How do I use the digital TDS meter?

Simply remove the protective cap, turn on the meter, submerge it into the water up to the maximum immersion level, and read the stable ppm measurement on the screen.

What does the TDS number actually mean?

TDS stands for Total Dissolved Solids, representing the total amount of mobile charged ions in water. Lower ppm numbers generally indicate purer water, and our included guide card helps you interpret the results.

Does the meter require manual calibration?

It comes pre-calibrated from the factory for immediate use. It also features automatic temperature compensation to maintain accuracy across different water temperatures.

Can I use this tester for fish tank and hydroponic water testing?

Absolutely. It works for drinking water, aquariums, hydroponics, pools and tap water.
