Electronic transmitter / controller for the continuous measurement of the pH value orRedox (ORP) in water.

Transmitter AMU pH-Redox

Measuring and control transmitter for panelinstallation in a Noryl resin enclosure,96 x 96 x 120 mm (DIN 43700).

Measuring range:0 to 14 pH respectively -500 to +1500 mV

Sensor connections for a pH or ORP sen-sor, reference electrode, Pt1000 tempera-ture and for a digital sample flow meter.

Galvanically separated sensor connections.Automatic temperature compensations

according to Nernst with or without correc-tion functions.

Values for pH buffer solutions and redoxcalibration solution programmable.

Big backlit LC display for measuring value,sample temperature, sample flow and op-erating status.

Easy user menus in English, German,French and Spanish. Simple programmingof all parameters by keypad.

Data logger for 1500 data records storedat a selectable interval. Serial interface in-cluded for data download to PC with Mi-crosoft HyperTerminal.

Overvoltage protection for in- and outputs.

Two current outputs (0/4 - 20 mA) for con-ductivity and temperature signals.

Potential-free alarm contact as summaryalarm indication for programmable alarmvalues and for instrument faults.

Two potential-free contacts programmable

as limit switch or PID-control.Input for potential-free contact to freeze

the measuring value or to interrupt controlin automated installations (hold function orremote-off).
