APA 6000 Ammonia and Monochloramine Analyzer


APA 6000 Ammonia and Monochloramine Analyzer
Product #: 5500610


Total Chloramination Control

Monitors all three critical Chloramination parameters: free ammonia, total ammonia and monochloramine

Selectable readout

The APA 6000 offers a variety of display options, including a display of all three Chloramination values simultaneously. Simple menu displays - in English, French, Spanish or German - guide you step by step through all procedures

Automatic functions

Self cleaning, self-calibrating and self-priming - simplify daily operation


The APA 6000 is enclosed in a NEMA 4X (IP66) shockproof and corrosion-resistant ABS case that protects components and helps maintain constant temperatures in the mixing chamber regardless of external temperature.

What's in the box?

Hach APA6000 Analyzer, a one-month supply of reagents, Tool kit, Maintenance kit, Installation kit, Installation and Maintenance Manual, and parameter specific Manual. (The power cord is ordered separately.)
