Työntömittoja

Työntömittoja, commonly known as calipers in English, are precision measuring instruments used to determine the dimensions of an object. They are characterized by a pair of jaws that can be opened or closed to fit around or against the surface of the object being measured. The distance between the jaws is then read off a scale, typically on a sliding ruler or a digital display.

There are several types of työntömittoja, including vernier calipers, dial calipers, and digital calipers. Vernier calipers utilize a sliding vernier scale to achieve high precision. Dial calipers employ a dial indicator for a clear visual reading of measurements. Digital calipers offer the most convenience with an electronic display that shows the measurement in numerical form, often with the ability to switch between metric and imperial units.

Työntömittoja are widely used in various fields, including manufacturing, machining, engineering, woodworking, and metalworking. They are essential for ensuring accuracy and consistency in production processes. Their versatility allows for the measurement of external dimensions (using the outer jaws), internal dimensions (using the inner jaws), and depth (using a depth rod). The precision of työntömittoja makes them indispensable tools for quality control and detailed craftsmanship.
