The 122pH is an online panel-mounted pH indicator with isolated 4-20mA transmitter output by Countronics. Large 0.8″ red LED display, auto temperature compensation via PT100, and 4-20mA output for SCADA, PLC, or remote display connection.
The isolated 4-20mA output transmits pH proportionally (4mA = pH 0, 20mA = pH 14) to PLCs, SCADA, data loggers, or remote displays. Isolation prevents ground loops common in industrial environments.
121pH is display-only — no output signal. 122pH adds an isolated 4-20mA transmitter output. Both have identical display and calibration features. Choose 122pH when SCADA integration or remote monitoring is needed.
122pH monitors and transmits 4-20mA — no relays. 112pH controls pH with two relay outputs for dosing pumps, plus 4-20mA. Choose 122pH for monitoring only; 112pH for automatic pH control.
Yes. The isolated 4-20mA output connects directly to any PLC analog input, SCADA, DCS, or data recorder. Isolation prevents ground loops in industrial environments.
Used in water treatment, STP, ETP, pharmaceutical, food processing, and chemical plants where pH must be monitored and transmitted to a central control system via 4-20mA signal.
