5. Introduction
 In our daily life, we need to know measurements and dimensions,
especially in the fields of engineering, construction and science.
Measurements are physical values They are: length, width, height,
weight, pressure, current, time, temperature, or force, and it is
measured using a set of tools and machines that we will introduce you
to in this article.
 No one can live alone from the measurements tool because every one
need to use wheatear : the artist need to measure his dimension for his
painting and the different engineer jobs want to dimension the heigh of
and sizes of shapes and the thickness
 In common most people need to use measurement tools and especially
engineers jobs
examples

6. First Tool
 Depth gauges are tools for measuring things such as depth of grooves and height of protrusions.
Numerical measurements are made by vernier. Main scale length is generally 150, 200, or 300 mm.
 We use it for Application for using this tool is to determine if the hole is drilled to the correct required
depth.
 this tools is very important for all engineers and especially civil engineer because when they start to
dig soil for arrive to foundation level this need a tools to measure the depth of hole if it’s the suitable
depth so this can stop soil dig and start to founded the building
Depth Gauge

7. First Tool
Depth Gauge
 This Tool have a many size shapes types so we are going to talk about two basic types of this tools :
Definition of tools :This is, in effect, a dial indicator with a depth base attached. The depth base spans the
opening, keeping the indicator steady and giving you perpendicular entry into the hole, slot or groove.
Advantage :
A- high resolution up to .0001 b- can be used for direct readings or as a quick reading comparator c- easily repaired
Disadvantage
:
A- needs to be carefully adjusted before use because wrong use can lead to wrong measure
b- minimum hole or groove diameter

Dial Depth Gage

8. First Tool
Depth Gauge
Definition of tools The same features as the dial depth gage with the added bonus of quick and accurate
interpretation of the read-out. No skill is needed in interpreting dial hands
.
Additionally, you can switch between inch and metric systems at the touch of a button. Gages with SPC
output can be used where large quantities of measurements are involved and statistical analysis is
required
.
Advantage :
A- easy to read for unskilled users b- faster for large quantities c- easily repaired
Disadvantage
:
A- needs to be carefully adjusted before use because wrong use can lead to wrong measure
b- minimum hole or groove diameter

Digital Depth Gage

9.  If we think for a period of time is the steel ruler that we know
is tool from measurement tools exactly the ruler tool that’s
you thinks that’s the children and student uses it is one of the
measurement tools .
 Steel Rulers are one of the most used tools for measuring
length. Rulers are used to measure lengths accurately,
because they contain measurements drawn on the side,
and may contain measurements on both sides, and they are
used from school students to universities offices and
various projects, especially in engineering, construction,
printing, technical and architectural drawing.
Second Tool
Steel ruler

10. Second Tool
Steel ruler
How We Use steel ruler for measurement jobs
?
The ruler is divided to (m) … ( cm )and (mm) { metric } in
top and {inches} in bottom so that’s make the
Measurement process more accurate but from its
disadvantage that’s it is not to tall so we cant use it Except
in simple operations so we see that’s been used in
education and office works
Inch measure
metric measure

11. 11
Third Tool
Micro meter
 Micrometer is a measurement tools which is characterized by its very
accurate gradation, as it gives measurements to the nearest 0.001 mm, and
it is a very accurate tool used in laboratories and scientific laboratories.
 There is a different sizes and shapes that’s we can see such as :
1- outside micrometer 2- inside micrometer 3- Depth micrometer

12. 12
Third Tool
Micro meter
Depth micrometer
This type makes accurate
depth measurement of
holes or cavities.
 Measures the distance
from the center of the
crankshaft to the top of
engine block
 Measures the distance
from the top of the
piston to the top of the
engine block.
Some properties for each type of micrometer
Outside micrometer
Used when outside
measurement is accurate to
0.01 in or less
Inside micrometer
Used when a measurement
of a hole’s diameter is
accurate to less than 0.01 in
Examples of holes:
Cylinder, bores and the
main bearing bores.

forth Tool
Calipers
 A caliper is a measuring tool or device that consists of two adjustable legs or jaws for measuring the distance
between two opposite sides of an object. Calipers are often employed for measuring thicknesses and internal or
external diameters inaccessible to a scale.
 Calipers can be used to take measurements of outside size, inside size, depth, and step. Outside calipers measure the
thickness and outside diameters, inside calipers measure hole diameters and distances between surfaces. Calipers
are often used for precise measurement in scientific labs and engineering schools

14. 14
forth Tool
Some types of calipers
Inside Caliper
are used to measure the
internal size of an object
outside Caliper
are used to measure the
external size of an object
Divider caliper
sometimes is referred to as
compass, used to mark out
locations
Vernier caliper
We will talk about
later
in separately

15. 15
forth Tool
Some types of calipers
Dial caliper
the dial caliper reads the result (fraction of a millimeter or inch)
on a simple dial .The dial is generally designed to be rotary for
the measuring of the difference in size between two objects
Digital Caliper
What makes a digital caliper differ from a dial and
vernier caliper is that it uses an electronic display to
replace the dial or vernier scale, to show the reading
as a numeric value. Digital calipers use a linear
encoder

16. 16
Vernier calliper is one of the measurement tools that’s we use it for measure its very necessary
for engineers they called it the smart engineer tools especially civil engineer because they use it
for determine the Reinforcement diameter and Screw diameter especially metal structures
where the engineers need it very much
Fifth Tool
Vernier calliper

17. 17
Vernier calliper
a measuring device that consists of a main scale with a fixed jaw and a sliding jaw
with an attached vernier
.
Advantage
:
What it consists from
it’s essentially for accuracy. It has the normal larger
scale but also a scale within that main scale that
allows for clearer resolution and accuracy, which
removes any potential of human error.

18. 18
 Height gauges are precision measuring instruments that can be used
to determine the height of an object or workpiece with extremely
high precision and accuracy, or to provide marked locations on the
item relative to a reference plane for subsequent us
 A height gauge is a precision instrument used to measure the depth
of holes, the height of work, recesses, slots, and steps with an
accuracy of 0.02 mm.
Last Tool
Heigh Gauge

19. 19
Last Tool+ conclusion
Heigh Gauge
 Height gauges may be broadly characterized into four basic types: Vernier height gauges. Dial
height gauges. Digital counter height gauges.
conclusion
 Measurement tools are very necessary for any work you want to do when you want to take a
accurate work whether in demission or tall are size you need to measure the parts and that dine
by measurement because some engineer works in common and structure works especially need
accurate in work because any mistake maybe It may lead to job disqualification
