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
