I bought a set of these woodworker measuring block sets a while back. It cost me $31 at the Jungle.
it has 7 pieces plus a case. Each block has a width, a bridge, and a couple of tabs of the specified dimension. To aid in setting bit height, fence Clearances and gaps. Long enough to bridge bits and blades to check height. More flexible than plain old set up bars of which I have sets as well.
made of anodized aluminum in red (or other colors) with sharp easy to read white inked markings. Fairly durable so far, not scraped by router bits.
Also has some reference angles on the end which I have not yet had the occasion to use.
it's not the cheapest thing around but not all that expensive and I enjoyed using mine around the router a bunch so far.
not more than twice the cost of a precision setup bar set.


One way I use this is to set the bridge over the lowerd router bit tip. then i raise the bit until i see a hair of movement between the gauge and the table, then i back off a hair and repeat until it just moves, then I know the bit height is exactly that height. Much easier than using a bar and a straight edge! The tab on the end is a quick check for groove depth.
