Hanna PH500 Series pH Controllers

Hanna PH500 Series pH Controllers The Hanna Instruments PH500 Series pH controllers are simple-to-operate, microprocessor-based process meters. 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 models of the Hanna Instruments PH500 Series pH controller are equipped with a bi-directional RS232 port. Push button password programming prevents tampering. The microprocessor memory is fully programmable and has a 3 month backup power supply. The Fail Safe Alarm system protects the Hanna Instruments PH500 Series pH controller against the pitfalls of process control, like power interruption or line failure. Quick 1, 2 or 3 point calibration at pH 4.01, 7.01 and 10.01 comes standard with the Hanna Instruments PH500 Series pH controllers. The temperature can be manually or automatically compensated for. Models of the Hanna Instruments PH500 Series pH controller 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. pH meters require regular calibration to perform at their optimal level. We strongly suggest purchasing calibration solutions. We offer both calibration kits and individual solutions to meet your needs.
