Precise measurement is the be-all and end-all of almost every do-it-yourself job. We show, with which measuring tools this works best.
Different accuracies are required for the different work areas. In the garden area are centimeters, in timber construction millimeters and in metal construction at least V10 millimeters is the standard. The measuring tools also differ accordingly.
Rollbandmaße
Tape measures are the ideal complement to rigid measuring sticks. They are usually longer and, since flexible, can be used, for example, when measuring curves. The band is made of corrugated sheet steel, that is painted or plastic coated. The curvature makes the tape stable when extended. There is a hook at the beginning of the band, which can be moved. This evens out the difference between applying tension or compression. The rolled tape is in a cassette and is drawn in again by a spring.
For removing intermediate measurements (light dimensions) some models also have a reading window. Special models are waiting next to the millimeter- and centimeter scale with an additional inch scale.
Tape measures for outside
The tape measures for outdoors are much longer but also more robust. The measuring tape is made of either painted or coated sheet steel (to 100 m Length) or from a glass fiber fabric (to 50 m). The fabric tape is very flexible and quite insensitive. The steel band is not curved and therefore has no intrinsic stability. There is a strong eyelet or loop at the beginning of the tape for pulling and tightening the measuring tape.
Typical measurements in the garden are determining or checking a right angle after the 3:4:5-procedure (s. S. 53) or by comparing the two diagonals of a rectangular area (s. above). When creating garden paths or beds, a tape measure is essential. The tape measures are largely rainproof.
standards
The classic among manual length measuring devices- and handyman is the folding rule, sometimes also called folding rule or meter rule. Formerly mostly made of wood, there are folding rules today made of metal or unbreakable plastic, and in lengths
callipers
If exact values are to be determined (for example in metalworking), is a caliper (or vernier calipers) the right gauge. The workpiece is clamped between the two measuring jaws and the measurement can be taken – depending on the model-on 0,05 mm accurate on the simple scale, on 0,02 mm at the clock as well as on 0,01 mm can be read off the digital display. Calipers are also for internal measurements such as pipes and for depth measurements, for example in blind holes, usable.
Micrometer
The micrometer or outside micrometer is a precision measuring tool, which should be treated with due care. With an accuracy of 1/100 mm, the thicknesses of, for example, wooden materials, Glass, Measure plexiglass. The micrometer has a fine thread, the two measuring surfaces with every 360° rotation 1 mm moved – apart or to each other. The drum has a scale with 100 tick marks, each making up Vioo mm. So the pressure, exerted by the measuring surfaces on the workpiece, is always the same, there is a slipping clutch in the handle of the screw.
depth gauge
The device has the same function, like the additional device on the caliper.
Dickenmesser
Material thicknesses up to 20 The practical thickness gauge measures mm quickly and precisely, which resembles a normal pair of pliers. A spring always presses the measuring jaws together with the same amount of force. All measurements therefore take place under identical conditions. The measured value can then be read off a spread scale with an accuracy of 1/4 mm.
