  • Page 4: General Information

    We are glad that you have chosen to purchase our TpH pH sensor. The TpH is based on the electrochemical measuring method with a measuring electrode and a reference electrode. This intel- ligent sensor stores calibrations internally. This enables a "plug-and-play" system without recalibration when the location or measuring transducer is changed.

  • Page 5: Health And Safety Information

    Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunction of the sen- sor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves.

  • Page 6: Warnings

    1.4 Users and Operating Requirements The TpH sensor has been developed for use in industry and science. The target group for the operation of the TpH sensor is technically skilled staff in plants, sewage treatment plants, water plants and institutes. The use of this device often requires the handling of hazardous substances.

  • Page 7: Proper Disposal

    • Drinking water monitoring Use in other media can damage the sensor. For the use of the TpH sensor in other media than those specified in this manual, please contact the customer service of TriOS Mess- und Datentechnik GmbH (support@trios.de).

    A line is put on the B line. The differential value between lines A and B is the decisive factor for the transmission robust- ness against conducted noise signals. The protocol used is Modbus RTU. A detailed description of the Modbus RTU protocol for TpH can be found in the annex. D01-068en201913 Manual TpH...

  • Page 11: Use

    The TpH are classified as consumables and therefore have a limited service life, depending on the user's application. Under normal conditions, the typical life span is about one year. The service life of the TpH can be extended by regular cleaning.

  • Page 13: Calibration

    5 Calibration TpH sensors that have not been used for a long time or that are new should be calibrated before measurement. Calibration should then be repeated at regular intervals. The calibration intervals depend on the type of application. Checks with standard solutions are recommended to determine the intervals.
  • Page 14 Rinse the sensor again with distilled water. • Immerse the TpH in pH4 buffer solution, the sensor head (black) should be immersed as completely as possible (the picture below shows the immersion depth in the beaker with the buffer solution as a red line). Otherwise, measurement fluctuations may occur.

  • Page 15: Measurement Properties

    Alkali error: at pH values above pH12, alkali ions (Li+, Na+) can cause lower pH values to be displayed, as the alkaliions are detected in addition to the H+ ions. • Flow can influence the measured value. 5.2.2 Temperature Compensation Temperature compensation is performed automatically by the integrated temperature sensor (Pt1000).

  • Page 16: Malfunction And Maintenance

    Avoid touching the sensors, as they could be damaged. If this is the case, the functionality of the sensor can no longer be guaranteed. The average lifetime of a TpH sensor is about 1 year. If difficulties occur during calibration, the sensor probably has to be replaced.
