VERSATILE The TDS meter is suitable for home water quality testing, such as drinking water, tap water, aquariums, ponds, swimming pools, filtered water, bottled water, which is convenient for vegetable growing or aquaculture.
Multi-mode switching: click the shift button to switch between TDS and EC, the meter will display the TDS value at the factory; 2 consecutive touch of the shift button, Celsius Fahrenheit switching, the meter is factory preset to Celsius.
Measuring range: TDS: 0-9999ppm; EC: 0-9999us/cm; Temperature: 0.1-80.0°C, Fahrenheit: 32.0-176.0°F, Accuracy: ±2%.
EC meter calibration method: 1. Prepare tools: solution with known value 2. Press the first ON/OFF switch to turn on the device. 3. Remove the electrode shield. 4. Place the electrode in a solution of known value and gently swing the solution to remove any air bubbles around the electrode. 5. In the detection state, press and hold the middle button for 5 seconds and then press buttons 1 and 3 to adjust the known solution value up and down. This completes the calibration. The calibration standard solution is EC: 1413 μS/cm (not included)
AUTO SHUT OFF FUNCTION The TDS meter stores the reading for easy reading and recording, and shuts off after 5 minutes of inactivity to extend battery life.
3-in-1 water quality tester: the water meter for drinking water consists of a TDS meter, an EC meter and a thermometer. Three different measurement requirements can be met by one meter. (The batteries are packaged separately, which can effectively avoid loss of battery power)
