It has a stated measuring range of 0-100mm and a card foot of 24mm. The double scale display covers metric and British conversion, so readings can be taken in either format without a separate conversion step. The body is made from all copper using a brass casting process. The push-and-pull buttons are intended to make adjustment simple during repeated measuring. For round objects such as a walnut, the caliper can accurately measure a diameter of 4.8cm. The scale is supplied as one unit in the listed double scale colour and 100mm size option. It suits small-object checking where a clear vernier scale and compact copper body are useful.\u003c\/p\u003e\\n\\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/1802631467137.webp\"\u003e\u003c\/div\u003e\\n\u003cp\u003eThe core construction details come from the source specification: an all-copper body, a brass casting process, and a vernier display. These details matter because they define the tool as a compact measuring instrument rather than a general-purpose ruler. The 0-100mm range and 24mm card foot are the main size references available. The double scale supports metric and British reading. The push-and-pull buttons are the stated adjustment method.\u003c\/p\u003e\\n\\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\\n\u003cp\u003eThe caliper body is made from all copper. The source describes the brass casting process ruler body as strong, stable and durable, with clear scales that are easy to read. These points relate directly to the stated material and construction. The copper body gives the tool its weight and feel, while the casting process forms the ruler body. The double scale vernier display is part of the same build. No other coating, finish, or material composition is stated in the source.\u003c\/p\u003e\\n\\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\\n\u003cp\u003eThe measuring range is 0-100mm, and the card foot is 24mm. These are the only dimensions given for the tool itself. The source also states that the caliper can accurately measure a round object diameter of 4.8cm, using a walnut as an example. That makes the size suitable for small round items rather than large workpieces. The 100mm size option matches the listed range. If you need to check dimensions beyond 100mm, this caliper is not intended for that range.\u003c\/p\u003e\\n\\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/217328923504.webp\"\u003e\u003c\/div\u003e\\n\u003cp\u003eThis caliper is aimed at small-object measuring tasks. The source refers to walnuts, jewellery-type small items, and general portable use through the Wenwan Copper Mini Portable Caliper name. It can be kept on a workbench, in a tool tray, or with craft items. The double scale makes it usable where either metric or British readings are needed. The compact copper body suits handling and storage.\u003c\/p\u003e\\n\\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\\n\u003cp\u003eFor craft, jewellery, and small-component work, the caliper provides a 0-100mm range and a 24mm card foot. The vernier display gives a direct scale reading. The push-and-pull buttons allow adjustment during measuring. The double scale supports metric and British conversion, which is useful when instructions or component lists use different units. The source states high precision and easy use, supported by the clear scales and vernier design. It is not described as a laboratory-grade instrument, so it should be used within the stated range and for the small-object tasks outlined.\u003c\/p\u003e\\n\\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\\n\u003cp\u003eAt home, this mini copper caliper can be used for checking small items such as beads, fittings, or craft parts. The source gives the walnut example, stating that it can accurately measure a diameter of 4.8cm. That makes it relevant for round objects of a similar size. The compact size and simple push-and-pull buttons make it easy to keep with other small tools. The all-copper body and clear scales are the main practical features. It is not a replacement for a larger caliper when measuring beyond the 100mm range.\u003c\/p\u003e\\n\\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/4759435617167.webp\"\u003e\u003c\/div\u003e\\n\u003cp\u003eThe buying value comes from the combination of a 0-100mm range, a 24mm card foot, a double scale display, and an all-copper body. These are concrete features from the source, not added claims. The caliper is built for small-object measuring and can be used repeatedly with the push-and-pull button adjustment. The metric and British conversion avoids manual unit changing. The vernier caliper display gives a clear scale for reading.\u003c\/p\u003e\\n\\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\\n\u003cp\u003eThe copper body and vernier scale are the stated construction points. To keep the scale clear and the movement smooth, keep the tool clean and dry after use. The source does not provide specialist care instructions, so simple cleaning is the safe approach. Store it in a dry place to avoid unnecessary tarnishing or dirt build-up on the scale. With basic handling, the caliper can be kept ready for repeated small measuring tasks. No lifespan or performance guarantee is stated in the source.\u003c\/p\u003e\\n\\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\\n\u003cp\u003eChoose this caliper if you need a compact copper measuring tool with a 0-100mm range and a 24mm card foot. It reads in metric and British units through the double scale vernier display. The push-and-pull buttons make adjustment straightforward. The all-copper body gives it a solid feel. The source specifically notes accurate 4.8cm diameter measurement for round objects such as a walnut. It is supplied as one scale in the double scale colour and 100mm size option.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/6074221832519.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/719790676733.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Mini copper vernier caliper with double scale, 100mm range, and 24mm card foot for small object measuring\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US14\/2294\/2025-10-16\/original-image\/763025977492.webp\"\u003e\u003c\/div\u003e","brand":"u9cmuw-dx","offers":[{"title":"Double scale \/ 100mm","offer_id":57749908193660,"sku":"CJJSBGBG00871-Double scale-100mm","price":19.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/1685\/3628\/files\/763025977492.webp?v=1792458754","url":"https:\/\/havenmere.co.uk\/products\/mini-copper-vernier-caliper-100mm-double-scale-measuring-tool-for-walnut-diameter-jewellery-beads-and-small-craft-components","provider":"Havenmere.co.uk","version":"1.0","type":"link"}
