The water quality tester is designed and manufactured to assist users to check the water quality of the reverse osmosis water purifier by them. It measures the conductivity of the water to judge if the water quality is in good or bad situation. If it's in the "bad" situation, it means the membrane of the reverse osmosis water purifier is not in proper function, and may not purify water well. It's better to have membrane be replaced immediately to avoid unsafe drinking water.
