The AutoAquaDigital Inline TDS Titanium S1 is a compact and accurate Dissolved Solids (TDS) tester designed to monitor the quality of RO water at the inlet or outlet of your reverse osmosis unit. Its corrosion-resistant titanium probe and clear digital display make it an indispensable tool for any demanding aquarist.
The Digital Inline TDS Titanium S1 fromAutoAqua is a highly reliable electronic measuring device that is ideal for continuously monitoring the quality of the RO water in your aquarium system. Thanks to its titanium probe technology, it guarantees precise and durable measurements, while being perfectly resistant to corrosion.
The Titanium S1 measures the total dissolved solids concentration (TDS) in parts per million (ppm) and instantly tells you if your reverse osmosis membrane is performing optimally. Installed at the outlet of the osmosis unit, it allows you to know when to replace your cartridges or membrane to maintain water of impeccable purity.
The installation of the Titanium S1 takes only a few minutes thanks to the included 1/4" Push Connect T-fitting . Simply cut the hose at the desired location, insert the fitting, and then connect the probe to it. Its magnetic back panel allows for easy attachment to metal surfaces, such as the frame of your reverse osmosis unit.

The Titanium S1 can be used to measure the level of dissolved solids (TDS) in water, especially at the outlet of a reverse osmosis unit. It instantly indicates whether the produced water is pure or if the filters need to be replaced.
The Titanium S1 can be installed at the inlet or outlet of your reverse osmosis unit, depending on the desired measurement. It connects easily with its included 1/4" Push Connect "T" fitting.
The titanium probe offers excellent corrosion resistance and ensures high durability, even in a humid environment. It also allows for stable and accurate measurements over time.
Yes, the device can be calibrated regularly to maintain optimal accuracy. This allows reliable measurements to be obtained, especially during the maintenance of the osmosis unit.
The TDS meter automatically shuts off after about 3 minutes of inactivity, saving battery life and extending its life.
If the Titanium S1 has a high TDS value at the outlet of the reverse osmosis unit, this indicates that the membrane or filter cartridges are no longer effective and need to be replaced.
The kit includes a Titanium S1 TDS meter, a 1/4" Push Connect "T" fitting, and a pre-installed CR2032 lithium battery for immediate commissioning.
