Digital Caliper

The post was published in blogs iXBT.com, its author is not related to the editorial office of iXBT.com It's already the 21st century, and the idea came to me to replace my old caliper, which I got from my grandfather, and my grandfather - from my great-grandfather ☺, with something more modern; sort of electronic and digital. And so a shiny new electronic caliper from the Middle Kingdom ended up in my hands. The characteristics are taken from the short instructions supplied with the caliper: External dimensions, internal dimensions, depth, size difference Maximum permissible frame speed Unlike conventional vernier calipers, here it is possible to measure the difference in dimensions (carried out using the zeroing button after the first measurement). The total can be either positive or negative (the device shows a minus sign). The price for Aliexpress at the date of the review is about 970 Russian rubles ($ 12.8) complete with a case CHECK THE CURRENT PRICE OR BUY. Almost complete analogs of this electronic caliper can be found in Russian stores using t Digital Caliper he Yandex.Market price comparison service. Prices vary widely, from about 1000 to 2000 Russian rubles, CHECK THE CURRENT PRICES OR BUY. Due to higher prices, stores with Yandex.Market may be of greater interest to legal entities rather than individuals. The caliper came in a sturdy plastic case with two latches that securely hold its sash: If you look closely at the photograph, in the lower right corner of the case you can see a recess for a nameplate, which can be glued by some virtual "manufacturers" and declare that it seems like they made the device. :) In this case, there is no nameplate, and the device is sold without identification marks, as it came from a real contract manufacturer; which allows you to reduce the price by a few cents. In the case, in addition to the caliper packed in a trapezoidal plastic bag, there is a brief instruction manual: Important note: the LR44 battery required for the operation of the device is not included in the package, you will have to buy it separately, you can also go to Aliexpress, LINK. Price - $ 1.10 for a dozen (!). https://jiji.ng/wuse/measuring-and-layout-tools/digital-caliper-fjxeFVOnBnaxhNQGUDRQqYm2.html
