PH502421-2 pH Digital Controller with Matching Pin and PID Control, 230V by Hanna Instruments

The pH 502 series of controllers offer many features to increase the level of control available in your plant. These instruments can be configured to utilize P, PI, PID controlling. With this feature, the pH 502 takes the place of three instruments that only allow one configuration each. The pH 502 line includes models that incorporate control through analog output to drive any compatible device, such as an electrovalve or pump. Models equipped with a solid state relay are also available to ensure maximum life of the switching device. Each model has a differential input for a grounding bar to extend electrode life. Several models come with an RS485 port, as well as analog recorder output.

Fail Safe Alarm System protects against power interruption or line failure. 1, 2 or 3 point automatic calibration and manual or Automatic Temperature Compensation complete the features of this controller.

  • Single or dual set point
  • SSR relay available
  • Control through analog output
  • PID control
  • Fully programmable
  • mA and VDC recorder output or RS485
  • Differential input for ground loop protection
  • Automatic three point calibration
  • Last calibration data
  • Automatic Temperature Compensation
  • Simple wiring with removable terminal modules
