GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

The Hanna HI 2210 and HI 2211 are microprocessor-based pH and temperature bench meters.

HI 2211 can also be used for ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the mV range.

pH measurements are compensated for temperature effect manually or automatically with the HI 7662 temperature probe.

The instrument is equipped with a large easy-to-read LCD which shows the pH (or mV) and temperature simultaneously, together with graphic symbols.

The calibration process is guided step by step through clear indications on the LCD. A stability indicator makes the calibration procedure error-free.

Hanna Instruments reserves the right to modify the design,

construction and appearance of its products without advance notice.

• The pH is displayed on the primary LCD and the temperature on the secondary LCD.

• If the pH reading is out of range, “----” will be displayed on the LCD.

If measurements are taken successively in different samples, it is recommended to rinse the electrode thoroughly with deionized water or tap water and then with some of the next sample in order to prevent cross-contamination.

The pH reading is affected by temperature. In order to measure the pH accurately, the temperature effect must be compensated for. To use the Automatic Temperature Compensation feature, connect and submerge the HI 7662 temperature probe into the sample as close as possible to the electrode and wait for a few seconds.

If the temperature of the sample is known, manual temperature compensation can be performed by disconnecting the temperature probe.

The display will then show the default temperature of 25 °C or the last recorded temperature reading

with the “°C” tag blinking. The temperature can now be adjusted with the ARROW keys (from -9.9 °C to

120.0 °C).

An optional ORP electrode must be used to perform ORP measurements (see Accessories).

Oxidation-reduction potential (REDOX) measurements provide the quantification of the oxidizing or reducing power of the tested sample.

To correctly perform a redox measurement, the surface of the ORP electrode must be clean and smooth.

• Press RANGE to enter mV range.

• Submerge the tip of the ORP electrode 4 cm (1½") into the sample to be tested and allow a few seconds for the reading to stabilize.

• The instrument displays the mV reading on the primary LCD and the temperature on the secondary LCD.

• If the reading is out of range, “----” will be displayed on the LCD.
