Pinpoint probes should be replaced every 18 months according to the company....

Haha,well they can last from the minute you open them(some are bad right out of the box) til 5 or more years.I think if you get a good one,one that never dried out and was made correctly you can get a good usage life out of it.The best are the lab grade probes but even those will have mixed reviews.

Only tip I can offer is if u buy a probe that is fairly new production(not old stock) even the non lab grade will work fine and last years.Old stock or units that have a poor packing system(allow tip of probe to dry out) will be historically undependable and fail in a hurry.Try to buy probes from a source that sells many so the stock is new and you will have a better chance in getting a good unit.

Super Human Probe....
I purchased a probe back in 2006. Used it a year and broke down my system in 2007. I put the probe in a cup of water so it stays wet while I decided what to do about it. A year later while cleaning the garage I found it again dried up, no water. I figured dead, so I threw it in a HD bucket and went about life.
Onto my recent setup....
Started back up 4 years later in Jan 2011. While setting up I found this PH probe and a ORP probe just sitting in the bottom of a bucket. Well, dried up dead I thought. I read on RC if you can get them wet again, so for 6 months they sat in my tank wet. 1 month ago I connected them to PH monitor with a 5 year old duracell 9v battery, it too was alive, and calibrated to 4.0 and 7.0 solution. Waited for 3 weeks and went to calibrate again, DEAD ON!!!! 3-4 years it was dried out and it came back to life.
Only way to tell is if is bad is it won't calibrate. Tell this to Stan Lee.

+1 => I had the same experience with pinpoint probes, but mostly positive i.e., the work a long time.

it is electrical charge going out of your water and giving feedback to the monitor. I spoke with the folks at Milwaukee about this and they said it will also ruin the probe and possibly the meter.
But grounding your tank comes with a bunch of interesting arguments with it. I will let that up to the experts... but i would also recommend searching the hundreds of discussions on RC about stray current, grounding, etc.
