Hanna Instruments, Inc products

The HI 2216 is a pH, ORP, ISE meter with five point pH calibration and 0.001 pH resolution.

HI 2210 is a benchtop pH and °C meter. This meter also features a reading stability indicator used during calibration and a measurement memory/memory recall function.

The HI 2213 is a pH and temperature benchtop meter. HI 2213 can also measure oxidation reduction potential (ORP) in the mV range. A relative mV feature is provided.

HI 2211 is a benchtop pH/ORP and °C meter. HI 2211 adds measurement for ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the mV range.

A properly manufactured and maintained pH electrode will retain its measuring integrity for a long time. As a result of many factors such as age, poor maintenance or improper handling, any electrode in time will lose its integrity.

With features such as a built-in beaker holder, beaker-top electrode holder and rugged, 2-in-1 pH and temperature sensor, the HI 207 is designed to meet busy classroom environments.
