Commercial Cooling Tower
Chlorine Analyzer

Monitoring residuals in commercial cooling tower applications is not an easy problem. Many systems operate at high cycles of concentration due to the conductivity and hardness found in water. To slow the formation of build-up, many operators use film-forming corrosion inhibitors. The resulting organic contaminants make it difficult to read chlorine levels in the system’s water. HSI’s MP5™  chlorine sensor is ideally suited for these challenging applications. Not only can it measure chlorine OR bromine, but the SensiCLĒNE™ technology cleans the electrodes continuously to prevent film build-up.

Halogen’s MP5™ is well suited for monitoring cooling towers in open- or closed-loop systems, as well as closed-circuit systems. Just one MP5™ can monitor free chlorine, pH, temperature, conductivity, and ORP. Because the MP5™ is unaffected by turbidity, flow, or pressure, it can be placed inside a closed loop, in a dead leg, or near an intake or discharge valve.

The MP5™is compact, sturdy, and does not use membranes, electrolyte, or reagents. Unlike the older technologies used in other amperometric sensors, the MP5™ analyzer is self-cleaning and unaffected by changes in flow, pressure, or temperature. It also automatically compensates for changes in pH and doesn’t lose calibration if dried out.
