pH/Temp Industrial Online Controller 6312PTB


  • Graphic LCD with manual backlight displays pH, temperature, relay status, and transmitter current mA output.
  • Automatic buffer recognition of US and NIST buffer sets.
  • Calibration data is stored in memory and is ready for use on power up.
  • Two sets of isolated and reversible 4-20 mA current output for pH and temperature allows it to be used as a proportional output.
  • 4 programmable on/off relays: 3 for pH and 1 for temperature.
  • RS-485 output for remote access allows multiple units to be connected and ganged together.
  • Password protection.
  • IP65.
