Pas cher mais très lent
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

Meter Accuracte down to One tenth
Although it may be a little delicate to calibrate upon first time using. Insure solution temperature is ~75 degrees F. Measure out 250 ml distilled water. Insert the meter into a cup pour into another cup until you reach the line on the meter. Turn meter on holding down the calibrate button for 5 seconds then release. Press Cal button one more time. I did not get a display showing "cal" like some of the YT videos. This generates confidence in the meter concerns. However, I had a lab tech at the university check the calibration in a buffer solution of 7.0 and the meter showed 6.97. First pH meter that works and provides accurate results.

Opinión con poco criterio
Buscaba un medidor de ph con poco tiempo para comparar precios, y sin aparatos de medida para comparar su exactitud. De los 3 sobres de calibración sólo usé 1 (el de 6.68, que es lo más cercano a lo que quiero medir) Curiosamente, cada vez que lo enciendo empieza en 14...y tarda unos 2 minutos en llegar a la medida. Las instrucciones "regulinchi", pero en Youtube hay tutoriales magníficos. Creo que he pagado 3 euros más por la marca (por eso no le doy 5 estrellas).
