If you have made the jump to All-Grain then probably, at some point, you have considered getting a pH meter.
Knowing how to read and adjust the pH of your brewing water and mash can set apart good beer and great beer. It can also aide in re-creating a batch, if that’s your thing.
I was recently sent the Hanna HALO wireless pH sensor for review.
Here's a quick trailer for the product if you haven't seen it yet.
If you are considering a pH meter then most likely you already realize that most manufacturers recommend regular calibration, therefore you have already accepted the fact you will need buffer liquid, so I won't be covering the buffers, however I was sent the proper buffers to calibrate the demo unit.
It should be noted that the meter also comes with small packets of buffer fluid (enough for two calibrations).
Personally I liked this meter. The integration with my phone was cool and because the app keeps record of the readings, I do not even have to remember to write them down.
- The calibration was simple and I found the app easy to use.
- The app is compatible with Android and IOS.
- The construction is elegant and there is just something pretty damn cool about seeing the little blue ring light up when I push the button.
- The body is titanium and it has a built in temperature sensor to do automatic temperature conversions.
- The glass inside is high-temp glass so it should stand up to your mash temperatures.
Let me just say it was a pleasure to use.
- Probably the biggest con is the price, clocking in at $225.00, this is not your everyday piece of equipment.
- The electrode cannot be replaced on this unit so when its done, its done.
- Also, in my experience it was a little slow to stabilize in its temp reading which puts the temperature converted pH all over the place. However, the temperature can be set manually and that seemed to fix the issue.
- For the price, I think it should have come with some kind of protective case, other than the box it comes in, (although this could be just because it was a demo unit).
- The high temp glass is only good for up to 176 F so don’t use it during a boil and don’t treat it like a hydrometer or floating thermometer because the electronic side is not sealed.
Overall I like this meter. I think that it has some really cool features and it comes from a long trusted name in laboratory equipment.
I do not think it is a good fit for someone just getting into all-grain brewing or even just getting into testing pH.
For me, it's biggest downfalls are it’s price and longevity.
Other than those, I think it would look really cool during a brewday. It would help tremendously if you are not that great at writing down your readings.
Finally, it would be a pretty awesome bragging piece for your brewing kit.
If the price does not bother you, then maybe this meter is for you.
