About Measuring Tools
Measuring tools are used to determine dimensions such as length, width, thickness, and diameter with accuracy. They are essential in engineering and workshop tasks. Examples include rulers, calipers, micrometers, and measuring tapes.
Dial Indicator
A Dial Indicator is a precision measuring instrument used to measure small linear distances and deviations with high accuracy. It converts small mechanical movements into readable values on a dial face. This tool is widely used in fitting, machining, and quality control to check alignment, run-out, and surface variations.
Feeler Gauge
Vernier Caliper
A Vernier Caliper is a precision measuring instrument used to measure internal dimensions, external dimensions, and depth with high accuracy. It consists of a main scale and a sliding vernier scale that allows readings up to fractions of a millimeter. This tool is widely used in fitting, machining, and quality control work.
Plumb Bob
Straight Edge
A Straight Edge is a precision measuring instrument used to check the straightness and flatness of surfaces. It is a simple tool with a perfectly straight edge that serves as a reference for inspection and layout work. This tool is widely used in fitting, machining, and quality control applications.
Thickness Feeler Strip
Electronic Vernier Caliper
Gear Tooth Vernier Caliper
A gear tooth vernier caliper is a precision measuring instrument used to measure the thickness of gear teeth at the pitch line. It is specially designed with two scales—one for measuring chordal thickness and another for measuring the depth of the tooth. This tool is widely used in gear manufacturing, inspection, and maintenance to ensure accurate gear dimensions and proper meshing of gears.
