Waterlink Hydro Touch | Automatic Pool Chemical Dosing
Precision Chlorine & pH Control for Swimming Pools
Take the guesswork out of swimming pool water treatment with the Waterlink Hydro Touch Automatic Chemical Dosing System.
Designed for residential and light-commercial swimming pools and spas, Hydro Touch continuously monitors water chemistry and automatically controls sanitiser and pH dosing to help maintain stable, consistent pool water.
With an easy-to-use 3.5" touchscreen, proportional dosing control and a choice of ORP or Free Available Chlorine (FAC) monitoring, Hydro Touch provides pool owners and operators with a professional automatic chemical control solution without the complexity of a large commercial dosing system.
Suitable for pools and spas up to 160,000 litres, Hydro Touch is an excellent option for premium residential pools as well as swim schools, hotels, resorts, wellness facilities and other light-commercial aquatic applications.
Key Hydro Touch Features
Waterlink specifies these control, safety and monitoring capabilities for the current Hydro Touch range.
These features and available upgrade options are specified in Waterlink's current Hydro Touch documentation.
Automatic Chlorine & pH Control
Correct chlorine and pH levels are critical to maintaining clean, comfortable and properly balanced swimming pool water.
Instead of relying solely on manual chemical adjustment, Hydro Touch uses dedicated sensors to monitor the water and automatically control chemical dosing according to the configured set points.
Depending on the selected model, Hydro Touch can control liquid chlorine dosing or an existing salt chlorinator, while automatically dosing diluted liquid acid for pH control. The result is more consistent water chemistry and considerably less day-to-day manual adjustment.
Waterlink describes the system as providing automatic pH and sanitiser control with self-diagnostic capabilities and overfeed alarms to help ensure correct chemical feed rates.
ORP or Direct Free Chlorine Monitoring
One of the key advantages of the Hydro Touch range is the ability to select the control method appropriate to the installation.
Hydro Touch ORP Control
The ORP models monitor Oxidation Reduction Potential (ORP/Redox) and use this measurement to control sanitiser production or dosing.
Hydro Touch can be configured either to operate an existing salt water chlorinator through a GPO output or to directly dose liquid chlorine using its onboard peristaltic pump.
This makes Hydro Touch particularly useful when upgrading an existing swimming pool where a compatible salt chlorinator is already installed.
Hydro Touch FAC Control
For installations requiring direct chlorine measurement, Hydro Touch is also available with a Free Available Chlorine (FAC) sensor.
FAC models can be supplied for salt chlorinator control or with dual dosing pumps for direct liquid chlorine and acid dosing.
Four Hydro Touch Configurations
Waterlink offers Hydro Touch in four primary configurations:
CHYT0454AU
ORP · Salt chlorinator/GPO · Liquid acid
CHYT0444AU
ORP · Liquid chlorine pump · Liquid acid
CHYT0434AU
Free Chlorine/FAC · Salt chlorinator/GPO · Liquid acid
CHYT0433AU
Free Chlorine/FAC · Liquid chlorine pump · Liquid acid
The one-pump versions are designed to control a separate chlorinator while dosing acid, whereas the two-pump versions provide onboard dosing for both liquid chlorine and acid.
Aqua Clear can help specify the correct Hydro Touch configuration to suit the pool, sanitising system and application.

Spas & Wellness Centres
Suitable for pools and spas where reliable chemical monitoring is essential.
Body Corporate & Shared Pools
Reliable automatic chemical monitoring for shared aquatic facilities.
Water Features & Splash Areas
Fountains, water features and children's splash and wet-play areas.
Optional Remote Monitoring
Hydro Touch can also be upgraded with a Waterlink modem for remote monitoring, providing an additional level of oversight for commercial facilities, service companies and professionally managed pools.
Additional upgrade options include an FAC probe, flow switch, temperature measurement, tank-level monitoring and alarm relay.
Why Install Automatic Pool Chemical Dosing?
Automatic chemical control doesn't eliminate the need for regular professional water testing, but it can significantly reduce the fluctuations that occur between manual chemical adjustments:
- More consistent water chemistry – automatically responds to changes in sanitiser demand and pH.
- Reduced manual chemical handling – less reliance on manually measuring and adding chemicals.
- Improved swimmer comfort – more stable pH and sanitiser levels help avoid large swings in water chemistry.
- Better chemical control – proportional dosing helps prevent unnecessary chemical addition.
- Simpler pool management – particularly valuable for larger residential pools and light-commercial facilities.
Importantly, Waterlink recommends that automatic dosing does not replace regular manual water testing; periodic testing remains necessary to verify water balance and account for seasonal changes.
