This is an instruction manual that introduces the use of HANNA HI 83216 Multiparameter Bench Photometer.
The HI 83216 is a multiparameter bench photometer dedicated for pool and spa applications. It measures six different methods using specific liquid or powder reagents and features a powerful interactive user support system with a tutorial mode. The instrument can be connected to a PC via a USB cable to manage results using optional compatible software.
The manual covers preliminary examination, abbreviations, general descriptions, and the significance of pool and spa testing parameters such as disinfection residuals, pH, calcium hardness, and alkalinity. It includes detailed sections on the principle of operation, functional descriptions, tips for accurate measurement, health and safety, and operational guides for various tests including alkalinity, calcium hardness, free chlorine, total chlorine, and cyanuric acid.

Most pool managers prefer to keep the pH between 7.2 and 7.4 to ensure low corrosion rates and sufficient chlorine activity.
It is recommended to maintain the calcium hardness value within the range from 200 to 400 ppm as calcium carbonate.
