Description
The smart and essential digital inspection pen and device for every home, model (TDS-3), designed to measure the total dissolved solids in water (Total Dissolved Solids) and determine the purity and quality of drinking water. This device is the approved and essential tool for monitoring the efficiency of domestic water filters and reverse osmosis (RO) systems, allowing you to accurately know the water quality and determine when to replace the membrane cartridge and filters without guessing.
The device features a built-in thermal sensor that provides automatic temperature compensation to ensure reading accuracy in different environments. It also includes a clear LCD screen and three simple operation buttons: ON/OFF and Salinity button, Water Temperature Measurement button (TEMP), and Reading Hold button (HOLD). Thanks to its lightweight design and pocket-friendly size, you can easily and quickly use it to test tap water, bottled water, aquariums, and hydroponics.
Correct Usage Method:
-
Remove the lower protective cap of the device.
-
Press the ON/OFF button.
-
Dip the lower end of the device into the cup of water to be tested (up to the maximum permissible immersion limit of 2 inches, and avoid fully immersing the device).
-
Wait 30 to 45 seconds for the reading to stabilize on the screen, then press the (HOLD) button to save the result and read it comfortably.
-
After use, shake the device to dry it from water residue or wipe it with a soft cloth, then reattach the protective cap.
