Does it have to do with accuracy?

The answers you have got here are all right. But I think there is one more thing to it that people tend to forget,
If you need to purchase, say, two thousand scales for a hospital, how many of them do you expect to have left in service after ten years? Nearly all of them.
After 15 years? A bit fewer.
After 20 years? As many as actually works. And you probably have a storage room full of spare parts form slaughtered units that have been recently decommissioned.
After 25 years? Probably still at least a handful.
If old equipment does the job right, there is pretty much no use to replace it just because the newer thing looks cooler.
Once it breaks down for good, it’ll be replaced with what’s considered the standard of today. But as long as it works and you can acquire spare parts to keep it working, you are not going to just throw it away because of *age*.
