Hanna Conductivity Analog Controller with Input from Probe or Transmitter, 0.1 µS/cm Resolution - HI8931DN

HI8931DN Conductivity Analog Controller with Input from Probe or Transmitter, 0.1 µS/cm Resolution by Hanna Instruments

HI 8931 is a panel mounted conductivity controller designed for simplicity of use. For in-line applications, use the HI 7635 probe, while for tanks the HI 7638 with external threads is recommended. These probes are provided with a built-in NTC sensor for temperature compensated conductivity measurements.

HI 8931 also features a direct connection up to 20 m (67'), without needing to amplify the signal to the conductivity probe.

Using the HI 8931 in conjunction with a 4-20 mA output transmitter (HI 8936 or HI 8936L series) will assure a strong, interference free signal at distances up to 300 meters (1000').

• Both electrode and transmitter compatible inputs accepted
• Selectable manual ON, OFF and automatic dosing control with indicator
• Built-in auto-diagnostic function for offset and slope
• Both 4-20 and 0-20 mA output user selectable, all in one instrument
• Backlit LCD
• Transparent splash-proof cover included
• Operational mode LED indicators
