1. GENERAL INFORMATIONS
Electronic instruments controlling electrochemical parameters such as pH, Redox or Chlorine are
widely used in swimming pools, waterworks and water treatment plants.
The eSelect Series Controllers stand out for the following features:
Capability of performing the most possible measurements with just one type of electronic
board: pH, Redox (mV), Cl (ppm).
Simple and easy to learn programming procedure providing two types of menu: a SIMPLE
menu allowing the user to control indispensable functions, and a EXPERT menu giving the
user the full capability of setting all functions.
Galvanically isolated electronics providing a high level of immunity to disturbances.
