Since they don't say, it seems that it is "digital" in that respect, meaning it either works per the spec or it doesn't work at all, not that it can drift over time. It seems like a quality product, and I'd expect it to last 5 years of continuous use, but the warranty is 2 years, and the "service life characteristics" are available on request, so why not request them.
