Measurement Tools

Stainless Steel Scale (30cm)

A measuring tape is a flexible tool used for measuring length.
It is made up of materials like fiberglass, cloth, plastic, metal ribbon or strip. So, it is a kind of flexible ruler also known as a tape measure.

Digital calipers may contain a "reading hold" feature, allowing the reading of dimensions after use in awkward locations where the display cannot be seen.
Digital Calipers utilise an LCD display to provide measurements far more accurate than vernier or dial calipers can produce.
Ordinary 6-inch (150 mm) digital calipers are made of stainless steel, have a rated accuracy of 0.001 in (0.02 mm) and a resolution of 0.0005 in (0.01 mm).

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).
It is a standard diagnostic tool for technicians in the electrical/electronic industries.
Multimeters measure resistance by injecting a small current into the circuit, and then measuring the voltage drop across those points in the circuit.

Digital pen electric tester is a non-contact tester pen which provides simple, accurate testing for the presence of voltage, without the complications of more detailed multimeters, clamp meters etc.
Shove the tip into the slots of a receptacle that's live, hold it near a plugged-in lamp cord or hold it against a light bulb that's on.

By connecting probes to different points in a circuit, oscilloscopes can display and measure voltage waveforms, analyze signal integrity, debug circuit problems, and analyze signal frequency and phase.
They are most recognizable for their use in medical settings as a diagnostic tool to measure heartbeats or brainwaves.
Oscilloscopes are also used to analyze various signals (e.g., electric, television, etc.), which is mainly used by engineers or electric technicians.

A Spirit Level is a tool used to indicate how parallel (level) or perpendicular (plumb) a surface is relative to the earth.
A spirit level gets its name from the mineral spirit solution inside the levels.

A cutting mat protects your work surface so that it does not receive any marks from the rotary cutter's blade.
It also prolongs the life of the blade by keeping it from becoming dull.
Many cutting mats also have grid lines or rulers, which helps you to measure as you cut.

A telescope is a device which is used to view far off objects. It is made of a combination of lenses, mirrors or both.
Most telescopes, and all large telescopes, work by using curved mirrors to gather and focus light from the night sky.
The first telescopes focused light by using pieces of curved, clear glass, called lenses.

Foldscope™ is a low cost, paper microscope that can help to magnify beyond the ability of unaided eye and explore our surroundings at the microscopic level.
It is well suited to be used as a teaching and learning aide in Under-resourced regions.
Once assembled, the Foldscope is about the size of a bookmark.
