A monitoring device for a reverse osmosis purification system of drinking water comprising a microprocessor that controls the overall operations of the monitoring system, a LCD indicating circuit that relates information to maintenance personnel, a detecting means that analyses related data for determining the condition and extents of clogging of the reverse osmosis filtration elements, a warning means that produces verbal or musical sound for warning consumers about the clogged condition of the reverse osmosis filtration elements, and a power switching means that cuts off electricity supply to the water pump of the purification system. In operation, the reverse osmosis filtration elements will be clogged by impurities after being used for a period of time. If the reverse osmosis filtration elements are clogged, the monitoring device will make a sound to warn of such condition of the reverse osmosis filtration elements and will eventually cut off the power supply to the pump for stopping water delivery if the clogged reverse osmosis filtration elements are not replaced after a certain period of time.
