Very good, best Ph packets I’ve used.
Worked very well. Ph level was perfect compared to another brand I used. Pretty good value. It’s super accurate. The brand is one that I trust and have always. I only had to do it twice just to make sure and it came out perfect both times.

Compré este paquete para calibrar mi medidor de pH y la verdad funciona excelente. Cada sobre trae la cantidad exacta para preparar 250 ml y los valores (4.00, 6.86 y 9.18) vienen muy bien marcados. Se disuelven rápido, no quedan residuos y la calibración queda precisa. Me gustó que vienen muchos sobres, así siempre tengo de repuesto cuando necesito volver a calibrar. Por el precio y la cantidad, vale totalmente la pena. Muy recomendado si quieres lecturas más exactas en tu acuario o cualquier otro uso.
