ADI 201Y Series systems

Analyzers tailored to your requirements

Metrohm Process Analytics can engineer and supply virtually any “unit operation” for sample preconditioning and can provide a complete working solution for most industrial processes.

Projects range from one analyzer in combination with a simple sample panel to complete packages with shelters, piping, wiring, and interfacing.

Stainless steel: when hygiene matters

The stainless steel housing option for the 201Y series is available for all hygienic applications in the food and beverage industry.

The watertight design withstands stringent hygienic cleaning procedures without the fear of rust and corrosion. This option is also suitable for harsh chemical environments where corrosion is unavoidable.

Titrolyzer for fast and accurate analysis

The ADI 2016 is a (potentiometric) titration-based analyzer using high-precision burets and high-performance electrodes that guarantees accurate results.

This absolute analytical method offers high selectivity through the use of dedicated electrodes and titrants, with no calibration needed. The titration method is suitable for a variety of proven standardized methods covering a huge number of wet chemical applications.

Ion Analyzer with unique methodology

The specially developed Dynamic Standard Addition (DSA) method with multi-calibration slopes makes the ADI 2018 suitable for ultimate low or high measuring ranges with enhanced accuracy and stability. The unique DSA feature automatically validates the measurement and eliminates sample matrix effects and inaccuracies at the same time.

Automatic calibration intervals guarantee a working ion-selective electrode when within preset limits and will trigger an alarm if the electrode needs to be reconditioned or replaced.

Colorimeter with high-performance photometer

Your color laboratory method can be directly implemented in a simple way to perform analysis online with the ADI 2019.

Modern LED technology used in a high-performance compact photometer module ensures repeatable and accurate results with high sensitivity at low concentration levels. Sample temperature effects are eliminated by means of a thermostatic cuvette producing trustworthy results for process optimization.
