Conex® DIA-2, DIA-2, DIA-2Q
Measuring Amplifiers and Controllers
One or two Parameters: Cl2, ClO2, O3, H2O2, PAA, pH, redox (ORP)
Measuring amplifiers and controllers
Preassembled systems
The Conex® DIA (Dosing Instrumentation Advanced) series is
designed for users without previous knowledge.
A simple plain-text menu allows you to complete your tasks
quickly and easily without wasting any time on learning
and deciphering codes. The units speak no less than nine
languages, allowing virtually anyone to navigate the selfexplanatory menus. ­Conex® units monitor themselves,
ensuring high water quality at all time.
DIA preasssembled systems combine controllers and triedand-tested electrodes on a plate ready for quick installation.
Conex® DIA comes in three versions:
• Conex® DIA-1: Universal measuring amplifier and
controller
• Conex® DIA-2: Dual measuring amplifier and controller
• Conex® DIA-2Q: Dual measuring amplifier and
multifunction controller
Features
• The calibration function carries out a plausibility check to
prevent mishaps
• The logbook function records sensor data and calibration
values complete with date and time
• The units also keep an eye on the temperature and make
adjustments as necessary
• Nine display languages: German, English, French, Spanish,
Italian, Portuguese, Dutch, Polish, Russian
The system is equipped with one of these controllers:
• Conex® DIA-1: for chlorine (Cl2), chlorine dioxide (ClO2), or
ozone (O3)
• Conex® DIA-2: chlorine (or chlorine dioxide or ozone) and
for pH
• Conex® DIA-2Q: chlorine (or chlorine dioxide or ozone) and
for pH (or redox potential)
The system is equipped with one of these AquaCells:
• D11, pressure-proof, with cleaning motor
• D12, pressure-proof, with hydro-mechanical cleaning
• D13, pressureless, with hydro-mechanical cleaning
Features
• Prepared cable sets
• Measuring cell for chlorine, chlorine dioxide or ozone
• Optional pH electrode
• Temperature compensation
