The Micrometer Screw Gauge AGN-112 from AGN Enterprises is a precision mechanical measuring instrument designed for measuring small dimensions such as the diameter of wires, thickness of sheets, and dimensions of small cylindrical or spherical objects. AGN Enterprises lists micrometer screw gauges within its Physics Laboratory equipment range.
A micrometer screw gauge works on the screw principle, converting rotational movement of the thimble into precise linear movement of the spindle. This allows measurements smaller than those normally obtained with a standard ruler and is widely used in physics and mechanical measurement practicals.
The Micrometer Screw Gauge AGN-112 operates using an accurately manufactured screw mechanism. When the thimble is rotated, the spindle moves toward or away from the fixed anvil.
The instrument generally incorporates a main/pitch scale and circular or thimble scale. The screw’s pitch determines the distance the spindle travels during one complete revolution, while the divisions on the circular scale enable smaller measurements to be read.
The measurement is obtained by combining the main-scale reading with the appropriate circular-scale reading and applying any required zero correction.
The instrument can be used for:
A micrometer screw gauge is particularly useful when the dimension being measured is too small for convenient measurement with a conventional scale.
The AGN-112 Micrometer Screw Gauge can help students learn important concepts related to precision measurement, including:
Students can use the instrument to take repeated measurements and calculate average values, helping them develop practical measurement and laboratory-recording skills.
The instrument can be incorporated into experiments such as:
For example, once the diameter of a wire has been measured, students can use that measurement in subsequent physics calculations involving its cross-sectional area or other physical properties.
Compared with ordinary measuring scales, a micrometer screw gauge provides a much finer measurement capability. Its screw mechanism enables controlled movement of the spindle, while the graduated scales allow small dimensional changes to be read.
Consequently, it is a valuable instrument for teaching students how precision measurement differs from ordinary length measurement.
The Micrometer Screw Gauge AGN-112 is suitable for:
AGN Enterprises identifies micrometer screw gauges as part of its Physics Laboratory equipment range.
Before procurement, users should confirm the exact measurement range, least count, scale graduation, construction material, accuracy, and supplied accessories for AGN-112, since these specifications are not stated on the publicly indexed AGN Enterprises category page.
