DO9403T-R1 – pH / mV Transmitter
Brand: Delta OHM S.R.L.DO9403T-R1 pH transmitter converts the output of a pH electrode, with temperature compensation, into a 4…20 mA signal.
The pH or Redox electrode input circuit is galvanically isolated from the 4…20 mA output signal.
An LCD indicator allows to display the value of the process signal and the various parameters.
The accurate design and choice of the components make the instrument precise and reliable over time.
The instrument works with a pH or Redox electrode and a temperature probe (Pt100 sensor, 100 Ω at 0°C).
