This manual describes the operation of Hanna HI 83216 multiparameter bench photometer, including the instrument composition, pre-examination, operation, instrument maintenance and other contents.
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 use optional compatible software for managing results.
The manual covers the significance of pool and spa testing, including the importance of monitoring disinfection residuals, pH, calcium hardness, and alkalinity to prevent corrosion or scaling. It details the Langelier Index formula for calculating water balance and provides reference tables for temperature, hardness, and alkalinity factors. Operational guides for measuring parameters such as Alkalinity, Calcium Hardness, Free Chlorine, Total Chlorine, and Cyanuric Acid are included, along with health and safety warnings.

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.
It is recommended to maintain the alkalinity value within the range from 80 to 125 ppm as calcium carbonate.
Theoretically, a LI of zero indicates perfect water condition for swimming pools.
