Hello,
this meter keeps its vaule very well and is being produced at least 20 years. My question is - what is the liftime of such a device? What maintenence is needed (if some) - calibrations?
I might be thinking of getting one in the run of next few month and 250 euro (~ $320) is the very minimum. New goes for $450 in US and ~ 600 ! euro here in Germany.
So - how much sense it makes to pay $300 for a 10 - 20 years old one .. ?
And - is there any info on serial numbers versus age ?
thanks
