Water Resistant Design This unit is water resistant and splashproof as you are going to drop this into a pool of sanitiser the moment you purchase it. Digital Triple Point CalibrationCheaper pH meters only have single or double point calibration. For brewing we often operate over a large range right down to 2.5 for testing sanitiser solution and high up for alkaline cleaners. We also need the pH meter to be accurate in the mid range for brewing. As a result we have got triple point calibration. The calibration is completely digital and can be done in 60 seconds. No calibration screws that you need to turn or anything like that. Just put the pH meter into the buffer solution that comes included and then hit the calibration button. It's as simple as that. Replaceable ElectrodeHome brewing puts a lot of stress on the electrodes. Especially if you are testing hot wort directly from your mash tun. If you know anything about pH meters you will know that the electrodes are not difficult to damage in a brewing environment and they have a tendency to fail over time. Why spend all this money on a good quality pH meter if you can't replace the electrode. This pH meter has a replaceable electrode so you can just remove it and put on a new one if you damage it. Includes Buffer SolutionThis includes 3 packs of buffer solution. Just add water and store in a glass jam jar and the buffer solution will last almost forever. Automatic Temperature Compensation (ATC)Any good quality pH meter you get will include ATC. This additional feature means the probe needs to have a small temp probe at the end so it can compensate for high or low temperatures. Lets face it, you are not going to wait for your wort sample to cool down to 20C are you. That's why this is absolutely necessary. Water Proof CapThe main reason why pH meters start to fail over time is they are incorrectly stored. If your pH meter is left with a dry probe the KCL solution evaporates through the glass membrane. This will cause incorrect pH readings. The cap on our pH meter has an o-ring and creates a water tight seal. It's amazing how many pH meters don't have this basic function meaning your probe gets destroyed very quickly and you are back to purchasing another unit or probe. To keep your electrode in best possible condition we recommend you clean with water then store in KCL storage solution inside the cap then push the cap on tight so it seals it up. This will keep your readings accurate for ages.
