Accurate and Continuous Monitoring of Soluble Hardness

Hach's patented* APA 6000 Low-Range Hardness Analyzer accuray and continuously measures up to two sample streams for low levels （50 µg/L to 10 mg/L） of soluble hardness. Using a precise colorimetric method, the instrument performs an analysis every four minutes. It delivers continuous, accurate, and dependable performance with minimal cost for operation and maintenance. * U.S. Patent 5849592

Optimize Softener Performance

The APA 6000 Low-Range Hardness Analyzer is designed specifically for reliable and continuous analysis at low concentrations. Use it to establish an automatic system for monitoring softener performance in industrial, ultrapure, and water treatment processes.

Industrial and Ultrapure Water Applications

The APA 6000 Hardness Analyzer can be used to monitor both influent and effluent in industrial applications and water treatment processes including demineralizer effluent, boiler feed-water, boiler water, and process water. It is also appropriate for monitoring hardness in ultrapure processes used by pharmaceutical, electronic chip, and cosmetics manufacturers.

Easy to Use

The interface of the APA 6000 Hardness Analyzer is menu-driven with on-screen prompting, self-test diagnostics, security provisions, and flexible data logging options. Simple menus （available in English, French, German or Spanish） guide the user through each step of operation.

Automatic 2-Stream Analysis

Two separate sample streams can be monitored with the APA 6000 Hardness Analyzer when used with additional sample sequencing kits.
