HACH EZ1008 Colour Analyser
Product #: EZ1008.XXXXXXXX | Contact Hach
Online analysis of Colour (Platinum-Cobalt Scale) in water
The EZ1000 Colour Analysers achieve excellent precision and accuracy. At the heart of the colorimeter is a compact photometer assembly developed especially for the EZ Series. Consumption of reagents is reduced by low volume analysis, yet high sensitivity is assured by a long optical path length. The limit of detection is in the low µg/L range.
Results you can rely on
Smart automatic features for calibration, validation, priming, and cleaning are embedded in the controller software and contribute to analytical performance, maximised uptime, and negligible operator intervention. Precision micropumps dose all reagents. Sample lines and analysis vessel are cleaned with demineralised water to eliminate cross-contamination between samples. The electronic and wet-chemical parts of the analyser are strictly separated. A transparent door allows for instant visual inspection of the wet part.
Flexibility that meets your needs
EZ Series Colour Analysers come in an attractive, ergonomic mainframe with a compact footprint. All hardware is controlled by the integrated industrial panel PC. The modular build allows the analyser to match your application and operational needs.
- The standard measuring range can be narrowed by a different calibration range or extended via internal dilution options.
- Analogue and digital output options
- Multiple stream analysis for up to 8 sample streams
