  • Automatic temperature compensation
  • In operation mode „pH“ an automatic tempera turecompensation (ATC) is possible in the range 0 ... 105 °C if a temperature probe is connected. Otherwise a manual input of temperature is possible.
  • pH calibration
  • Buffer selection, temperature compensation and sensorrating a ccording to calibration result (from 10 ... 100 %) is
  • done automatically.
  • GMH 3511  2-point calibration with Greisinger buffer capsules (GPH 4, 7, 10)
  • GMH 3531, GMH 3551  Either 1-, 2- of 3- point calibration with Greisinger standard buffer, buffer according to
  • DIN19266 (A, C, D, F, G) or manual buffer selection.
  • Calibration interval (not for GMH 3511)
  • The device asks for a recalibration after a
  • selectable time period (1 - 365 days or inactive)
  • GMH 3551  Calibration history additional
  • ORP measurement (Redox)
  • There are 2 choices
  • „mV“  standard ORP or mV measurement
  • „mVH“  temp. compensated conversion to hydrogen
  • system acc. to DIN38404 part 6, table 1
  • based on the standard ORP electrode (e.g.
  • GE105 with Ag/AgCl system and 3 mol KCl)
  • used.
  • rH measurement  (except GHM 3511)
  • Calculation of the rH value by means of a ORP measurement and by manually entering the pH-value.
  • The pH-value may also be taken from a previous pH measurement.
  • Analog output 0 ... 1 V, not changeable 0 ... 1 V = 0 ... 14 pH or -2000
  • ... 2000 mV, connection via 3-pole jack socket Ø 3.5 mm,
  • resolution 13 bit, accuracy 0.05 % at nominal temperature GMH 3551  Analog output freely scalable
  • data logger (GMH 3551 only)
  • cyclic 10,000 data sets, manual  1,000 data sets (with measuring point input, 40 adjustable measuring point texts or measuring point numbers).
