Description: The digital TDS tester is used to test the purity and quality of filtered water, verifying its performance. To ensure you always drink pure and safe water, the TDS tester is recommended for every household. Features: Made from durable, high-quality materials, the simple, single-switch design is easy to use. The TDS tester can be used in: water purifiers and filters, food liquids (vegetables, fruits) and beverage quality control, swimming pools and spas, aquariums, hydroponics, etc. The four electrolytic bars (two iron bars, two aluminum bars) form two groups of positive and negative poles (each group has one positive and one negative pole).
