The Xiaomi Mi TDS Pen is factory calibrated and does not require user calibration. Ensure it is properly cleaned and maintained for accurate readings.
The ideal TDS reading for drinking water is between 0-50 ppm. However, readings up to 300 ppm are generally considered acceptable for consumption.
To change the battery, remove the cap at the end of the pen to access the battery compartment. Replace the old battery with a new AG13 button cell battery.
Ensure the electrodes are clean and free from residue. Rinse the pen with distilled water before and after use. If issues persist, replace the battery.
No, the Xiaomi Mi TDS Pen is designed for use in cold water. Testing hot water can damage the sensor and affect the accuracy of the readings.
Clean the Xiaomi Mi TDS Pen after each use with distilled water. For thorough cleaning, use a soft brush to gently clean the electrodes every few weeks.
The Xiaomi Mi TDS Pen measures from 0 to 999 ppm, providing a wide range to test different water qualities effectively.
Ensure your pen is dry, clean, and stored properly. Regularly check the battery life and replace it if necessary to maintain accuracy.
A high TDS reading indicates a higher concentration of dissolved solids in the water, which could mean more minerals, salts, or impurities.
The Xiaomi Mi TDS Pen measures total dissolved solids (TDS) and does not identify specific contaminants. For specific contaminant testing, consider using specialized water testing kits.
