Digital 3-in-1 water quality meter with TDS and EC values, LCD display, temperature and conductivity measurement (0–9999 ppm), drinking water quality monitor pen

Instructions for use: Before use, remove the electrode sleeve. Immerse the electrode in the test solution by pressing the button. Once the reading is stable, press the hold button and remove the electrode from the solution to read the value. After measurement, turn off the device and clean the electrode before reinserting it. Measuring range: Water quality meter 0–5000 ppm (TDS), 0–9990 s/cm (EC), 0.1–80.0 °C / 32.0–176.0 °F (temperature). Automatic shut-off: The blood glucose meter automatically shuts off after 5 minutes of inactivity to conserve battery power. Easy operation: The digital water quality meter features automatic temperature compensation; the temperature range is 0–80 °C (32–176 °F). Water quality measurements can be converted between TDS and conductivity. User-friendly design: The water quality meter stores readings for easy reference and documentation. The probe is simply immersed in the water, and the LCD display shows precise results within seconds. Versatile use: The 3-in-1 EC/TDS test pen is suitable for water purifiers and filters, food quality control, swimming pools and hot springs, aquariums, and hydroponic systems.
