Dial Gauge Manufacturer,Supplier and Exporter in India
Product Code : EL-CLE-9105
Jlab Export is a leading Dial Gauge Manufacturer,and suppliers in India
A dial gauge turns small movements of its plunger into pointer readings, so fitters and students can check run-out, flatness and alignment. This gauge has a 10 mm range, 0.01 mm graduations and a 0-50-0 dial of about 60 mm diameter. It is held on a switchable magnetic base and comes with brackets, attachments and a fitted case.

How the Dial Gauge Is Read
The plunger carries a rack that turns a pinion, and gearing passes the movement on to the pointer. Each small division is 0.01 mm. The dial is numbered from 0 to 50 in both directions from zero, so one turn of the pointer equals 1 mm of plunger travel. The balanced dial lets students read deviations either side of a zero set on the work.
Workshop Practice: Run-Out and Parallelism Checks
To check run-out, students mount a turned shaft between centres. They set the magnetic base on a steel surface and bring the contact point onto the shaft with a little preload. They zero the bezel, turn the shaft slowly by hand and note the highest and lowest readings. The difference is the total indicated run-out. The shaft diameter can be measured first with an External Micrometer.
For parallelism, a block is set on a surface plate and the gauge is swept across its top face. Students then measure the same face at several points with the Vernier Height Gauge and compare the two methods. In a theory of machines lab, the same kind of gauge reads follower lift on the Cam and Follower Apparatus as each cam is turned by hand.
Frequently Asked Questions
What is the smallest reading on this dial gauge?
It is 0.01 mm, the value of one division on the dial. The gauge reads over a 10 mm range, and with its 0-50-0 dial the pointer makes one full turn for every 1 mm of plunger movement.
How do I set the zero?
Bring the contact point onto the work so the plunger is pushed in a little, then lock the base. Turn the bezel until the zero line sits under the pointer. Dial and bezel rotate through 360 degrees, so zero can be set wherever the pointer stops.
How does the magnetic base switch on and off?
It has a permanent magnet worked by a push button. With the magnet on, any of the three energised sides holds to a steel surface. Switch it off to lift the base clear or slide it to a new position.
Should I choose a plunger dial gauge or a lever-type test indicator?
A plunger gauge like this one moves in line with its spindle and has a long range, here 10 mm. A lever-type test indicator has a short swinging stylus for tight spaces. For shaft run-out and flatness on blocks, the plunger type is the usual choice.
