## Chlorine measuring has evolved !

- No more gel or membrane, no maintenance burden
- No reagent or expensive service contract...
- No water loss, no sample stream to dispose of

Total peace of mind : reliable measures, extended calibration stability, in-pipe option, battery power option, easy IoT integration,...

## A technical innovation... leading to a product revolution !

Sometimes it is good to reinvent the wheel ! 

By revisiting a 20 year old way to measure chlorine levels in drinking water, for a project where monthly maintenance was just not possible, Halogen Systems did not simply improve an old concept : it set a new standard for amperometric measuring.

### In-pipe

### Flow cell

### Immersion

### PVC pipe

### No bypass, no waste stream

No piping needed, don't waste a drop

### No reagent, no gel, no membrane

Reduce maintenance, don't waste hours

### No pressure adapter, no pump

Designed for in-pipe metering

### Increased stability & accuracy

Extended calibration persitence

### Still water is fine

The embedded impeller regulates a constant flow

### Easy integration with 3rd party systems

Supports Modbus RTU communication

### Halogen Systems app

Check water quality directly from your phone

### Extended sensor lifetime

Changing the electrodes after 5 years is a 2 minutes field maintenance

## The technology behind Halogen Systems' chlorine sensors

No gel ! No membrane ! 

Our sensors use solid electrodes, not coated ones.  They are in direct contact with the water and the embedded pump ensures a constant flow across the sensor head.
