What is your recommended meter for basic home brew use? What's the life of a probe on something like the 101 if it's taken care of.
Let's see, I've had my MW-101 for about 5 years and the original probe is still calibrating and performing well. I do store the probe submerged in KCl storage solution and I never put it in hot liquids. I can recommend this meter. I do like the fact that it is an analog meter and it is not subject to the whims of the software or hardware of a digital version. But its probably not quite as precise. That probably means that the reading could be a hundredth or two off. I'm not concerned with being that precise in brewing.
What's interesting about the probe on the MW-101 and 102 is that it is a double-junction probe that is therefore a little less prone to fouling. In addition, it uses a gel electrolyte that seems to be fairly stable in my occasional hobbyist usage. When it finally fails, it looks like it will be about $40 shipped to have another.
