This simple measuring tool, also known as a vernier calliper, is handy to keep at home when an ordinary ruler is not enough. It can measure the external diameter, internal diameter, thickness, length and depth of objects up to 155 mm.
The tool is especially useful when buying a spare part or accessory and the product description specifies a particular measurement. Measure openings, pipes, plugs, caps and other small parts at home, then compare the result with the dimensions on the product page. This makes it easier to choose the right item and reduces the risk of ordering the wrong size.
The calliper is made from plastic, which reduces the risk of scratching the item being measured. The scale shows both millimetres and inches and is suitable for practical measurements around the home.
External measurements: Place the larger jaws around the object and gently slide them together.
Internal measurements: Insert the smaller upper jaws into the opening and move them apart until they touch both sides.
Depth: Place the end of the calliper against the opening and extend the depth rod until it reaches the bottom.
Keep the tool straight and allow the jaws to rest lightly against the object before reading the measurement on the scale.
