Why Halogen
Find your application
Consider final residual, challenging water, chloramination and reservoir monitoring.
Explore applicationsLess routine work.More useful context.
The strongest advantages come from the complete system: measurement, cleaning, installation and the information available to the operator.
Reagentless
No analytical reagents, membrane or electrolyte to replenish. Routine service and wear parts still apply.
Self-cleaning
Mechanical cleaning and electrochemical surface renewal help manage deposits at the sensor.
Flexible installation
Review suitable in-pipe, immersion or flow-cell arrangements against the exact model and site conditions.
Connected context
Integrated water-quality measurements and controller options help bring the residual into your operating routine.
Free chlorine or monochloramine?
Start with the disinfectant species you need to follow. A total-chlorine value does not identify monochloramine on its own.
PMA can help confirm the sensor generation, measurements and installation for your water. Product options and operating limits are confirmed for the exact supplied model.
Challenging water leaves its mark.
These are the photographs used in PMA’s published MP5 field-trial account. They show deposits on the outer cap, inside the flow cell and at the sensing end.
Begin with your water.

Installation
Inline, immersion or flow cell: choosing a chlorine sensor installation
Compare inline, immersion and flow-cell chlorine monitoring. Consider sample-water waste, zero-flow duties, response, service access and plant integration.
Read the articleA few useful answers.
Does reagentless mean maintenance-free?
No. Cleaning media, wear parts and routine verification still need attention. Follow the maintenance schedule for the selected sensor.
Which analytical consumables are removed?
The measurement uses no analytical reagents, membrane or electrolyte. Service components and cleaning media remain part of the system.
Can the sensor work without external flow?
Integral circulation supports suitable zero-flow and variable-flow applications within the selected sensor’s rated operating envelope.
What site conditions should I check?
Review water chemistry, temperature, pressure, mounting and service access with PMA before selecting the installation.
Are MP6 and MP-TOTAL the same specification?
Do not assume that they are. Legacy MP6 and current MP-TOTAL material describe different parameter sets and generations.
How do I choose the correct model?
Start with the disinfectant you need to measure and your application. PMA can confirm the exact product and controlling datasheet before supply.
