Bluelab PENPH pH Pen Fully Waterproof Pocket Tester, Easy Calibration (Twо Расk)

Me gusto, es fácil de calibrar. Te avisa cuando se necesita calibrar, lo único difícil es conseguir el humectador de sonda. Pero de ahí en más es un gran aparato.🤘🏼

Uno dei migliori misuratori di ph per l'acqua, il prezzo è alto, ma la qualità è eccellente

En este caso, la reseña va dirigida al Ph y su importancia en el agua. Sea de acuario, grifo, botella u otro líquido (aquí habría que pasarla por un limpiador o cleaner), si se tiene un sistema de suministro de CO2 en un acuario con sonda fija o no se tiene nada, saber el ph en todo momento es crucial. La sonda ya peca de algo esencial, tres cifras significativas. Pero a cambio te devuelve dos cifras exactas. No hay error. No hay que seguir con líquidos. Y Amazon la tiene a un precio ridículo. Así que, sin más, es la sonda para acuariofilia y otros hobbys o usos que se le quieran dar.

I dont know how old the one I was given 2nd hand was, I used it for 4 years. when I lost trust in it due to reasons, I purchased this one myself, as in, willing to spend money on it over the cheaper ones... comes with calibration fluid sachets. Great product.

This PH Pen is a definite must have for any growers out there. I rarely give 5 stars but this is one of the very few items worth 5 stars. I use this daily and wouldn't trade it for any other PH pen. It is expensive yes absolutely, the question is how many cheap ones you want to buy before getting this one. Don't waste your money with cheap ones. It's water proof and durable. It will last and you will be confident you are getting the desired PH. Strongly suggest this item. You want to know how tuff it is? After I decided to take a break last year I stored all my equipment in large storage bins. I was suppose to store this in the basement but I accidently stored everything in a shed outside for the whole winter and summer. When I realized what I had done I took everything out and let it get back to room temperature. My Bluelab pen had dried white solution on the probe and I was sure it was done. To my surprise after rinsing and testing my pen, not only was it working but it was still calibrated and accurate.
