Chlorine analyzer Deox/2000®

sulfur dioxideprocess waterfor wastewater

Description
The Deox/2000® is an online dechlorination analyzer for continuous measurement of sulfur dioxide (SO2) and total chlorine residuals. It delivers accurate monitoring of sulfite and total chlorine in effluent streams and includes a center-zero residual analysis capability to control SO2 at a setpoint for complete dechlorination while minimizing SO2 overfeed. Systems can be configured with the SFC electronic package for single-point control or the MFC package for multi-point measurement and control.

Features

• Continuous on-line measurement of sulfite and total chlorine residuals
• Five selectable operating ranges: 0.5–10.0 mg/L for SO2 and Cl2
• Proven amperometric three-electrode measuring cell for direct residual measurement
• Performance unaffected by turbidity, temperature or conductivity variations
• Stable chloramine-T reagent for generation of the iodine bias
• Low-flow sample cell design for economical reagent consumption

Benefits

• Fast response time for precise control and monitoring of rapid water-quality changes
• Prevents costly chemical overfeed by monitoring sulfite residuals
• Separate flow cell and electronic packages provide installation flexibility

Applications

• Boiler feedwater
• Cooling tower water treatment
• Equipment washing and sanitization
• Industrial pretreatment
• High-purity water treatment
• Chloramination control
