The Titanium S1 TDS monitor can be used to check the quality of your inlet or outlet water to help you determine when its 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 S1 is ideal for the job with an accuracy of +/- 2%. 


Its 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 S1 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 youll never be left high and dry.
