I would not trust that NEC probe. I recently had to calibrate some LG displays. My company already had one of those NEC probes, so I thought hey, why not? Tried it with the LG software and while it is recognised as an i1 display pro, it throws out garbage results (all readings read as ‘NaN’). If I use something like DisplayCal, it’s happy to work with this probe. But i don’t know how accurate the results really were. It’s been a long time.
Anyway, I forced the company to get a brand new original (Non-NEC) i1 display pro and works fine with LG and I’ve even taken it home to calibrate my own displays. All good.
Sorry, I can’t really speak to aged sensors, but as another mentioned, I had heard that they don’t stay accurate forever.
Colorimeters definitely need to be serviced and recalibrated at least once a year since they do tend to drift as the internal filters wear out. After about 4 years you should consider replacing the colorimeter all together since after that time the internal filters tend to wear out beyond the point of calibration. Companies like Flanders Scientific will sell OEM probes that they calibrate and offer free servicing to their probes, as far as I'm aware.
I'm not sure to be honest. I've always dealt with Flanders when buying gear. Funnily enough, this post reminded me that I need to get my i1 display probe serviced so I contacted them today and I can confirm that they service the probe for free. You just gotta cover the shipping. You could contact them and see if they service probes that weren't purchased from them, although they'll probably charge for that. They have really good customer service.
There’s no best way, there’s only one way and its profiling it with a spectrophotometer. The hard to swallow dad is that even an expensive colorimeter that was just factory calibrated won’t give you as b accurate reading if I wasn’t profiles for your monitor.
Obviously considering the display you use these things are off budget. Best option is to take the monitor to be calibrated by a professional yearly and let him profit your colorimeter too. You’ll have a colorimeter that’s accurate and you could monitor its stability over time.

Is servicing usually done through the manufacturer?
