Waltron 9035 Sodium Analyzer

9035 Sodium Analyzer

Range: 0.1ppb – 10ppm

Waltron’s 9035 Sodium Analyzer delivers exceptional results in a streamlined package. An enhanced color touch screen user interface makes the 9035 easy to operate and easy to maintain. The 9035 Sodium Analyzer can be used in a variety of ultrapure water applications. Common measuring points in a boiler system for online sodium measurement include: make-up water, condensate, boiler feedwater and saturated steam/main steam. The Waltron 9035 Sodium Analyzer comes with true fully automatic calibration and offers many benefits in terms of ease-of-use and increased functionality.
