The Phosphax sc online analyzer provides reliable and accurate PO4 measurements
Multiple measurement ranges for a variety of wastewater applications
With detection limits as low as 0.05 mg/L and as high as 50 mg/L, the Phosphax sc phosphate analyzer can be used anywhere in the wastewater treatment process, from
the influent or start of the phosphorus removal process where phosphate levels may be high to the effluent where phosphate levels are at their lowest.
Low cost of operation with proven yellow method
The Phosphax sc analyzer determines ortho-phosphate concentration using the molybdovanadate yellow colorimetric method which optimizes reagent consumption and helps save on operating costs.
Generate actionable insights from measurement data
The Phosphax sc is Claros enabled so you can leverage the Hach Water Intelligence System to collect, manage and analyse data from your instrument.
Easy installation at the measurement point
Hach’s Phosphax sc phosphate analyzer is designed to be installed at the measurement point (indoor and outdoor options). The housing is weatherproof and lockable for
installation at the basin, even in the toughest climates. Mounting options include: wall, rail, or standing. The unit comes complete and assembled; no separate housing is
required.
Low maintenance
Several features make the Phosphax sc phosphate analyzer easy to use and maintain:
1. Automatic cleaning at customized intervals.
2. Automatic zero-calibration at each measuring cycle.
3. Prognosys Predictive Diagnostics alerts you to upcoming instrument issues and guides you on whether the changes in your measurements are due to your instrument or your water.
4. Easy access to reagents and wear parts.
