VIVOSUN 3 in 1 pH Pen Digital pH Tester Meter

Stopped working after a few months

المنتج ذو قياسات خاطئه لا انصح بشرائه

I got it yes it was very good

apresentou problema com menos de dois meses. nao esta preciso e sem confiança

Tut seit über einem Jahr nur mit anfänglicher Kalibrierung verlässlich was es soll. Wüsste nicht, warum man mehr Geld dafür ausgeben sollte. Zur Sicherheit nach dem Kalibrieren einfach sein Leitungswasser messen und schon kann man jederzeit überprüfen, ob der PH wert noch korrekt angezeigt wird

I usually use a different meter...but that one was not working (I had let it sit too long and I could not calibrate it) so I went looking for a good meter. I landed on this one as it was highly recommended, so I figured why not. So I began my grow Back in Sept with this dual pen and as you can see, it's been amazing throughout the entire grow. I am about a week out from harvest. When I say she works really well, I mean she works really well! You do kind of have to get used to calibrating it but after that it's a breeze. If you need a good pH pen and a TDS meter, I highly recommend you grab yourself one of these.
