Automatic pH adjustment and disinfectant dosing system

Dosing pumps water treatment


PH.DOS is the ideal dosing system for adjusting and dosing pH and injecting any type of disinfectant.

The pH meter and the programmer for the injection of the disinfectant are integrated inside an ABS IP65 housing, thus guaranteeing a perfect seal. The display is digital.

The electronics incorporate an overdose prevention function and a proportional mode, via timing, for liquid pH injection. PH.DOS allows dosing of disinfectant from 1 to 999 ml.

Disinfectant injection is programmed each time the unit is started up and can, on request and depending on the type of disinfectant, be programmed hourly.

The 2 l/h peristaltic dosing pumps are independent of the electronics, ensuring the longevity of the system even in the event of leaks in the dosing chambers.

Compact and mounted on an easy-to-install panel, PH.DOS is particularly suitable for pools equipped with a U.V. system that requires, in addition to permanent pH adjustment, the injection of low-dose disinfectant.

PH.DOS is sold and shipped with a kit consisting of:

  • Electronic control panel;
  • N.2 peristaltic pumps;
  • pH probe with 5 metre cable;
  • Probe holder, foot filter and N.2 injection tubes;
  • N.2 crystal tube for suction/discharge 5 metres long;
  • Buffer solutions pH 7.0 and 4.0;
  • Wall mounting kit and spare fuse kit;
  • Instruction manual.

Please note that all material is covered by a 2-year warranty, except for the probes, valid only with installation and first start-up carried out by an authorised professional.
