D Scale for Measuring Angles
D Scale for Measuring Angles (Product Code: SCL-308/052) is a large plyboard protractor used to set out and read angles during physics lessons and practicals. With a radius of about 30 cm and markings from 0° to 90° at 15° intervals, it can be read by a whole class and handled easily on the bench. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for mechanics lab equipment buyers in India and abroad.

What Is the D Scale Used For?
The D scale works as a demonstration-size protractor. Teachers use it at the front of the room to show how an angle is measured from a baseline, and students use it on the bench to set the angle of an inclined plane, check the tilt of a board or mark directions for force and ray diagrams. The large 15° steps make standard angles quick to set without hunting for fine divisions.
Because it is graduated in 15° steps rather than single degrees, it is meant for setting and demonstrating angles rather than precise measurement; pair it with a handheld protractor when a reading to the nearest degree is needed. Lay the straight edge along the baseline, align the centre with the vertex, and store the plyboard flat and dry so it stays true.

Frequently Asked Questions
What range does the D Scale for Measuring Angles cover?
The D Scale for Measuring Angles is marked from 0° to 90° in 15° intervals. That range covers the angles most often set in school practicals, such as inclines and ray directions, and the large steps are easy to read across a classroom.
How big is the D Scale for Measuring Angles?
The D Scale for Measuring Angles has a radius of about 30 cm. Its size makes it suitable as a teacher’s demonstration protractor and for setting angles on bench apparatus where a small student protractor would be hard to hold in place.
What is the D Scale for Measuring Angles made of?
The D Scale for Measuring Angles is made of plyboard. Plyboard is light, stiff and easy to handle; keep it dry and store it flat so the board stays true and the markings remain clear through years of classroom use.
Can the D scale measure angles to one degree?
No, the D Scale for Measuring Angles is graduated at 15° intervals, so it is meant for setting and demonstrating standard angles rather than reading single degrees. For finer readings, use it alongside a handheld protractor.
Who manufactures the D Scale for Measuring Angles?
The D Scale for Measuring Angles is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and repeat orders come directly from the manufacturer.
How do I get a quotation for the D scale?
To get a quotation for the D Scale for Measuring Angles, send the product code SCL-308/052, the quantity and the delivery location through the ScienceLab contact page. Schools, dealers and importers in India and international markets can order single pieces or class sets.
