Model NA-600

Sodium Analyzer

Compact online analyzer for the automatic measurement of Sodium

DUAL COMPARTMENT ENCLOSURE
To ensure complete separation between the electronics and the wet part. The reagent bottle is located in the wet part.

 

AUTOMATIC CALIBRATION
Automatic 1, 2 points calibration minimizes intervention ensuring the most accurate results are obtained. Free selectable calibration intervals. Results of the last ten calibration are stored in the internal datalogger.

 

REDUCED OPERATING COSTS
Low reagent consumption. The design with no moving parts reduces maintenance requirements and minimizes cost of ownership.

 

MEASUREMENT PRINCIPLE
The sodium measurement is based on the proven accuracy of the glass sodium electrode for the online potentiometry detection of low ppb traces of sodium. The sodium sensor develops a potential proportional to the log of the sodium concentration, after the pH of the sample is raised to 11 to eliminate pH and ammonium interferences. This is obtained using reagent vapor addition.

 

GRAB SAMPLE CAPABILITY
Enables unattended analysis of manually collected samples. Results of external samples are stored in the datalogger, including time and data information.

 

COLOR TOUCHSCREEN UER INTERFACE
The NA-600 analyzer is equipped with a graphic touchscreen interface showing measured values and status information. Easy access to menus and functions. Multiple languages. Integrated datalogger with USB download.
