pH Controller APH480

APH480 pH Controller can be paired with sensors and submersible probes in our catalog to allow for visualization of the temperature value as well as the pH, making the instruments suitable for industrial and heavy application.

pH Electrochemical Sensor Probes

aph480 ph controller electrochemical sensor options

APH480 (C01 & C02):

  • Range: 0.00  14.00 pH, -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.
  • APH480 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 that can generate a hold or alarm
    condition.

APH480 (C03):

  • Range: 0.00  14.00 pH, -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.
  • APH480 operating modes: Can be configured to operate in analog or digital mode. The digital mode is always active in analog mode.
