HI 2210 and HI 2211 are microprocessor-based pH/mV/°C bench meters for water analysis.
The Hanna Instruments HI 2210 and HI 2211 are microprocessor-based bench meters designed for measuring pH, millivolts (mV), and temperature. The HI 2211 model additionally supports Oxidation-Reduction Potential (ORP) measurements in the mY range. Both instruments feature a large LCD display that shows readings simultaneously with graphic symbols and support manual or automatic temperature compensation.
| pH Range | -2.00 to 16.00 pH |
|---|---|
| mV/ORP Range (HI-2211 only) | +/-3999 mY / +2000 mY |
| Temperature Range | -9.9 to 120.0 °C |
| pH Resolution | 0.01 pH |
| pH Accuracy (at 20°C) | ±0.01 pH |
| Temperature Compensation | Manual or Automatic |
The instrument is supplied with a HI 1131B Glass-body Combination pH Electrode, HI 7662 Temperature Probe, HI 70404 Electrode Holder, buffer solutions, electrolyte solution, and a power adapter.
The instrument should be recalibrated whenever the electrode is replaced, at least once a week, or after testing aggressive chemicals.
Calibration has a choice of five memorized buffers: pH 4.01, 6.86, 7.01, 9.18, and 10.01.
