9031CX Sodium Analyzer
Range: 0.1ppb – 10ppm
The Waltron 9031CX Sodium Analyzer combines simplified design with uncompromised performance for the control of sodium and damaging anions in ultrapure water applications. This economic manual calibration-only option can save your budget as well as mounting space, with options to panel mount the separated transmitter and wet section. An enhanced color touchscreen user interface makes the 9031CX easy to operate and configure, and a constant head allows accurate measurement, independent of flow. Common 9031CX application points in a boiler system for online sodium measurement include: make-up water, condensate, boiler feedwater, and saturated steam/main steam.
