This document is the instruction manual for Hanna Instruments' pH/mV/°C Bench Meters with Custom Buffers HI 2212 HI 2213
The Hanna Instruments HI 2212 and HI 2213 are microprocessor-based bench meters designed for pH and temperature measurements. The HI 2213 model additionally supports Oxidation Reduction Potential (ORP) and relative mV measurements. These instruments feature a liquid crystal display (LCD) and allow for calibration using standard or custom buffers.
| Measurement Type | pH, Temperature, ORP (HI 2213) |
|---|---|
| Calibration Points | Up to three-points |
| Warranty Period | Two years |
| Electrode Warranty | Six months |
| Power Supply | 12 VDC |
The instrument should be recalibrated at least once a week, whenever the pH electrode is replaced, or after testing aggressive chemicals.
The HI 2212 and HI 2213 meters are guaranteed for two years against defects in workmanship and materials.
Yes, the HI 2213 can also measure Oxidation Reduction Potential (ORP) in the mV range.
