Hach 2100 Series Laboratory Turbidimeters are engineered to provide superior accuracy and sensitivity in any application. The 2100AN is equipped with a stable halogen-filled tungsten filament lamp to meet the reporting requirements of EPA Method 180.1. This model is ideal for testing higher ranges of turbidity up to 10, 000 NTU. Additional absorbance, transmittance, and color measurement modes make the 2100AN the most flexible of any Hach benchtop turbidimeter.

Ratio technology provides highly accurate results
Interchangeable color filters provide ultimate flexibility
Optional cell adapters for the 2100AN Turbidimeter allow measurement of smaller sample volumes
Built-in printer provides a record of calibration and measurement data
Air purge prevents condensation in the sample chamber of the 2100AN
