Description

pH, ORP, Temperature In-line Controller. 1/8 DIN, RoHS compliant, panel mount pH/ORP/Temp controller with 2 sets of programmable on/off relay and backlight. Extremely price competitive.

  • Easy to install 1/8 DIN plastic casing.
  • Clear LCD displays pH, mV or temperature with backlight.
  • Universal power supply input from 100 ~ 240 VAC.
  • Automatic buffer recognition of US and NIST buffer sets. Calibrated data is stored in memory and ready to for use on power up.
  • Automatic or manual temperature compensation.
  • Displays absolute and relative ORP.
  • Two sets of programmable on/off relays for pH or ORP &Isolated and reversible
    4 ~ 20 mA current output for pH or ORP allows it to be used as a proportional output.
  • RoHs compliant.
