*Make sure you always drink pure water.

Ⅲ. Features 

1. Digital display: accurate to 3 digits. Temperature compensation accurate to 0.1℃.

2. Backlight function: green backlight while TDS value ≤40,red backlight while TDS value >40.

3. Auto-lock: TDS value stabillizes 4 seconds, instrument automatically lock readings.

4. One Touch function: Forget to turn off the power, automatically shut down after 5 minutes.
