      TDS / Conductivity Controller AC880

      The AC880 C01& C02 Conductivity Controller can be configured to measure EC (Electrical Conductivity) and/or TDS (Total Dissolved Solid) or other indirect scales during the installation, it’s also possible the visualization of resistivity.

      The AC880 C03 Conductivity Controller can be configured to measure EC or TDS.

      The sensors in our catalogue allow the visualization of the temperature value as well, making the instruments suitable for any type of application and installation.

      Conductivity Controller AC880 (C01 & C02):

      • Range:
        • EC scales related to the K of the cell
          K=1 20.00/200.0/2000 μS – 20.00/200.0 mS
        • TDS scales related to EC scales
          100.0/1000 ppb; 5.00/10.00/50.0/100.0/500/1000 ppm; 5.00/10.00/50.0/100.0/1000 ppt
        • Resistivity scales related to EC scales
          5.00 – 999.99, 0.500 – 99.999 MΩ; 50.0 – 9999.9, 5.00 – 999.99, 0.500 – 99.999 kΩ; 50.0 – 9999.9, 5.00 – 999.99, 0.500 – 99.999 Ω
        • Temperature scales
          -10.0 – 110.0 °C, 14.0 – 230.0 °F
      • Display: The display shows the values of the measures and the messages which guide the user through set-up, configuration and during normal operation.
      • Keyboard: There are dedicated keys to directly access zero and sensitivity calibration as well as set point configuration
      • Two Filters Software: The user can set two filters in order to obtain a stable reading and a faster response to the variations of the measurement in the process.
      • AC880 operating modes: The meters can operate in automatic, measure or simulated mode so to facilitate start-up or maintenance.
      • Dual Analog Outputs: Can be addressed to any input and programmable 0/4 – 20 mA on two points of the scale. They allow PID control or transmission of the measured values.
      • Two On/Off Regulators: Independent and addressable to any input with programmable set point on the scale.
      • PID Output: During PID control through the analog output, the level of the actuation is displayed. The user can select an FM regulation (pulse frequency) or WM (pulse width) addressed to the assigned relay.
      • Logic Inputs: Two free voltage contacts in AC880 can generate a hold or alarm condition.

      Conductivity Controller AC880 (CO3):

      • Range:
        • 0 ÷ 2.000/20.00/200.0/2000 μS;
          0 ÷ 2.000/20.00/200.0/2000 mS;
          0 ÷ 1.000/10.00/100.0/1000 ppm;
          0 ÷ 1.000/10.00/100.0/1000 ppt;
          -10.0 ÷ 110.0 °C , 14.0 ÷ 230.0 °F
      • Display: The display shows the values of the measures and the messages which guide the user through set-up,  configuration and during normal operation.
      • Keyboard: There are dedicated keys to directly access zero and sensitivity calibration as well as set point configuration.
      • Two Filters Software: The user can set two filters in order to obtain a stable reading and a faster response to the variations of the measurement in the process.
      • Single Analog Outputs: The 4-20 mA current loop is galvanically isolated, so that can be interfaced directly to a PLC or data acquisition cards.
      • Logic Inputs: A free voltage contact can create the hold condition.
      • AC880 operating modes: Can be configured to operate in analog or digital mode. The digital mode is always active in analog mode.
