High quality trace sodium electrode can achieve a monitoring lower limit of 0.0 lppb;

The measuring electrode, reference electrode, and temperature sensor are placed in three measuring chambers respectively, minimizing interference to the reference system to the greatest extent possible;

The instrument alkalization adopts the principle of Wenqiu Li, using the pressure difference of the waterway to generate a constant suction force, automatically sucking in the gasified alkalizing agent and mixing it with the water sample, overcoming the unstable alkalization effect caused by the clogging and aging of the permeation method silicone tube;

◎ Automatic constant pressure and current: The waterway automatically compensates for changes in water sample flow rate and pressure.

Equipped with high-quality ppb level dedicated electrodes and a stable alkalization system, ensuring accurate measurement;

The consumables only include electrodes, reference filling solution, and alkalizing agent, with extremely low maintenance costs in the later stage;

The measuring electrode has good performance and the instrument module is simple and visible, which greatly reduces maintenance work;

◎ Blank verification: eliminate the background concentration generated by sodium ions in the alkalizing agent and other ions in the sample water;

◎ It is possible to measure the sodium content or standard solution of other water samples offline statically to check the performance of the instrument or electrode.
