What is a TDS meter, and why should I use it?
A TDS meter measures Total Dissolved Solids in water — minerals, salts, and metals. Knowing your TDS level helps you check water purity, monitor filter performance, and ensure safe water for drinking, aquariums, hydroponics, pools, and more.
-
What TDS level is considered “good” or safe?
Pure water typically reads 0–50 ppm, while tap water often ranges 50–300 ppm. The lower the reading, the fewer dissolved solids are present. We include a TDS level guide with your meter to help you quickly understand your results.
-
How accurate is this TDS meter?
Our meter features lab-grade sensors with ±2% accuracy, ensuring highly reliable readings. For the best results, always rinse the probe in distilled water after each use.
-
Can this meter be used for anything besides drinking water?
Yes! It’s perfect for aquariums, hydroponics, pools, spas, and checking the performance of water filters and RO systems. Any liquid that isn’t oil or alcohol-based can be tested.
-
Does it come ready to use? Do I need calibration?
The meter comes fully calibrated and ready to use out of the box with extra batteries included. Just remove the protective cap, turn it on, and dip it in the water sample — results appear in seconds.
