Measures high-range hardness using EPA-approved calmagite chemistry

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.

Accuray and continuously measures up to two sample streams

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

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.

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.

Makes your water softening system more efficient and less costly

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