pH 500111-2 single setpoint. on/off control. analog output. 230V

Product Description

 

 

  • Single or dual set point
  • Fully programmable
  • mA and VDC recorder output or RS232
  • Differential input for ground loop protection
  • Automatic three point calibration
  • Last calibration data
  • Automatic Temperature Compensation
  • Simple wiring with removable terminal modules

 

pH 500 series of controllers are simple to operate. microprocessor-based process meters packed with features. For more flexibility and better resolution for chart recorders. any two points between 0 and 14 pH can be chosen to correspond to the analog output spans. Several pH 500 models are equipped with a bi-directional RS232 port. Push button password programming prevents tampering.

The Fail Safe Alarm System protects the pH 500 against the pitfalls of process control. like power interruption or line failure. With pH 500 quick one. two or three point calibration at pH 4.01. 7.01 and 10.01 comes standard. The temperature can be manually or automatically compensated for. Models with RS232 output allow computer compatibility. a necessity for process control instrumentation. You can also choose from ON/OFF or proportional dosage to save on chemicals.
