PH transmitter HG111C

Function

  • Simple menu setting
  • The correct data and other information will not lost when power off
  • PH Calibration and electrode offset adjustment
  • Automatic temperature compensation (ATC)
  • If without ATC, instrument has manual setting for temperature compensation
  • All relays with 1 to 2000 seconds time-delay adjustment
  • Return difference of alarm (relay output) is adjustable.
  • Relay output is programmable
  • Relay 1 can be set into clean the relay
  • PH/ORP operation mode is switchable
  • LCD display
  • Optional output: one-way 4-20mA output (electrical isolation output), two-way 4-20mA output, RS485 communication.
  • Hold function, frozen output current (4-20 ma) and release control relay
