3051 Hardness Analyzer

Range: 0-1ppm

Range: 0-250ppb


The Waltron 3051 Calcium Hardness Analyzer is the industry’s only online instrument able to deliver accurate and repeatable results for online analysis and control of extreme low-level Calcium hardness in clean water applications. The 3051 uses Waltron’s proprietary colorimetric chemistry to achieve the most accurate results (+/- 5ppb at the lowest levels) in applications where hardness must be strictly managed. An enhanced color touchscreen user interface makes the 3051 easy to operate and configure, and the clever fast-loop reservoir feature allows accurate measurement independent of flow. The 3051 automates manual bench test analysis for accurate and reliable results, greatly enhanced visibility on changes in hardness concentrations, and earlier detection of potential problems.
