La calibration est simple. Par contre, par rapport à une sonde témoin, il est extrêmement lent. Il faut compter presque 10 minutes pour que le pH final soit affiché. Il faut donc le mettre longtemps pour à avoir le bon pH. Après 6 mois et une utilisation par mois, il deconne complètement. Mauvaise qualité

Esperaba fuera algo sumamente sencillo de usar, y necesita ciertos insumos que los trae incluidos pero al terminarse no se donde los podré conseguir. No supe como usarlo.

Product does not work out of box. Just reads 0.00. So I calibrated, well tried to. Still no reading. Just random numbers then zeros out. Vivosun products are usually pretty good but this is crap. UPDATE: Tried soaking the electrode in ISO alcohol for a few hours, rinsed, tested on test bottles...and it works perfect. Did a recalibration with no problems at all. Held readings and is pretty accurate (+\- .01).

Produto correto para quem não precisa de muita precisão. Dá para fazer a calibragem de 1 etapa (pH neutro), mas não de 3 etapas (com pH ácido e básico), apesar o produto seja previsto para isso. Segui exatamente o manual, assisti também vídeos, mas nada: o produto nunca entrou em modo de 3 etapas de calibragem. Pode ser que minha caneta esteja com defeito.
