TDS EC digital pen and temperature allows you to display the set scale value found in the water in the large LCD.

TDS EC digital pen is an ideal tool for home water purifiers, softening plants, reverse osmosis, swimming pools, laboratories, aquaculture farms and freshwater aquariums

Selectable scales

• TDS in ppm or mg/l
• EC in microSiemens/cm2
• while temperature is always displayed 

LCD digital TDS meter is used to test the purity of mains water or reverse osmosis system, or the functionality of post osmosis resins.

Auto power-off function:

• Turns off the instrument after 5 minutes of inactivity to save battery power.

Automatic temperature compensation (ATC) function.

• When the instrument is in measurement mode.

You can switch between TDS and conductivity by double-clicking the SHIFT key and switching between Celsius and Fahrenheit temperature.

Powered by 1 3V CR2032 battery (not included) capable of processing about 1000 hours continuously - 5 minutes auto power off.
