Based on air Segmented Flow Analysis techniques (also known as Continuous Flow Analysis), the SEAL AutoAnalyzer 3 fully automates repetitive and complex sample analysis steps, from start-up to shutdown. The SEAL AA3 HR chemistry analyzer can also perform solvent extraction, distillation, gas diffusion, on-line filtration and in-line UV digestion in a continuously flowing stream. SEAL AA3 HR chemistry analyzers are fully supported with a library of over 700 documented applications including USEPA, ISO and ASTM standard methods.


The Future-Proof AutoAnalyzer

The AutoAnalyzer Designed for Environmental Analysis

Why the AA3 AutoAnalyzer is the First Choice in Chemistry Analyzers


The Future-Proof AutoAnalyzer

The SEAL AA3 HR AutoAnalyzer is designed to reduce your costs and future proof your investment with the modular design integrating a sampler, pump,chemistry test module, photometer and windows based software. The modular design makes it easily upgradeable to a system that measures up to 8 different analytes simultaneously. Each software program can run 2 systems -so up to 16 analyses simultaneously. The SEAL AA3 HR AutoAnalyzer also accepts Multitest Manifolds designed to extend any size analyzer to a multiple chemistry system capable of dual range of tests. Multitest Manifolds eliminate the need to change manifolds and filters when changing tests, and also reduce your hardware costs.


The AutoAnalyzer Designed For Environmental Analysis

SEAL AA3 HR chemistry analyzers incorporate features exclusive to SEAL AutoAnalyzers, and designed specifically for environmental applications, making them ideal for analyzing nutrients in wastewater, seawater, soil, fertilizer and plant extracts.
