Measurement data logging with easy export and access from remote or mobile devices
• Programmable LED-lit flow cell for visual indication on alarm or fault

Description
Evoqua's DEPOLOX® 400 M analyzer offers operators a simple, intuitive touch-panel interface to monitor up to three established measurement parameters: a disinfectant (free or total chlorine, chlorine dioxide ClO2, ozone O3, or potassium permanganate KMnO4) plus secondary parameters such as pH, ORP (redox), fluoride and temperature. The instrument is available with two amperometric disinfectant measurement technologies: the fast-reacting DEPOLOX 5 C Flow Cell (bare electrode) and the membrane-based VariaSens™ C. Integration and communication options support process control and data acquisition workflows.
