The HI96710 pH, Free Chlorine, and Total Chlorine Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the pH, free chlorine, and total chlorine concentration of water samples using ready made reagents. The HI96710 offers many advanced features including the exclusive CAL Check^™ function used for performance verification and calibration of the meter.

The HI96710 portable photometer is for the measurement of pH, free chlorine, and total chlorine. Hanna's portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check^™ feature utilizes ready-made, NIST traceable standards to verify both meter validation and calibration. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.
