OPERATIONAL GUIDE • Press the pH key to display the pH measurement. Power connection Plug the supplied 12 Vdc adapter into the power supply socket (#9 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).
• Note the temperature of the buffer solution using a ChecktempC or a glass thermometer (e.g.20°C). 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. • For greatest accuracy. • Press the °C key to select temperature setting.
pH VALUES AT VARIOUS TEMPERATURES ELECTRODE CONDITIONING AND MAINTENANCE 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. Note: to prevent damage to the electrode, remove the pH electrode from the solution before turning the meter off.
For refillable electrodes: If the filling solution (electrolyte) is more than 2½ cm (1") below the fill hole, add HI 7082 3.5M KCl electrolyte solution for double junction or HI 7071 3.5M KCl+AgCl electrolyte solution for single junction electrodes. For a faster response, unscrew the fill hole screw during measurements. For AmpHel® electrodes: If the electrode does not respond to pH changes, the battery is run down and the electrode should be replaced.
TEMPERATURE-RESISTANCE CORRELATION FOR HANNA 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.
