Most Hanna meters are warranted for a period of two years against defects in workmanship and materials when used for their intended purpose. Probes and electrodes typically carry a shorter warranty period (e.g., six months).
Calibration frequency depends on the accuracy required and the nature of the samples. It is generally recommended to calibrate daily or before a series of measurements for best results.
