Aztec 600 aluminium, ammonia, color, iron,

manganese, phosphate

Single- and multi-stream colorimetric analyzers

Measurement made easy

Introduction

The Aztec 600 range are advanced colorimetric
analyzers used to measure the levels of iron and
aluminium in water treatment plants.

They are available in both single- and multi-stream
versions; the multi-stream version can sample up to
three independent streams sequentially. This
manual covers both versions of the analyzer.

This Operating Instruction provides installation,
operation and maintenance procedures for the
Aztec 6000 colorimetric analyzers.
