pH controller pH controller - pH 500 series


pH 500 series of controllers offer exceptional value for your money. They are simple-to-operate, microprocessor-based process meters packed with features for the biological laboratory. For more flexibility and better resolution than 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 RS232C port. Push button password programming prevents tampering. The microprocessor memory is fully programmable and has 3 months backup power supply. 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 1, 2 or 3 point calibration at pH 4.01, 7.01 and 10.01 comes standard. The temperature can be manually or automatically compensated for. Increased automation has made computer compatibility a necessity for process control instrumentation.
