Screw Gauge Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12109
Jlab Export is a leading Screw Gauge Manufacturer,and suppliers in India
Screw Gauge (code EL-PL-12109) is a micrometer screw gauge for outside measurements from 0 to 25 mm, reading to 0.01 mm, used to find the diameter of wires and the thickness of sheets and glass slips. Its nickel-plated brass frame carries a stainless steel spindle with a ratchet top and a lock. JLab manufactures the JL211/05 gauge in Ambala, India, and packs it in a plastic case.

Reading the Gauge
Turn the ratchet until it slips with the spindle resting on the anvil, and check the circular-scale zero against the reference line; any offset is the zero error. Place the wire between anvil and spindle, close the gap with the ratchet so the measuring pressure is the same each time, and lock the spindle. The reading is the linear-scale value plus the coinciding circular-scale division times the least count, corrected for zero error. Always close the screw in the same direction, so that backlash in the thread does not enter the result.
Where the Least Count Comes From
One full turn of the thimble moves the spindle by the pitch of the screw. Dividing that pitch by the number of circular-scale divisions gives the least count of 0.01 mm, one hundredth of a millimetre.
