The HI96725 Chlorine, Cyanuric Acid, and pH Portable Photometer combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine these three common water quality parameters using ready made reagents. The HI96725 offers many advanced features including the exclusive CAL Check™ function used for performance verification and calibration of the meter.

The HI96725 portable photometer is for the measurement of free and total chlorine, cyanuric acid, and pH. 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.
