One of the indispensible measuring tools for model building, the digital caliper takes all the guess out of measuring. An accurate measurement can be taken of any part, slot or hole, with fine adjustment by thumbwheel to ensure you have the jaws tight against the edges. The measurement is displayed digitally from a user-setable reference datum. Just read off the exact measurement instead of struggling to count the marks on your rule to the nearest millimeter!
Uses the common SR/CR44 / GP357 button cell battery.
