    WARRANTY HI 2209 and HI 22091 are guaranteed for two years against defects in workmanship and materials when used for their intended purpose and maintained according to instructions. Electrodes and probes are guaranteed for six months.

  • Page 3: Preliminary Examination

    GENERAL DESCRIPTION HI 2209 bench 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.

    OPERATIONAL GUIDE POWER CONNECTION Plug the supplied 12 Vdc adapter into the power supply socket (#12 on page 4). Note: Make sure the mains line is protected by a fuse. ELECTRODE CONNECTION For combination pH or ORP electrodes (with internal reference) connect the electrode's BNC to the socket provided (#10 on page 4).
  • Page 7 For the rinsing process, it is recommended to use a liberal amount of the next solution to be measured. TAKING ORP MEASUREMENTS HI 2209 and HI 22091 have the capability to take ORP measurements, using an ORP electrode. Hanna Instruments offers a variety of ORP electrodes for this purpose (see accessories).

  • Page 8: Ph Calibration

    pH CALIBRATION IMPORTANT The instrument's pH range should be re-calibrated: • When the meter is new. • Whenever the pH electrode is replaced. • At least once a month. • After use in aggressive chemicals. • After cleaning procedure and changing the reference electrolyte. •...
  • Page 9 • Rinse and immerse the pH electrode into pH 7.01 buffer and shake briefly. Wait for the reading to stabilize. • Note the temperature of the buffer solution using a ChecktempC or a glass thermometer (e.g. 20°C). • Press and hold the Temp key to select temperature setting.

  • Page 10: Ph Buffer Temperature Dependence

    pH BUFFER TEMPERATURE DEPENDENCE Temperature has an effect on pH. The calibration buffer solutions are affected by temperature changes to a lesser degree than normal solutions. For manual temperature calibration please refer to the following chart. º F º For instance, if the buffer temperature is 25°C, the display should show pH 4.01, 7.01 or 10.01 at pH 4, 7 or 10 buffers, respectively.

  • Page 11: Electrode Conditioning And Maintenance

    ELECTRODE CONDITIONING AND MAINTENANCE Note: To prevent damage to the electrode, remove the pH electrode from the solution before turning the meter off. If the meter is OFF, detach the electrode from the meter before immersing the electrode in the storage solution. Reference Filling Hole Reference...

For a faster response, unscrew the fill hole screw during measurements. For AmpHel ®...
  • Page 13 CLEANING PROCEDURE General Soak in HI 7061 general cleaning solution for approximately 30 minutes. Removal of films, dirt or deposits on the membrane/junction: - Protein Soak in HI 7073 protein cleaning solution for 15 min. - Inorganic Soak in HI 7074 inorganic cleaning solution for 15 minutes.

  • Page 14: Temperature Correlation For Ph Sensitive Glass

    TEMPERATURE CORRELATION FOR pH SENSITIVE GLASS The resistance of glass electrodes partially depends on the temperature. The lower the temperature, the higher the resistance. It takes longer time for the reading to stabilize if the resistance is higher. In addition, the response time will suffer to a greater degree at temperatures below 10°C.
