    Xiaomi Pluma De Prueba TDS para Calidad De Agua
    Mi hermana que es Ing, Quimica me pidio una de estas. Preguntas frecuentes¿Mide el pH?No, solo el TDS¿Qué es un TDS?Los TDS (Total dissolved solids) son la suma de los minerales, sales, metales, catiónes o aniones disueltos en el agua. Esto incluye cualquier elemento presente en el agua que no sea (H20) molécula de agua pura y sólidos en suspensión. Partes por millón (ppm) es la relación peso-a-peso de cualquier ion al agua.¿Qué se mide con el TDS?El término sólidos disueltos totales (TDS) describe el peso total de los componentes sólidos (minerales, sales o metales) disueltos en el agua por unidad de volumen que se mide en miligramos por litro (mg/L) o partes por misión (ppm).

    Interesting gadget
    What can I say? It works. I have no other data to compare the result to, as I have not done other tests on the water, but it does show almost 0 for distilled water and 55 for the tap water. So, it does what it's supposed to.

    Bom produto
    O produto vem tal como anunciado. A entrega também foi bastante rápida. Em termos do funcionamento o mesmo é muito simples, basta clicar no botão e colocar a pen na água, em poucos segundos dá-nos o resultado. O único senão foi as instruções apenas virem em chinês mas na Internet facilmente se encontra em inglês.

    i think i am getting obsessed with measuring different bottled waters! This tool seems to work well. My tap water hits 400+ while bottled waters measures between 200 and 250.
    Very good structure and quality.

    Nice Unit but user manual only in Chinese
    Good design, great packaging and seems accurate. The only downside was the instruction manual was only in Chinese. Simple to use but I am not sure if it requires calibration since I could not read the manual.
