    • Diagnostic features to alert the user when the electrode needs cleaning. • User selectable “Outside Calibration Range” warning. • User-selectable “Calibration Time Out” to remind when a new calibra- tion is necessary. Hanna Instruments reserves the right to modify the design, construction and appearance of its products without advance notice.
  • Page 4 Moreover, they offer an extended temperature range from –20 to 120 ºC (–4 to 248 ºF), using HI 7662-T interchangeable temperature probes. These instruments can also measure with ORP electrodes, thanks to their capability to measure mV with a resolution up to 0.1 mV. HI 3221 and HI 3222 can also measure with ISE electrodes on ppm scale.
