Description

The Brown & Sharpe TESA 05.30021 4-Piece Measuring Set includes a 0 to 25mm external micrometer, 0 to 150mm dial calipers, and a depth measuring base for making precision measurements. The TESAMaster micrometer has a vernier scale with a resolution of 0.001mm and a digital counter with a resolution of 0.1mm, meets DIN (Deutsches Institut für Normung) 863 T1 NF E 11-095, and comes with an inspection report with a declaration of conformity. It has tungsten-carbide-tipped measuring faces and a nut for locking the spindle in place. The TESA CCMA-M dial calipers have a 1.25″ diameter dial indicator with a resolution of 0.02mm and meet DIN 862 (Style 1AR). The calipers are made of hardened stainless steel and have a knurled screw for locking the jaws in place. The depth measuring base is a T-bar style base that attaches to the dial calipers’ blade for measuring holes and recesses. It is 75mm (3″) long. The set comes with a storage case that has molded insert for holding each instrument. Calipers and micrometers are typically used in manufacturing, machining, and mechanical engineering.

Micrometers are precision measuring instruments that use a calibrated screw to measure distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.

Dial calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. A pair of jaws attached to a long beam with a marked scale is used to measure inside, outside, and step measurements in standard or metric units. An additional depth probe slides along the beam to take depth measurements. One jaw is fixed to the end of the scale, while the other jaw slides along it to take measurements. A circular dial indicator is fixed to the movable jaw on a toothed gear rack that transfers movement of the jaws to the dial needle. The base measurement is taken from the long beam, which provides the initial whole measurement in inches or centimeters, and added to the dial reading, which provides fractional measurements in inches or millimeters. A locking mechanism provides the ability to take differential measurements for determining the difference in measurements between two objects. Compared to digital calipers, dial calipers are more durable, but are more susceptible to shock damage and prone to getting dirt in the gears, which can cause accuracy problems. Vernier calipers are more durable than dial calipers because they do not have internal moving parts, but they can be more difficult to read. Dial calipers are commonly used in fields such as metalworking, mechanical engineering, machining, and carpentry.
