Does what it is supposed to do. Accurate.

Does what it is supposed to do. Accurate.
This is spot on dead accurate, so it does what it's supposed to do, however it came a little dinged up. Not a good sign when this is supposed to be tool to benchmark accuracy against. Nonetheless, it works!

    It measured fat on my calipers and mic by .0001 inch, plenty accurate for the work I'm doing. It's good to have and the price is right.

    These gages are useful when double checking measurement devides.

    I tried this against three calipers: a Mitotoyu and a couple of Chinese knockoffs. They all read 25.00mm. Not too shabby.

    Measured this with a calibrated Mitutoyo Digimatic caliper and it measured 25.00 mm. I don't have the capability to measure it any more accurately. I wish it came with a certificate of accuracy or even had a specification listed, but it's cheap enough.

    I was prompted by Amazon to review this item.
    I got this standard rod to check a new digit caliper.
    I measured a minimal deviation from the 25mm reference length (25.01mm). Is the rod correct with a caliper error? Is the caliper correct, but this rod is slightly off? I do not know, but at least I can believe both are close enough for what I need.
    So YES, this is a decent tool to around in case I drop my calipers & need to know if they still work.
