EUTECH INSTRUMENTS ALPHA CON 1000 CONDUCTIVITY CONTROLLERTRANSMITTER (REVISION 3) Manuale Utente Scaricare il pdf (Pagina 8)

pH/ORP, two-in-one Controller (software

selectable) for pH or ORP measurement modes.

Special Symmetrical configuration mode to

facilitate operating in environments with

electrical interference. Custom pH or ORP sensors

are available with the potential matching pin

for Symmetrical mode measurements.

In the ORP mode, the alpha pH 2000 is able to

measure in mV or as % concentration, with

independent calibration modes. All parameters

can be operated in the asymmetrical or

symmetrical mode.

With a pH and ORP controller side-by-side,

controllers can be operated in a master-slave

operation where pH and ORP must be measured

and controlled simultaneously, e.g.

electroplating or swimming pool applications.

Under this setup, pH is always maintained and

controlled as a first priority. Only when pH

readings are within set limits, will the ORP

controller be allowed to operate the pumps.

pH calibration is quick and easy with push-

buttons. Calibration buffer sets include US, NIST

and DIN standards. Electrode condition is

updated and displayed after each calibration.

For applications where Hydrofluoric (HF) acid is

present, either Antimony or HF-resistant glass

electrodes must be used.

When Antimony electrodes are used, select

‘Antimony’ electrode option from controller menu,

to download relevant Antimony electrode data.
