DO 9785T/DO 9765T pH transmitters, Merk : Deltaohm

DO 9785T/DO 9765T pH transmitters convert 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 in conjunction with a pH electrode or Redox and a temperature probe (Pt 100 sensor, 100 © at 0°C). Technical characteristics Combined electrode input pH -1,00 pH...15,00 pH (-500...+500 mV) ORP -1999...+1999 mV Input impedance >10 Tohm Cable length
