The Starrett 125 series vernier caliper measures in inches and metric, has a 0.001"/0.02mm graduation, and four-way jaws for measuring the inside diameter (ID) and outside diameter (OD) of holes, grooves, and tube thicknesses, and depth and step measurements of bores and grooves. The inch scale on the caliper has an accuracy of + or - 0.001" on 0-4" measurements and + or - 0.0015" on measurements over 4"; the metric scale on the caliper has an accuracy of + or - 0.025mm for each 300mm. Sharp black graduations on a satin-finished bar ease reading. A fine-adjustment screw ensures accurate measurements and a locking screw secures the measurement tightly in place for accurate readings. The hardened stainless steel depth rod is durable and wear-resistant. The caliper includes a fitted case.
Vernier calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. A pair of jaws attached to a long beam with a marked scale is used to take inside, outside, and step measurements. An additional depth probe slides along the beam to take depth measurements. One jaw is fixed to the end of the scale, while the other jaw slides along it with gearless precision to take measurements. The main scale is engraved directly on the beam while the vernier scale is engraved on the slider mechanism. The base measurement is taken from the long beam, which provides the initial whole measurement in inches, centimeters, or millimeters. To obtain the total measurement, the base reading is added to the vernier scale reading, which provides fractional measurements in inches or millimeters. A locking mechanism provides the ability to take differential measurements for determining the difference in measurements between two objects. Compared to digital and dial calipers, vernier calipers are more durable because they do not have internal moving parts, and are less prone to inaccuracy caused by shock, debris, and other contaminants, but they can be more difficult to read than digital and dial calipers. Vernier calipers are commonly used in fields such as metalworking, mechanical engineering, machining, and carpentry.
The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.

Top Customer Reviews
Out of the box: The packaging clearly states that my 125MEA-8/200 was made in China. Although packaged well, I was quite disappointed that the action was a little gritty. They could have done a better job cleaning it before final assembly and oiling. I had to clean and re-oil it - that's a disappointment at this price point although it doesn't affect the functionality. The thumb wheel is not actually a wheel, rather a knurled grip. The plastic storage box is suitable and appears durable.
Fit and Finish: The markings are clear and easy to read -- they appear durable and will not disappear or fade over time. The action is smooth so it's well machined but the overall appearance isn't that great. I would expect that saving all that labor money, they could spend a little extra time polishing.
Other thoughts: It's not a big secret that you can do a lot better on the used market buying older made in the USA tools if you're patient and don't mind a little risk. If you don't have the time or appetite for the risk and you need accurate measurements the 125MEA-8/200 will get the job done.
1. Hardened, good-quality stainless steel construction.
2. Etched markings to ensure durability.
3. Incredibly accurate and precise w/ certificate of calibration.
4. Acceptable quality plastic case w/ padding. This protects the caliper well.
5. Easy to read assuming you have good vision and an attention to detail.
1. The depth measurement tool is confusing at first, but easy enough to use.
2. The locking screw is inadequate unless treated very gently.
3. The way the inches side is divided is a little strange, and it takes some getting used to in order to read it correctly.
4. The difficulty in using the inside calipers to measure diameter is more pronounced in this caliper than others I have used.
5. Probably made in China.
This caliper is a high-quality measuring tool. Considering the larger than normal size (8" as opposed to 6") and incredible accuracy and precision, I feel this is an excellent buy. The price seems fair, but should probably be $20-$30 lower assuming it was not made in the USA.
