Digital Inline TDS - Titanium S3

Digital Inline TDS - Titanium S3

Titanium S3 is a in-line TDS meter, with 3 probes, which allows you to measure, control easily and precisely the level of the total dissolved solids (TDS) at 3 places of your choice, usually at the inlet, before the deionization cartridge and at the outlet of a reverse osmosis unit.

Reference: AA-TDS300S


It makes it possible, for example, to immediately see whether the water quality at the outlet of an osmosis system is pure or not.

Titanium S3 is designed with 3 titanium probes, which offers excellent corrosion resistance. It can be calibrated regularly to obtain accurate results. Its magnetic coupling makes it easy to install on the metal frame of an osmosis unit.

Titanium S3 is also a very good indicator for changing filter cartridges or the reverse osmosis membrane.

Titanium S3 automatically turns off after 3 minutes of non-use to preserve battery life.

Titanium S3 can be installed very easily using the "T" fittings Push Connect ¼" (included). Simply cut the tube where the measurements are required, insert the supplied fittings and then insert the probes.
