Semi Circular Meter Scale Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12249
Jlab Export is a leading Semi Circular Meter Scale Manufacturer,and suppliers in India
Semi Circular Meter Scale (code EL-PL-12249) is a steel protractor with etched graduations from 0° to 180° numbered in both directions, plus a depth gauge scale for measuring depth. The double numbering lets an angle be read from whichever side the baseline lies, without turning the scale round. It is manufactured by JLab in Ambala, Haryana, as model JL241/020.

Reading an Angle from Either Side
Put the centre mark on the point where the two lines meet and lay the straight edge along one of them. Follow the row of figures that starts at 0 on that line and read where the second line crosses the arc. Reading the other row gives 180° minus the angle, the usual slip when students switch sides.
Where It Is Used
In optics practicals it measures the angles of incidence, reflection and refraction traced around a glass slab, mirror or prism, always taken from the normal, so draw the normal first. In mechanics it sets and checks the slope of an inclined plane.
