  • Page 7: Initial Preparation

    INITIAL PREPARATION Each meter is supplied complete with a 9V battery. Slide off the battery compartment cover on the back of the meter, install the battery while paying attention to its polarity. Always remove the electrode protective cap before taking any measurements.
  • Page 8 After cleaning, rinse the electrode with some of the sample to be measured. Temperature compensation The pH reading is directly affected by temperature. In order for the meter to measure the pH accurately temprature must be taken into consideration. HI8014 provides only for manual compensation.

  • Page 9: Orp Measurements

    ORP MEASUREMENTS Connect an ORP electrode to the BNC socket on the top of the meter. To enter the “mV” mode (ORP Oxidation Reduction Potential) switch the rotary knob to the mV position. To measure the mV of a sample submerge the ORP electrode tip (4 cm/1½”) in the sample to be tested.
  • Page 10 (HI7004) if you are going to measure acidic samples, or pH 7.01 (HI7007) and pH 10.01 (HI7010) for alkaline measurements. If you need to calibrate HI8014 to NBS standards, use pH 6.86 (HI7006) instead of pH 7.01 and pH 9.18 (HI7009) instead of pH 10.01.
  • Page 11 Note: The electrode should be submerged approximately 4 cm (1½”) into the solution. The HI98501 should be located as close as possible to the pH electrode. • 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.
  • Page 12 4.01 or 7.01 or 10.01. With the temperature at 20 °C, the display should show pH 4.00 or 7.03 or 10.06. Likewise, at 50 °C, the display should show pH 4.06 or 6.98 or 9.82. HI8014 has the capability to take ORP measurements, if using an optional ORP electrode.
  • Page 13 pH, mV and °C readings can be transmitted through the output sockets at a voltage that proportionally matches the displayed value. For example, when the meter reads 2.00, 7.00 or 12.00 pH, it emits a 200, 700 or 1200 mV signal, respectively. This makes it unnecessary to use conversion tables and charts.
  • Page 14 * Only available with refillable electrodes. PREPARATION Remove the protective cap. DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with electrodes and they will disappear when rinsed with water. During transport tiny bubbles of air may have formed inside the glass bulb.

  • Page 15: Test Measurement

    If the bulb and/or junction are dry, soak the electrode in HI70300 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 HI7082 (3.5M KCl Electrolyte Solution) for double junction or HI7071 (3.5M KCl+AgCl Electrolyte Solution)

  • Page 16: Cleaning Procedure

    CLEANING PROCEDURE General Soak in Hanna HI7061 General Cleaning Solution for approximately 30 minutes. Removal of films, dirt or deposits on the membrane/junction: Protein Soak in Hanna HI7073 Protein Cleaning Solution for 15 minutes. Inorganic Soak in Hanna HI 7074 Inorganic Cleaning Solution for 15 minutes.
  • Page 17 • Slow Response/Excessive Drift: Soak the tip in Hanna Solution HI7061 for 30 minutes, rinse thoroughly in distilled water and then follow the Cleaning Procedure (see page 16). • For ORP Electrodes: polish the metal tip with a lightly abrasive paper (paying attention not to scratch the surface) and wash thoroughly with water.
  • Page 18 This meter is powered by a 9V battery that is located on the rear of the instrument. When the battery becomes weak, the meters provide the following: reaching a certain minimum threshold, automatically switches the LCD off. Since a low voltage may also result in loss of calibration data or unreliable measurements, it is recommended to replace the battery immediately.
