Hi Steve,
Yes I use one of these at work, not that particular example as I took that off the internet as were not allowed to photograph anything privately in the toolroom. It's made by Mitutoyo and called a coordinate measuring machine, in a temperature controlled environment it will accurately measure to five place a decimal manually or automatically.
I also have a Tessa microscope driven by computer that enables me to measure and photograph components under magnification.
I still have a big hammer.
