Universal Surface Gauge Manufacturer,Supplier and Exporter in India
Product Code : EL-CLE-9097
Jlab Export is a leading Universal Surface Gauge Manufacturer,and suppliers in India
A surface gauge stands on a surface plate and scribes lines at a set height, or checks that a face is parallel to the plate. This one has a hardened, surface ground steel base with a V-groove and a 250 mm spindle. A scriber clamp holds the scriber, and a spindle clamp locks the spindle.

Workshop Practice: Height Lines and Parallelism
Students set the scriber point to a height on a Steel Rule held upright against an Engineers Square. They lock both clamps and slide the base over the plate to scribe a line round the job. The same line can then be marked with the Vernier Height Gauge, which reads the height on its own vernier scale.
For a parallelism check, the scriber point is set to just touch the top face of a block at one corner. As the gauge is moved to the other corners, any gap or rubbing under the point shows how far the face is out of parallel with the plate.
Frequently Asked Questions
How is a surface gauge different from a height gauge?
A surface gauge has no scale of its own. Its scriber is set to a rule, and the gauge transfers that height to the work. A vernier height gauge reads the height directly, so it measures as well as marks.
What is the V-groove in the base for?
The groove lets the base sit astride a round bar or a curved face. The gauge can then scribe lines along the bar, parallel to its axis.
Why must the base and the work be clean?
Grit or a burr under the base tilts the spindle and moves the scriber point. Wipe the plate, the base and the bottom of the work before setting the height, and file burrs off the job first.
How do I stop the setting from slipping?
Tighten the spindle clamp and the scriber clamp firmly once the point is at the height you want. Check the point against the rule again before scribing, because tightening a clamp can shift it slightly.
