Screw Gauge (Micrometer) – 0.01 mm Precision
The Screw Gauge (Micrometer) is a precision measuring instrument used to measure small dimensions such as the diameter of a wire and the thickness of thin sheets. Manufactured by Elmo Agencies, a scientific manufacturer in Ambala, it is suitable for school and college physics laboratories, workshops, and practical measurement applications.
With a least count of 0.01 mm, the screw gauge provides finer measurement resolution than a standard ruler and is commonly used where small dimensions need to be determined accurately.

Key Features
0.01 mm Least Count
The instrument has a 0.01 mm least count, allowing small measurements to be read to a hundredth of a millimetre.
Two Range Options
Available in 0–20 mm and 0–25 mm ranges to accommodate different measurement requirements.
Ratchet Stop & Lock Nut
The ratchet mechanism helps apply consistent measuring pressure, while the lock nut can hold the spindle position during reading.
U-Shaped Frame
The sturdy U-shaped frame provides the basic structure needed for practical laboratory measurements.
Applications
The Screw Gauge (Micrometer) can be used for:
- Measuring the diameter of wires
- Measuring the thickness of metal sheets
- Measuring the thickness of thin materials such as paper
- School and college physics practicals
- Engineering workshop measurements
- Laboratory measurement activities
The measurement is obtained by combining the reading from the main scale with the reading from the circular or thimble scale, using the instrument’s specified least count.

Resonance Apparatus
- The Resonance Apparatus consists of an open-ended cylindrical S.S tube, 1M long and 25 mm dia, mounted on a polished wooden board.
- The tube is sealed tightly at the lower end with a side tube connected to a brass reservoir using rubber tubing.
- The reservoir is mounted on a support, which when raised or lowered, increases or decreases the height of the water column respectively.
- The height of the column is determined by measuring the distance between the zero-stop and the lower end of the tube using the meter scale attached to the apparatus.
