HANNA HI-2211-02 Benchtop pH/mV Meter with pH Electrode and Temperature Probe

The HI-2211 are economical benchtop meters for precise pH and temperature measurements. The HI-2211 model also measures oxidation-reduction potential (ORP) in millivolts. Both units feature a large LCD with graphic prompts for step-by-step two-point calibration, a stability indicator, and measurement recall. Manual or automatic temperature compensation (ATC) ensures accurate pH readings, and compatibility with the HI-7662 temperature probe simplifies setup and operation.
