Process pH controller

pH/mV digital industrial transmitter dual digital display

The pH transmitter converts the output of a pH electrode, with temperature compensation, into a signal at 4÷20 mA.

  • The pH electrode input circuit is galvanically insulated against the 4÷20 mA output signal
  • An LCD indicator allows viewing of the process signal value and of the various parameters
  • The accurate design and choice of components make the instrument precise and reliable for a long working life
  • The instrument works with a pH electrode or Redox and a temperature probe (Pt 100 sensor, 100 Ω at 0°C)
