    อุปกรณ์วัด Control System (Conductivity Analog Controller with Input from Probe or Transmitter 0.1 µS/cm resolution)

    HI 8931DN

    Conductivity Analog Controller with Input from Probe or Transmitter 0.1 µS/cm resolution

    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′).
