The 3‑9900.394 is a field‑installable Direct Conductivity/Resistivity Module that interfaces Signet 2819 -2823 / 2839-2842 electrodes straight into the 9900 SmartPro ® base unit, providing signal filtering, conditioning, and ±2% reading accuracy with auto temperature compensation.
It enables the 9900 to drive isolated 4 -20 mA / relay actions for RO/DI quality interlocks, regenerate triggers, rinse accept/reject, and effluent conductivity alarms — no extra transmitter needed, just slot it in and configure via the ¼‑DIN display.
