pH Transmitter with 4-20 mA Galvanically Isolated Output - HI8614

The HI8614N and HI8614LN are a water-resistant pH transmitters designed to be used with a standard high impedance pH probe with BNC connector. The signal is then processed by a special high impedance amplifier, which transmits an output current directly proportional to the input signal but independent of changes in load or cable capacitance.
  • Temperature compensation ensures fast, accurately compensated readings even during sudden temperature fluctuations.
  • Water resistant design for use in process control.
  • HI8614LN has optional backlit, LCD display for easy viewing (no LCD on HI8614N)

pH and EC Transmitter with Isolated Output

The HI98143 is part of a family of blind transmitter that can be used in water treatment and hydroponic applications. These meters have inputs for both pH and EC probes. The pH probe input uses a common BNC connector while EC has a direct wire connection for use with Hanna's EC probes that incorporate an NTC sensor for temperature compensation.The HI98143 is available in four models based on the analog output signal required.
  • Blind transmitter for pH and EC (up to 10 mS/cm)
  • Choice of analog output in voltage or current
  • Powered or loop powered analog outputs
