    2 Using the Pyxis SP-710B 2.1 Battery Installation The main module of the SP-710B is powered by four AA alkaline batteries. Typical battery life is 10,000 measurements, or 10 months. When the battery capacity is critically low, the SP-710B displays a LOW BATTERY warning for five seconds, and then automatically turns off.

    SP-710B had been equilibrated (stored). The values will be displayed in white with a blue background if a stable value is reached (Figure 3). For a sample with conductivity in the range of 100 to 6000 S/cm, the measured value should be stabilized in the range of 98–102 to 5940–6060 S/cm, respectively.

    Ag/AgCl reference electrode. Potassium chloride (KCl) electrolyte filling gel is sealed in the Ag/AgCl electrode. The amount of reference electrolyte in the SP-710B is significantly larger than that used in a common laboratory pH electrode. This reduces the chance of the filling solution being diluted or contaminated and increases the electrode life.

  • Page 14: Orp Measurement Principle

    If the ORP value of the standard is referenced to the standard hydrogen electrode (SHE), the ORP value reported by the SP-710B is SHE-based, i.e., in the unit of Eh. If the ORP value of the standard is referenced to the Ag/AgCl (3M KCl) electrode, the ORP value reported by the SP-710B is referenced to the same, commonly noted as (Ag/AgCl, 3M KCl).

    Note: In an emergency, “non-PTSA” water, such as city water, can be used. 2. Power the SP-710B on by pressing the OK key. Allow 5-10 seconds for meter to stabilize. 3. A screen like Figure 11 appears. The unit is actively reading and displaying both PTSA and Conductivity.
  • Page 16 Cond (conductivity) calibration. Press OK to start the calibration procedure. The default conductivity calibration screen is the Combined Calibration (Figure 16). This will calibrate both Conductivity (at 1000 µS) and PTSA (at 100 ppb) when using the Pyxis PTSA- 1010C combined standard.

    3. Press Calib (the > key) to launch the calibration selection screen (Figure 12). Press Calib again to select Cond (conductivity) calibration. Press OK to start the calibration procedure. A screen like Figure 16 appears. This is the default combined Calibration mode, which requires the Pyxis combined standard.

  • Page 19: Ph And Orp Calibrations

    Figure Figure 5 pH and ORP Calibrations The commonly used pH 4.00, 7.00, and 10.00 buffer standards can be used to calibrate the SP-710B pH measurement. Unlike the pH calibration, ORP calibration procedure and the calibration standards are not standardized by the industry or government institutions. We recommend that you use Zobell’s ORP standards (or Pyxis ORP-220) to calibrate the SP-710B and pay attention to the reference electrode on which the ORP value is referenced.

  • Page 20: One-Point Calibration

    When the one-point pH 7 calibration is complete, press Exit to exit, or continue to the pH 4 or pH 10 calibration. If a second buffer is added into the cell, the SP-710B automatically determines the buffer pH and displays the determined buffer pH value for confirmation.

  • Page 21: Orp Calibration

    Press + or – to select an ORP value to match your ORP standard. Press Calib to complete the calibration. Figure 29 The ORP scale of the SP-710B depends on the ORP scale of the calibration standard. For example, if the value of 220 mV for the common Zobell’s standard at 25 C is entered in the above calibration, the ORP value reported by the SP-710B after calibration is referenced to the Ag/AgCl(3M KCl) scale.
