Equipement d'analyse et regulation pour le controle de la qualite de l'eau
Analysis & Control


For drinking and industrial water quality

The DOUBLEAU is a multi-sector analyzer/controller. It allows to control the water quality of various parameters (adjustable bi-parameter measurement).

Measured parameters:

The DOUBLEAU range offers a very wide choice of measures…

  • Temperature
  • pH
  • redox (ORP)
  • active chlorine – free – total – combined
  • free bromine – BCDMH – DBDMH – sea water
  • ozone
  • chlorine stabilizer (isocyanuric acid)
  • PHMB
  • turbidity
  • conductivity
  • salinity
  • flow detector
  • flowmetry…
The DOUBLEAU offers many advantages and a great ease of use

The PLUS for your use

Many measurement parameters

Chemical calculation between several measures

Flow proportional dosing

Easy to use and install

Faults and anomalies clearly displayed

Wide choice of all-terrain probes

Connection to any type of dosing: solenoid valves, dosing pumps...
