Distance measuring devices used in the field of measurement are as follows:
1 Tape Measure Linen
Measuring tape is made of linen, a width of 2 cm and a length of 10 m, 15 m, 30 m, 50 m .. The weakness of the measuring tape is easily wet when exposed to water, making it easy stretchable / aft and easily damaged / broken. And its use is not using pocket balance. This will lead to less thorough in measuring the distance directly.

Fiberglass Tape Measure 2
The measuring tape is made of fiberglass, a width of 2 cm length of 15m, 30m and 50m. Measuring tape is extremely strong, lightweight and resistant to water, so it is widely used in measurement, both wet areas and dry areas. When its use is not using pocket balance. Note also that when the roll should not be folded.

3. Tape Measure Steel
Measuring tape is made of steel ribbon width of 2 cm, thickness 0.4 mm, and a length of 20 m, 30 m, 50 m and 100 m. This tool uses balance pocket mounted on the end of the measuring tape is pulled 5 to 8 koligram. Noteworthy, the use of these tools should avoid vehicular traffic, because when a steel measuring tape is crushed by the wheels of vehicles as a result can be broken.

4. Chain Measure
The eyes are connected to each other and mounted brass ring for every length of 1 m, 10 m, 20 m, 25 m and 30 m. However, this is rarely sat measuring chain is used, and the use of these tools should use the pocket balance with a maximum tensile force of 10 kg. Natural withdrawal of this measuring chain, should be noted that the chain should not be wrinkled and folded. As a complement, in use in the field, should be provided the steel pen to avoid measurement error.

5. Wheel Measure
This tool is a wheel size of 30 cm s / d 40 cm and is equipped with a plunger rod. Between the wheels are recording distance scale ranging from centimeters, meters and kilometers. This wheel is equipped with a pointing jraum size limit. This tool is widely used in the measurement of the distance highways in the framework of the calculation of the volume of work. Noteworthy, this tool is used in a manner to be driven straight.
