AutoAqua Titanium One Digital Inline TDS Meter TDS-100

Are you tired of big, boxy, hard-to-read TDS meters? So are we! That’s why we built the AutoAqua Titanium Series TDS meters. They are small, easy-to-use, and have a big bright screen to make checking your TDS fast and easy.

With a single push of a button, you’ll get an accurate reading of the TDS in your water!

The Titanium One TDS Meter is actually the smallest inline TDS meter available in the aquarium hobby. It uses a titanium probe, which provides excellent protection against corrosion, to measure the Total Dissolved Solids (TDS) in your water. 

The reason hobbyists measure TDS is to ensure the water produced by their reverse osmosis (RO) or reverse osmosis/deionization (RO/DI) system is safe to use in an aquarium. 

The Titanium One TDS monitor can be used to check the quality of your inlet or outlet water to help you determine when it’s time to replace the cartridges in your reverse osmosis system. This is the most common application for a TDS meter in our hobby and the Titanium One is ideal for the job with an accuracy of +/- 2%. 

It’s super easy to install, too. A ¼” push connect union tee is included to make setup a breeze. You can calibrate the Titanium One to ensure long-lasting accuracy. 

To conserve battery life, the unit will turn off automatically after 3 minutes of non-use. The battery is not proprietary, either. The Titanium One uses a common CR2032 lithium battery so when it comes time to change it, you should have no problem finding a replacement. Under normal use, the battery should last a year or more! There is also a low battery indicator on the display so you’ll never be left high and dry.
