Description

HI8931BN Conductivity Analog Controller with Input from Probe or Transmitter, 0.01 mS/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. 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

Order Information:

The HI 8931 series is supplied with mounting brackets and instructions.
