Endress+Hauser disinfection sensors for chlorine dioxide, free chlorine, total chlorine, free bromine and dissolved ozone make use of this amperometric measuring principle.

Real-time measurement technology allows for immediate responses to process changes, optimizing the dosing of disinfectants and reducing costs. A unique feature of these chlorine sensors is their ability to remain active and ready to measure as soon as chlorine is detected, even after extended periods without chlorine, unlike other sensors that struggle to provide accurate readings after such intervals.

The following ensure even more simplicity, leading to cost savings:

• Reagents are not required: No costly reagents are required using the amperometric measuring principle. This also eliminates the need for their disposal and the associated workload.

• Faster polarization time: The optimized polarization time means that the disinfection sensors reach a stable display value faster after commissioning. This reduces system downtime and extends production uptime.

• Low maintenance requirements and predictive maintenance: In addition to the Memosens 2.0 predictive maintenance capabilities, robust components ensure that the sensors themselves are low maintenance. One example is the convex membrane made of dense and stain-resistant material.
