The warranty period for instruments is 24 months. If a service contract is taken out within 6 months of purchase, the warranty period is extended to 60 months.
  • Page 93 Warranty, liability and complaints To avoid or limit consequential damage, it is therefore recommended to design the control loop such that a malfunction in an instrument results in an automatic change over to the backup control system; this is the safest operating state for the environment and the process.

  • Page 99: Appendix B Concentration Curves

    Appendix B Concentration curves B.1 Concentration measurement ranges For the solutions listed in Table 20, the transmitter determines the concentration from the measured conductivity and temperature values in % by weight. The measurement error is made up of the sum of measurement and the stored accuracy of the concentration curves.

    The following ATEX safety instructions pertain to the electrodeless conductivity sensors, model 3700E-series, types 3708E2T, 3727E2T and 3728E2T manufactured by Hach Company. These sensors are described in the EC type-examination certificate TÜV 07 ATEX 553601 as part of the Transmitter si792x E.
  • Page 110 If it is still not possible to perform a clear assessment on safe usage, or applications areas other than those described are intended, then the application must be clarified with Hach Company/ Hach Lange GmbH. 5. A condition for the safe usage of sensors is compliance with the stated environmental conditions and temperature ranges.
