  • Page 4: General Description

    General Description 3. GENERAL DESCRIPTION The Hanna Instruments HI2210 HI2211 are microprocessor based pH and temperature bench meters. HI2211 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...
  • Page 5 Operational Guide 5.2. Electrode And Probe Connections For pH or ORP combination electrode connect to the BNC connector on the back of the instrument. For electrodes with a separate reference connect the electrode’s BNC to the BNC connector and the reference electrode plug to the reference socket.

  • Page 6: Ph Calibration

    pH Calibration 5.5. ORP Measurements (HI2211 only) 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. The surface of the ORP electrode must be clean and smooth in order to obtain an accurate measurement.
  • Page 7 pH Calibration 6.2. Procedure A two‑point calibration is recommended however a one‑point calibration will be permitted. Calibration can be performed using the five memorized buffers: pH 4.01, 6.86, 7.01, 9.18 and 10.01. 6.3. Two-Point Calibration • Submerse the pH electrode and the temperature probe approximately 3 cm (1 1/4") into a buffer solution and stir gently.

  • Page 8: Temperature Calibration

    7. TEMPERATURE CALIBRATION Note: for technical personnel only. All the instruments are factory calibrated for temperature. Hanna Instruments’ temperature probes are interchangeable and no temperature calibration is needed when they are replaced. If the temperature measurements are inaccurate, temperature recalibration should be performed.

  • Page 9: Ph Buffer Temperature Dependence

    pH Buffer Temperature Dependence 8. pH BUFFER TEMPERATURE DEPENDENCE The temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions. During calibration the instrument will automatically calibrate to the pH value corresponding to the measured or set temperature.
