Perform routine water quality parameter measurements in your wastewater and drinking water applications with high accuracy and stability using the Thermo Scientific™ Orion™ Chlorine XP Water Quality Analyzer. With minimal maintenance, low cost of ownership, and multiple parameter measurement in one unit, our chlorine analyzer provides one of the most comprehensive water quality monitoring solutions on the market.

The Orion Chlorine XP Analyzer measures free, total, and combined chlorine as well as pH and temperature, providing accurate, objective, and instantaneous readings of chlorine in water. The colorimetric technology and auto calibration functionality minimizes the need for periodic calibrations and is compatible with all disinfectant systems. User-selectable reagent mixing allows users to increase usage per set, providing up to 60 days of unattended operation.
