The Mettler Toledo Thornton 2300Na Sodium Analyzer is an on-line process analytics instrument for sodium measurement in high-purity water applications.
It is designed to support trace sodium monitoring where early detection of contamination is important to water treatment, microelectronics pure/ultrapure water, and power cycle chemistry applications.
As part of the Mettler Toledo sodium analyzer line, the 2300Na provides automated sodium measurement with calibration support, adjusted pH monitoring, temperature display, and analyzer status visibility in a single unit.

Its configuration supports continuous plant use with options suited for clean sample rooms or more demanding plant-floor environments.
