Product Code : SCL-PLE-14614
Indian Lab Suppliers supplies the Screw Gauge (Micrometer) (Product ID: 14614) as part of its physics lab equipment range. It is a micrometer screw gauge for measuring wire diameters, sheet thickness and other small dimensions.
Quick Answer
The standard model measures 0 to 25 mm with a least count of 0.01 mm; 25–50 mm and 50–75 mm ranges and 0.001 mm models are also available. The least count equals the screw pitch divided by the number of thimble divisions, and a reading is the sleeve (main scale) value plus the thimble value, corrected for any zero error. A ratchet stop applies the same measuring pressure every time, and a locking lever holds the spindle. The spindle and anvil are hardened steel, the body is stainless or alloy steel with a satin chrome anti-glare finish, and stated accuracy is ±0.002 mm.

Frequently Asked Questions
What is the least count?
0.01 mm as standard; 0.001 mm models are available.
What does the ratchet do?
It applies the same measuring pressure each time.
How is zero error handled?
Note the reading with the faces closed and subtract it from each measurement.
