pH MEASUREMENTS OPERATIONAL GUIDE INITIAL PREPARATION TOP VIEW °C BNC electrode connector OFF mV TOP VIEW OF HI 8915 pH Turn the rotary knob to the pH position to display the pH measurement. Shake the electrode briefly and allow a couple of minutes for the electrode to adjust and stabilize. The display will show the pH value compensated for the manually adjusted temperature. Turn the instrument ON, shake the electrode briefly and wait until the stability indicator "∆" stops blinking.
Notes: • In order to take accurate pH measurements, make sure that the instrument is calibrated for pH before use. • For a faster response time when using refillable electrodes, unscrew the refill hole cap. Dip the temperature probe or the pH/°C electrode into the sample and allow the reading to stabilize (a couple of minutes). For HI 931000, to display the measured temperature, press and hold the °C key. When the °C key is released, the display will return to the pH reading.
• Set the rotary knob to °C position to display the manual temperature setting and adjust the °C trimmer until the LCD shows the measured temperature. pH CALIBRATION For best accuracy, frequent calibration of the instrument is recommended. The instrument should be recalibrated for pH: a) Whenever the pH electrode or temperature probe is replaced. b) At least once a month. c) After testing aggressive chemicals. d) Whenever the battery has been replaced. e) When high accuracy is required.
• Stir gently and wait a couple of minutes for thermal equilibrium. Note: The electrode should be submerged approximately 4 cm (1½") into the solution. The temperature probe should be located as close as possible to the pH electrode. • Press °C to display the temperature of the buffer (e.g. 20.0°C). PROCEDURE FOR HI 931000 • Turn the meter on. Note: The "∆" indicator blinks when the reading is not stable. • Press CAL and the display will flash "7.01 ∆".

ELECTRODE CONDITIONING AND MAINTENANCE If the bulb and/or junction are dry, soak the electrode in HI 70300 Storage Solution for at least one hour. For refillable electrodes: If the refill 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. TEST MEASUREMENT Rinse the electrode tip with distilled water.
Inorganic Soak in Hanna HI 7074 Inorganic Cleaning Solution for 15 minutes. Oil /grease Rinse with Hanna HI 7077 Oil and Fat Cleaning Solution. IMPORTANT: After performing any of the above cleaning procedures rinse the electrode thoroughly with distilled water, drain and refill the reference chamber with fresh electrolyte (not necessary for gel-filled electrodes), and soak the electrode in HI70300 Storage Solution for at least 1 hour before taking any measurement.
