AQUALYZER® 9001 SERIES

Sodium Analyzer
Aqualyzer® 9031

The Waltron Aqualyzer® 9031 Sodium Analyzer is the most advanced online instrument specifically developed for use in continuous measurement and determination of sodium ion concentration.

Common Sodium Analyzer 9031 application points in a boiler system for online sodium measurement include:make-up water,condensate,boiler feedwater and saturated steam/main steam.

The Aqualyzer® 9031 sodium analyzer operates automatically and comes complete with true fully automatic calibration.

Aqualyzer® 9031 Sensor Unit
The sample flows through the heat exchanger, passes through constant head (used to stabilize minor changes in flow rate) and through the 3 solenoid valves. A vapor entrainment mechanism adds alkaline buffer vapor to the sample before it enters the sodium measuring flow cell and flows to drain. Calibration and grab sample are controlled automatically by the analyzer. Standard/grab sample liquid is brought into system via the three 3-way solenoid valves. A thermistor is housed in the flowcell and is used to detect the temperature of the sample/standard/grab sample.
