Micrometer Screw Gauge.
Micrometers use the principle of a screw to amplify small distances that are too small to measure directly into large rotations of the screw that are big enough to read from a scale. Micrometer screw gauge is another instrument used for measuring accurately the diameter of a thin wire or the thickness of a sheet of metal. The most common Micrometer screw gauge used in education purpose have a maximum lenght of 2.5cm and are accurate up to 0.001cm.
Vernier Caliper.
To Measure Outer and Inner Diameter; Thickness and Depth and Step measuring. Suitable for measuring cylinderical object and / or any object in which total lenght of any of it's dimention less than the maximum lenght of the vernier caliper used. Vernier caliper sold in the markets today come in varius type and sizes. Some have specialised purpose and some are made with dial scale reader or event with digital scale display. The most common vernier caliper used in education purpose have a maximum lenght of 13cm and are accurate up to 0.01cm.
Rulers.
Rulers have long been made of wood in a wide range of sizes. Plastics have been used since they were invented; they can be moulded with length markings instead of being scribed. Metal is used for more durable rulers for use in the workshop; sometimes a metal edge is embedded into a wooden desk ruler to preserve the edge when used for straight-line cutting. There are three type of ruler commonly used in education purpose which are 100cm ruler, 50cm ruler and 30cm ruler. All these types of ruler are accurate up to 0.1cm.
Measuring Tape.
A tape measure or measuring tape is a flexible form of ruler. It consists of a ribbon of cloth, plastic, fiber glass, or metal strip with linear-measurement markings. It is a common measuring tool. Its flexibility allows for a measure of great length to be easily carried in pocket or toolkit and permits one to measure around curves or corners. All these types of ruler are accurate up to 0.1cm.
To Measure Time and Period.
Stopwatch
A stopwatch is a handheld timepiece designed to measure the amount of time elapsed from a particular time when activated to when the piece is deactivated. The timing functions are traditionally controlled by two buttons on the case. Pressing the top button starts the timer running, and pressing the button a second time stops it, leaving the elapsed time displayed. A press of the second button then resets the stopwatch to zero. The most common stopwatch used in education purpose have a maximum period of 1 hour and are accurate up to 1 millisecond.
To Measure Mass and Force.
Dial-O-Gram Balance.
Tripple Beam Balance.
Electronic Weighing Balance / Scale.
Newton Spring Balance.
To Measure a Liquid Volume
Graduated Measuring Cylinder.
A graduated cylinder, also known as a measuring cylinder, is a piece of laboratory equipment used to accurately measure the volume of a liquid. Graduated cylinders are generally more accurate and precise for this purpose than flasks and beakers. Graduated cylinders are made of glasses, polypropylene or polymethylpentene. These materials are excellent chemical resistance and for its clarity.
