  overview

  P700IQPhosphate analyzer can be directly installed in outdoor process tanks on site/Pool side operation and short distance sample pretreatment pipeline ensure real-time measurement values. The device has good double-layer protection and active temperature control (optional), and is not affected by external climate.

  The automatic calibration function with selectable calibration intervals provides special operational safety (which can also be turned off).

  The measurement principle is based on the long-standing use of phosphomolybdate yellow spectrophotometry to measure orthophosphate. Additionally,P700IQThe use of medication is particularly minimal, greatly reducing operating costs.

  The measurement range is large,P700IQWidely applicable, the measurement range can be switched at any time without any cost.

  P700IQMembranes

• Integrated design (permeation pump can be integrated into)P700IQInside the casing

• Easy and fast cleaning

• Long operation time between secondary cleaning

• High operational safety

  Sample pretreatment is specifically designed forP700IQDesigned for very low sample sizes, the permeate is supplied to the analyzer through a vacuum pump. The filter membrane is installed on the edge of the pool through a bracket and immersed in the pool, and maintenance is carried out directly at the edge of the pool:Users can lift the filter membrane from the pool without any effort and clean it, saving time and making maintenance simple.

  Working principle

  P 700 IQPhosphate analyzer measures the concentration of phosphate in aqueous solutionIt was measured using the phosphomolybdate yellow spectrophotometric method.

  The reagent contains ammonium metaaluminateNH₄VO₃Ammonium molybdate（NH₄）₆MO₇O₂₄And sulfuric acidH₂SO₄In acidic solution, phosphate reacts with reagents to form a pale yellow phosphomolybdate complex. use420nmMeasure the absorbance of the wavelength measurement solution and calculate the concentration of orthophosphate.
