Bluelab BLU8000 PENGTB Grower's Toolbox with pH

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.🤘🏼

Das Produkt funktioniert einwandfrei. Mir hat es die umweltfreundliche Verpackung besonders angetan, kein unnötiges Material verwendet. Alle Infos inklusive Anleitung wurden innen und außen auf die Packung gedruckt. Stark!

2/18/25 Update: BlueLab reached out to me to resolve the issues I was having. They ended up sending me a new pH pen and shared some information on a few things worth considering. My new pen arrived and the storage cap was still moist with storage solution (this is a good thing). The new meter does work better than the original one, but I also suspect that my tap water has "low ionic content" which can cause pH readings to drift (this was also mentioned by BlueLab in their communications with me). I have found that the first readings of the day with the BlueLab pH pen can be a bit low when checking tapwater at my house. If I add nutrients to the water, the pH readings are much more definitive and easy to take. I believe this is to do with the ionic content. I experienced similar behavior with some other, cheaper pH meters. The BlueLab pen reads the calibration solutions quickly and accurately. My advice to anyone new to and/or serious about measuring pH, buy yourself some pH drops (General Hydroponics sells an affordable kit) so you can definitively measure your pH using a visual color matching method and compare to your meter readings. I found that the drops worked the same every single time without error or question or waiting and gave me more confidence in working with electronic pH meters. With some experimenting, I was able to figure out how to get repeatable and accurate readings from the BlueLab pH pen; Sometimes getting a reading of my tapwater that I am confident in takes a few tries. Why get a pen if drops work so well? The color shades when using drops are distinguishable between 6.0 and 6.5 for example, but identifying in between can be difficult to judge. The BlueLab pen gives me 0.1 resolution/accuracy that is needed when doing hydroponic gardening. Having both ways to check pH is ideal. I suspect that pH pens are generally not terribly expensive to manufacture, but it is costly to have a support team available to reach out to communicate with and help customers with their products. Ultimately, BlueLab came through with service, something that is rare these days. I appreciate this and have raised my rating to 5 stars. I really like the BlueLab pen cap, with the sponge that keeps storage solution on the bulb, and the rope used to connect it is also helpful when taking pH samples in a bucket. I do however, wish the the base of the cap was a bit wider so the pen could stand up on its own more reliably. I also wish the meter displayed down to 0.01, not because I need more accuracy, but because I want to see what the current measurement trend is doing (going up/down). The auto off timer also feels a bit short, but I suppose that is both good and bad. 1/10/25 (Original Review) I really wanted to like this expensive PH meter. Sadly It came with a dry probe so I soaked it as directed for 24 hours. Calibrated it 3x with Bluelab 4 and 7 solution but readings would drift for several minutes after each calibration. Tap water would measure at 6.4 right after calibration but leaving the pen in the same sample of tap water the reading would drift up to 7.5 after several minutes. It would never read the same value twice. Just a few minutes after calibration it would read the calibration solution several tenths lower than it should. I bought this expecting accuracy, not games. Returning.

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.
