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 analogue output spans. Several pH 500 models 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.
