Complete, compact pH- or pH+ regulator

Stér-pH Universal regulates the pH level by injecting a pH- or pH+ corrector solution.

The acidity (pH) of pool water is a parameter that impacts the effectiveness of water treatment and user comfort.
Stér-pH U is an automatic pH analyser and regulator which offers proportional pH regulation using a peristaltic pump that injects a pH- or pH+ corrector solution.

The pH level of your pool is managed precisely and simply.

Product benefits

  • Very easy to install and adaptable to all filtration systems.
  • View all parameters at a glance.
  • Buttons for simple configuration.
  • Long sensor life thanks to dual-function sensor for higher measurement quality and longer service life.
  • Can be configured to use pH+ or pH- for regulation.
  • Adjustable to the largest pools, up to 300 m3.
  • Economical: as regulation is proportional, the quantity of product injected is calculated using the difference between the measurement and the set point.
    The pH is then stabilised and product consumption reduced to a bare minimum.

pH +/- regulation:

Choose the regulation mode without opening the unit.
Value readings to +/- 0.1 pH.

Overdose safety:

In case of overdose, a built-in safety mechanism uses an alarm lamp.

Proportional regulation:

Product injection time is calculated according to the observed change in the measurement.

Low product level sensor:

If the pH set point is not reached in a specified time, the system puts itself into Standby safety mode.


To inform the user whenever necessary, a diagnostic code automatically appears on the appliance screen.
Each code refers to an explanation in a table incorporated in the user manual. The explanations enable users and technicians to understand and resolve issues, even remotely.
