The HI 222 pH/mV/ºC Bench Meter is a meter with pH, mV, and temperature measurement functions, and can be used for calibration checks and parameter settings. The meter is covered by a two-year warranty, while the electrodes and probes are covered by a six-month warranty.
The HANNA Instruments HI 222 is a microprocessor-based bench meter designed for measuring pH, ORP (mV), and temperature. It features a Calibration Check function that performs diagnostic tests to detect electrode problems affecting accuracy. The device includes enhanced calibration messages, displays electrode condition and response time on the LCD, and supports logging up to 100 samples.
| pH Range | -2.00 to 16.00 pH |
|---|---|
| mV/ORP Range | -999.9 mV / +2000 mV |
| Temperature Range | -20.0 to 120.0 °C |
| Temperature Compensation | Automatic or manual, from -20 to 120°C |
| Logging Capacity | 100 points |
For best results and constant display of electrode condition, we suggest at least a daily calibration.
The closest full-scale value will be displayed blinking on the primary LCD.
