The pH 209 bench-top pH meter is designed for simplicity of use. It features a large easy-to-read liquid crystal display (LCD) and user friendly keyboard. The pH calibration is made simple through the easy-to-operate front panel knobs for offset and slope adjustment. A front knob is provided for easy manual temperature compensation of the pH reading. pH 209 can also measure ion concentration (ISE) and ORP (Oxidation Reduction Potential) in the mV range. The range selection (pH, mV or °C for temperature compensation) is made simple through the front membrane keyboard. The large LCD is provided with arrows that quickly and clearly indicate the selected range. It is also available the model pH209R with recorder output feature.
The Hanna Instruments pH 209 is a bench-top pH meter designed for simplicity of use, featuring a large liquid crystal display (LCD) and user-friendly keyboard. It allows for manual temperature compensation and can also measure ion concentration (ISE) and Oxidation Reduction Potential (ORP). A specific model, the pH 209R, includes an analog output feature.

The instrument's pH range should be re-calibrated when new, whenever the electrode is replaced, at least once a month, after use in aggressive chemicals, or for greatest accuracy.
If the bulb is dry, soak the electrode in HI 7030 storage solution for at least one hour.
