• 【Testing principle】: The measuring principle of the TDS meter is to measure the conductivity of water, which indirectly reflects the TDS value.
• 【Function】: Detect some impurities in water, such as soluble salts, ionic organic compounds, heavy metal ions and other elements, providing convenience for you and your family to obtain cleaner water.
• 【Easy to use】: Supports hold function, which can save measurement results for easy reading and recording.
• 【Automatic shutdown function】: Digital water tester automatically shut down after 5 minutes of no operation to save power.
• 【Application】: TDS meter can be widely used in aquariums, beverages, quality control, fish hatcheries, food processing, laboratories, schools, colleges, swimming pools, etc.

Description: A TDS meter is a cost-effective and convenient digital tool to instantly check your overall water quality, offering much convenience for you and your families to get a more clean water. How to Use: 1. Take down the protective cap and press the ON/OFF button for turning on. 2. Put it into the ready to test solution, and the solution height should not exceed 4cm (from the probe end to start) 3. Stirring the measuring probe in the solution to be tested gently for stable data reading. 4. After use, please wipe and dry the probe with cloth, and put on the protective cover for storage. Specifications: TDS Range: 0-9990ppm Temperature Range: 0-99℃ Accuracy: ±2% Battery Type: 2 * 1.5V LR44 Button Batteries(included) Size: Approx. 15.5*3*1.8cm/6.1*1.18*0.71in Weight: Approx. 70g Package Included: 1 * TDS Tester Note: 1.TDS (Total Dissolved Solids) is a measure of the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. 2.TDS measurements will influenced by temperature, therefore for temperature compensation to correct readings, please press the "hold" button for fixed numerical value in a few minutes. 3.The numerical value of TDS is bigger means the more water dissolve solids and the numerical value of TDS is smaller means the less water dissolve solids. Less the total dissolve solids, more purifying water for you.
