1. Waterproof. Just like the digital probe thermometer, having a waterproof pH meter is (in my opinion) an absolute must. I don't have to worry about humidity getting into the unit and cleaning it under the faucet is dead simple and worry-free as there is chance of getting the wrong parts wet.
2. Goes to 140F instead of only 122F. I regularly use mine to measure 150-155F wort knowing that it may be slightly 'off' because the probe is rated to only 140F. If it's only rated to 122F it'll likely be off even more.
3. Automatic temperature compensation. The one you ask about doesn't adjust for temp so you have to manually do the math and need a separate thermometer to take the temp reading. The 122F max is just the temp of the liquid you're allowed to submerse it in.
4. Built in temp probe. The one you ask about doen't have a built in temp probe. I find this really handy sometimes.
That said, it is 1/3 the price and is most certainly better than using strips. It's point #1 I don't like as it basically makes it disposible. I promise it *WILL* stop working after a few uses if you use it in your kettles. If you always pull of a sample, allow it to cool, and are careful when measuring not to get steam on it and careful wash it, then it'll last longer. I don't like to have to be that careful. I hold mine completly under the faucet to wash it with the butt end facing up such that the water runs down the entire probe (easier to clean it this way). I've dropped mine in the wort. YMMV. I subscribe more to the "buy once, use a lifetime" mentality, but that's just me.

Actually, I believe I will purchase some strips and buy me some time to sock away the $ for the good meter and 3 solutions. Thanks for the input. I don't like being blind on the mash Ph. At least the strips will give me some feedback on what is going on...
