A measuring instrument is a tool used to measure a magnitude or dimension in physics. In general, there are three most measured magnitudes in the world of physics for high school level namely length, mass and time and dimension. Various measuring instruments of length, mass and time can be seen as follows:

Long Measuring Instruments

Long measuring instruments include mistar, long Bow, and micrometer skrup. Here are each of these dimension measuring instruments & explanations.

Mistar/Ruler

Mistar, otherwise known as a ruler, is a tool used to measure the dimensions of medium and large items.

Mistar

This mistar function can measure with precision up to 1 mm. A long gauge widely used in daily life is mistar. The smallest scale of the mistar is 1 mm (0.1 cm) and its precision is half the smallest scale of 0.5 mm (0.05 cm).

Bow

in practice, measuring long dimensions sometimes requires a measuring instrument capable of reading measuring results up to 0.1 mm (0.01 cm) accuracy. For this kind of measurement we can use a long-term shove.

Sorong Bow

A srong Bow is a tool used to measure the diameter, the measuring instrument of the outer dimensions of an object, and the dimensions in an object.

This measuring instrument has 2 parts, namely a fixed jaw whose function as a fixed scale place is non-movable, and a hollow jaw that functions as a nonius scale place and can be shifted to adjust and measure objects. This measuring instrument can measure with precision up to 0.1 mm.

Skrup Micrometer

Micrometer skrup measuring instrument is a tool used to measure the thickness of a thin object, the length of a small object, and the outer dimensions of a small object.

Skrup Micrometer

This dimensional measuring instrument has 3 parts, namely the main sheath whose function as the main scale place will show how much the measurement results and this part is fixed and can not be shifted, then the outer sheath whose function as a nonius scale that can be rotated to move the thread casing so that it can adjust to the measured object shape, and the thread casing whose function as a part that can be moved by rotating the outer casing so that it can adjust to the shape of the measured object. These micrometers can measure with precision up to 0.01 mm.

Mass Measuring Instruments

There is only one type of mass measuring instrument, namely the balance sheet. Even so, the balance sheet is actually various. Here’s an explanation.

Mass Measuring Instruments

Balance sheets, otherwise known as scales, are tools used to measure the mass of an object. There are several types of balance sheets, namely

Market Balance, which is a balance sheet commonly used in traditional markets, the shape as in the picture on the side. The way to use this balance sheet is to place the object to be weighed in a basin-shaped section, then on the side of it is a flat sheet that is almost balanced with the weight of the object, then the balance sheet arm will move and the measurement results can be known.

Two-Arm Balance,which is a balance sheet that is usually found in the laboratory, is shaped as in the picture on the side. The way this balance sheet is used is almost the same as the way the market balance is used, the difference between the balance sheet on the market balance sheet can be replaced with other goods.

Three Arms Balance,which is a balance sheet that is also usually found in the laboratory, is shaped as in the picture on the side. The way this balance sheet is used is by sliding the three pointers to the far left side (the scale is zero), then place the object to be measured on the left where there is a place for the object to be measured, then slide the three pointers to the right until the balance appears, and the measurement results can be known.

Bathroom Balance,is a balance sheet commonly used to measure weight, its shape as in the image on the side. These balance sheets are usually found in clinics, hospitals, homes, or perhaps in other places that have these balance sheets. The way this balance sheet is used is by the way we rise to the top of this balance sheet, then the needle contained in the balance sheet will show how much our weight measurement results.

Timer dimensions

Time is the interval between two events. For example, the time of day is from sunrise to sunset, the time of life is from birth to death.

Time Measuring Instruments
Time Measuring Instruments

For event events that lapse to occur long enough, time is expressed in larger units, e.g. minutes, hours, days, months, years, centuries and others.

  • 1 day = 24 hours
  • 1 hour = 60 minutes
  • 1 minute = 60 seconds

Meanwhile, for rapid events, it can be used as a millisecon (ms) and microsecs (μs) units. For daily use, time gauges have been made, such as stopwatches and watches
