The RT-790 is an in-line and low-cost testing device to monitor the quality of pure water which is generated by reverse osmosis water filters. It measures the conductivity of water and converts it to be TDS reading. The measured TDS reading is compared to the pre-setting TDS value. The RT-790 turns on a RED light if the measured TDS reading is over the pre-setting TDS value. If it’s under the pre-setting TDS value, the RT-790 turns on Greenlight.


Feature :

* Automatic testing or manual testing

* Internal battery power

* Easy connected to most of reverse osmosis water filters


Connecting Fitting

Cut off the outlet tube (between the tank of the reverse osmosis water filter and faucet). Insert the tube into the quick fitting


Operating

Automatic testing:

a)Testing per hour.

c)If testing resistance value is smaller than setting resistance value, it will be recorded. After five times record, it will enter into a warning status and stop testing.


Manual testing:

a)Press the button for testing.

b)If testing resistance value is bigger than setting resistance value, the blue light will flash five times and enter into automatic testing model.
