    • Continuous – The meter will continuously measure and update the display. This read type is useful when performing an experiment that requires continuous measurements to be taken. Press the log/print/0 key to export the measurement to the data log, if the data log is enabled in the setup menu, and to a printer or computer, if a printer or computer is connected to the meter and enabled in the setup. Isopotential Value The slope of all electrodes changes with temperature, based on the Nerst equation. The slope curves at the different temperatures intersect at the isopotential point, which is the concentration at which the potential of the electrode does not vary with temperature. For glass pH electrodes, this value is 7.00. Linear Regression Information The default is off which uses the traditional, segmented approach. The segmented approach is the most accurate and precise. More information can be found in the appendix section of this reference guide under the Multipoint Calibration Curve Feature. Selecting “on” for this option results in the use of a single best fit line for the calibration curve, and can be beneficial if pH measurements vary greatly.

  • Page 14: Orp Calibration

    ORP Calibration The mV reading of an ORP standard is dependent on the ORP electrode reference system, reference material, filling solution and ORP standard temperature. An ORP electrode can be automatically calibrated to read 420 mV relative to the Standard Hydrogen Electrode (E ) at 25 °C when the Orion ORP standard (cat. no. 967901 or 96791), Orion ORP electrode (cat. no. 9678BNWP, 9778BNWP, 9180BNMD or 9179BNMD) and Orion 4M KCl filling solution (cat. no. 900011) or 4M KCl gel (in electrode with cat. no. 9179BNMD) are used. The raw mV reading of an electrode with the same conditions is 220 mV at 25 °C. One standard can be used for ORP calibration. Always use fresh standard. Prepare the electrode according to the instructions in the electrode user guide. 1. Press f1 (Cal) to enter calibration mode. 2. Follow the screen prompts for calibration. 3.

    Testing a pH Electrode for Automatic Buffer Recognition To verify that the raw mV reading of the pH electrode in use is ± 30 mV from the theoretical mV reading of the buffer, and therefore verify that the pH electrode in use is capable of performing automatic buffer recognition, perform the following procedure. 1. Set the measurement mode to mV. Prepare the pH electrode according to the instructions in the pH electrode user guide. 2. Rinse the pH electrode with distilled water, blot it dry with a lint-free tissue and place the pH electrode into a pH 4.01 buffer at approximately 25 °C. 3. Wait for the measurement to stabilize and record the mV value of the pH 4.01 buffer when the meter indicates that the measurement is stable. The read type selected in the setup menu will determine how the mV measurements are displayed by the meter. 4. Remove the pH electrode from the pH 4.01 buffer. 5. Rinse the pH electrode with distilled water, blot it dry with a lint-free tissue and place the pH electrode into a pH 7.00 buffer at approximately 25 °C. 6. Wait for the measurement to stabilize and record the mV value of the pH 7.00 buffer when the meter indicates that the measurement is stable. 7. The mV reading of the pH electrode in pH 4.01 buffer should be in the range of +207 to +147 mV and the mV reading of the pH electrode in pH 7.00 buffer should be in the range of -30 to +30 mV. If the mV readings of the pH electrode are in the correct ranges, the pH electrode is capable of performing automatic buffer recognition. If the mV readings of the pH electrode are not in the correct ranges, the values of the pH buffers will need to be manually entered during a pH calibration.

    Those above or below the range of calibration are calculated by extrapolation from the top or bottom most segment. The displayed slope is an average slope of the separate segments. The slope may be outside the range normally expected for an electrode. For example, if the slope of one segment is low, then the average will be lower than theoretical, even though the response may be Nernstian over most of the range. The figure below is an example of a typical calibration curve using this method. Thermo Scientific Orion V pH with LogR Temperature Module ersa...

  • Page 33: About Logr Technology

    Appendix B About LogR Technology LogR Temperature Measurements Orion V Meter and pH with LogR Technology Module systems allow for direct temperature measurement ersa and temperature compensation from your pH electrode. With simultaneous measurement of pH and temperature, the patented digital LogR technology makes this possible using most standard glass pH electrodes. The system is based on using the electrical resistance of the glass sensing bulb as the temperature probe. The logarithm of the resistance of the bulb varies almost linearly with the reciprocal of the absolute temperature (see Figure 1). Almost all common pH glasses show a similar decrease in resistance with increasing temperature, and can be used with other meters. To maximize system performance and accuracy, use a ROSS pH electrode.

    Meter and pH with LogR Module’s ersa Electrode Diagnostics Electrode Trouble-Shooting Using LogR Technology Many factors affect the performance of your pH combination electrode. While the majority of problems seen in electrode performance relate to reference issues, changes over time in the sensing glass can negatively impact performance. Thermo Scientific Orion V Meter and pH with LogR Module system allows you to monitor these ersa effects. This can save time, helping to identify cases where cleaning and maintenance will not be able to rejuvenate your electrode. Viewing Electrode Resistance The pH electrode bulb resistance value can be found right on the measurement screen when LogR is selected for the temperature input.

  • Page 36: Initial Electrode Check

    By keeping track of the change in resistance (delta, as listed in the log example below), this information may be used to determine when to replace your electrode, before failure occurs, eliminating down time. Large Decreases in Resistance – When the glass pH membrane resistance is more than ten times lower than the expected resistance value (at a given temperature), it is often an indication of membrane crack in the bulb or shorting, leading to a total failure in function. If you see this type of change in the resistance reading, no further testing or care will resolve the problem. A new electrode will be needed at this point. Increases in Resistance – As the electrode ages, the resistance of the electrode’s glass bulb increases. Eventually, the aging of the electrode, and visible increase in resistance, manifests in a slower response rate, low slope, and reduced immunity to noise. At some point the resistance becomes “super high”. The Orion V Meter and ersa pH with LogR Module system’s diagnostics help you pinpoint the causes of your reduced performance and quickly show you the effectiveness of your cleaning and care processes.
