  • Page 3 A quick check with the PH-T shows you whether the trouble is really located in the sensor. On the other hand, the PH-T can be used as an ideal sensor to check instruments and cable connections. No need for buffer solutions - the PH-T simulates electronically the measuring signals a sensor would give in various solutions.

    PH-T. By use of the scroll keys of the PH-T you can set an arbitrary value within +/-1500mV. Your instrument must react within a few seconds to any changes and finally show the same value as the PH-T.

    58 mV/pH, and a zero point of 0mV. 5 - Test By use of the scroll keys of the PH-T you can set an arbitrary value within pH 0 - 14. Your instrument must react within a few seconds to any changes and finally show the same value as the PH-T.

  • Page 7: High Resistance Test

    Press the key labelled “MegaΩ“. “MΩ“ in the display indicates that the high resistance has been activated. Focus on the value displayed by the PH-T: if it drops significantly, e. g. to approx. half its original value, then the measuring system does not provide the required high resistance.

    1 - Connect Connect the sensor to the PH-T using the COAX cable. 2 - Switch on Switch on the PH-T by pressing key “ON“ for 5 seconds. NOTE Switch-on is delayed to prevent accidental activation during transport. 3 - Select sensor test Press key “F“...
  • Page 9 Interpretation of the mV signals of pH sensors The following table shows the mV values an ideal sensor would give in various buffer solutions: mV ideal mV ideal -116 -174 -232 -290 -348 -406 If your sensor does not show exactly those values, don´t worry - it simply means that your sensor does not have a slope of 58mV/pH and/or that its zero point is not exactly pH 7.

    4. Batteries and accumulators At works the PH-T is equipped with a 9V battery. This will last approx. 72 hours when used for simulation (instrument test). When used for measurement (sensor test) or high resistance test, power consumption is higher.
