How to use this TDS meter?
Step 1. Begin by smoothly removing the protective cap and powering on the meter effortlessly.
Step 2: Immerse the meter into the water, ensuring accurate measurements. (Note: Avoid submerging the immersion line beneath the water to maintain precision). Gently stir the water to eliminate any air bubbles, ensuring consistent readings.
Step 3: Allow a few moments for the value to stabilize, ensuring precision and accuracy. Once stabilized, press the hold button to capture the value with ease.
Step 4: Carefully withdraw the TDS meter from the water to read the accurate value displayed.
Step 5. Conclude by pressing the off button, preserving battery life. But If you happen to forget, no worries—this smart meter will automatically power down after 5 minutes. Such an intelligent design significantly extends the battery life, offering you long-lasting performance. Step 6: Rinse the meter with pure water post-use, then replace the cap for safekeeping.
