Automatic liquid chemical dosers

VA DOS BASIC Chlorine - pH + ORP Dosing Station

A digital multi-parameter dosing station for pool water care. This automatic dosing station monitors and doses chlorine and pH on its own. A container of pH and chlorine is included. The station has a large, easy-to-read display and an IP65 protection rating. The unit features an OFA alarm to protect against overdosing.

More time for swimming, less hassle with water treatment. The VA DOS BASIC automatic dosing station continuously measures the pH and oxidation-reduction potential (ORP) of your pool water and controls the dosing of pH correction and chlorine disinfection products based on the set values.

It helps keep conditions in your pool stable and reduces the need to add chemicals by hand. You can easily check the current readings on the large, clear graphic display.

What does VA DOS BASIC offer?

• Automatic pH and disinfection control - dosing responds to the measured water values.

• Platinum ORP probe - monitors the redox potential, which the station uses to control chlorine dosing.

• Easy operation - the clear display makes checking and adjusting settings simple.

• Overdose protection - the integrated OFA alarm watches for the set dosing time being exceeded.

• Durable design with IP65 protection.

• Expansion options - for example, flow monitoring or chemical level monitoring; the corresponding sensors are not included in the basic package.

Treat yourself to easier pool water care. VA DOS BASIC takes care of regular dosing so you can enjoy your pool more.

PICO DUO - automatic pH and chlorine disinfection control

Enjoy your swim and leave the regular chemical dosing to automation. PICO DUO combines pH control and chlorine disinfection in a single unit. It continuously monitors pH and redox potential (Rx) and doses pH correction product and liquid chlorine according to your settings. It is suitable for home pools with a volume of up to 60 m³.

Dosing adapts to what the water actually needs. As the measured values approach the set target, the unit shortens the dosing time and lengthens the pauses. This way it adjusts the water gradually and helps maintain stable swimming conditions.

Why choose PICO DUO?

• Two functions in one unit - automatic pH correction and chlorine disinfection dosing.

• Less manual work - reduces the need for regular manual dosing of chemicals.

• Dosing on demand - responds to the measured values and doses less as it approaches the target.

• Simple setup - set the desired pH and Rx using the control buttons.

• Easy probe calibration - single-point calibration for both pH and Rx.

Technical specifications

Chlorine disinfection is dosed according to the redox potential, which reflects the oxidation-reduction properties of the water. It is not a direct measurement of free chlorine concentration in mg/l.

PICO DUO makes pool care easier, so you have more time to relax by the water.

VA DOS BASIC or PICO DUO?

Both stations automatically regulate pH and dose chlorine based on the measured redox potential. This makes pool water care easier and reduces manual chemical dosing.

• VA DOS BASIC additionally offers Wi-Fi connectivity for convenient remote monitoring.

• PICO DUO is our recommendation for customers who prefer simplicity and long probe life. Here at PoolPlast, our long-term experience shows better probe durability with this model.

For remote monitoring, choose VA DOS BASIC. If you trust our experience with probe durability, we recommend PICO DUO.
