HI97706 is an advanced portable photometer for the measurement of phosphorus in water. This meter offers a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
Phosphorus is an essential element for plant and animal growth commonly found in natural water systems, such as lakes, oceans, and soil. However, large concentrations of Phosphorus cause excessive microorganism and algae growth and corrosive to piping in high concentrations.
The HI97706 uses an adaptation of the Standard Method for the Examination of Water and Wastewater, 23rd edition, amino acid method to measure phosphorus concentrations of up to 15.0 mg/L (ppm). When the reagent is added to samples containing Phosphorus, the sample turns a blue hue; the greater the concentration of phosphorus, the deeper the color. The associated change is colorimetrically analyzed according to the Beer-Lambert Law which states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For Phosphorus determination, a narrow band interference filter at 525 nm allows only green light to be emitted and passed through the sample cuvette. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, and transmittance decreases.
CAL Check
Advanced features including CAL-Check to verify performance and if necessary, recalibrate.
Multiple Chemical Forms
Results can be displayed in multiple chemical forms.
Setup Options
Setup options for meter personalization include date and time format, language, and enabling the tutorial mode.
Tutorial Mode
Tutorial mode for step-by-step instructions to guide a first-time user in how to perform a measurement correctly.
Reaction Timer

Stable Light Source:
High Efficiency Light Source:
High Quality Filters:
Greater Light Yield:
A focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes.
CAL Check Functionality:
Large Cuvette Size:
Intuitive Dot Matrix Display:
Auto-off Protection:
