HI97747 is an advanced portable photometer for the measurement of copper 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.
Due to its malleability, thermal and electrical conductivity, and corrosion resistance, copper is used in a variety of industrial and technological applications. Copper may also be present in natural water and effluents due to widespread use to control biological growths in reservoirs and distribution pipes.
The HI97747 uses the bicinchoninate method to measure copper in water with concentrations of up to 1.500 mg/L (ppm). When the reagent is added to samples containing copper, the sample will turn a purple hue; the greater the concentration, the deeper the color. The associated color change is then 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 lower levels of copper, a narrow band interference filter at 575 nm allows only green-yellow 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, while transmittance decreases.
This innovative optical system offers superior performance in accuracy, repeatability, and required time to perform a measurement. This compact, waterproof meter has a tutorial mode that walks the user graphically, step by step, to perform a measurement. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use.
CAL Check
Advanced features including CAL-Check to verify performance and if necessary, recalibrate.
Setup Options
Backlit dot matrix LCD that offers an exceptionally intuitive user interface that is easy to read and understand.
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.
