The inch and metric measuring rods shown below are designed for calibrating or zero-setting large outside micrometers and calipers of all sizes. It eliminates the need to wring many gage blocks together, a tricky and risky undertaking.
This photo shows a 3" measuring rod being used to calibrate an Etalon vernier caliper. Handle the measuring rods by the plastic heat shields. This prevents the metal from expanding unnecessarily.
The manufacturing accuracy shown below assures you that these standards are perfectly suitable for any .001" measuring micrometer or dial calipers.

What's the rush?
We know that you are in a hurry and need a measuring rod yesterday, but please take three minutes to read the following article carefully. It may end up saving you time.
Many people are looking for rods that are calibrated and can be delivered overnight because an inspector is coming the day after tomorrow. This is a regular and unrealistic scenario. Measuring rods with current calibration certificates are not something you can buy off the shelf and have delivered next day. Even with expedited calibration services, you will have to allow 4-5 days once you have the measuring rod in your hands.
There are many accredited laboratories throughout the U.S. that can calibrate and certify these rods. If there's one nearby, you can deliver and pick up in person in order to save a couple of days in shipping. Since the rods on this page are made by Mitutoyo, you may want to send them to the Mitutoyo Calibration Lab. Call them and see what their overnight calibration service would cost and whether you can have the rods in house before that inspector arrives.
We repeat: Certificate of Calibration is not included and not available from us. The manufacturer guarantees accuracy as stated below. If you need verification in the form of a certificate, you will have to send the rods to an accredited calibration laboratory of your choice.
We have done some of the leg work for you by checking availability and part numbers for measuring rods which are normally in stock online. To make sure that you are getting the genuine manufacturer's product, only buy from reputable and authorized distributors. If buying from Amazon, we suggest you look for the key words: "Ships from and sold by Amazon.com"
