        Deutsch: Wasserqualitäts Tester
        Pros:
        Ja der TDS Pen erfüllt seinen Zweck, ins Wasser halten und anzeigen wie hoch der PPM ist. das war es auch schon.
        - kleine Größe, andere TDS Tester sind deutlich dicker, bieter aber auch mehr Funktionen
        - einfache Bedienung mit nur einen Knopf auch nicht sonderlich schwer

        Cons:
        - keine Hold Funktion, nimmt man den Stift aus dem Wasser ist er wieder bei Null
        - Ob die Werte richtig sind kann ich nicht sagen.

        TDS pen for hobby
        Pros:
        - good value for the money
        - Xiaomi built-in quality
        - accurate measuring
        - I have measured water from tap with value of 220
        - carbon filtered water was showing 170
        - black tea was about 235 and when I added Pepsi, it was more than 330

        Cons:
        - it just tells you about quality of the water, but does not indicate whether it is harmful or not
