Metal Ruler Manufacturer,Supplier and Exporter in India

Metal Ruler (Product Code: SCL1211/04) is a graduated stainless steel rule 100 cm long, with a true straight edge that serves both for reading lengths and for ruling lines. Physics teachers use it where a short plastic scale is not enough: reading the extension of a spring, setting the length of a pendulum or spacing a lens and screen on the bench. The ruler is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its mechanics lab equipment in India for schools and colleges.

Specifications

Typical Use

In a Hooke's law practical the ruler is clamped upright beside a hanging spring, and students note the position of a pointer each time a mass is added, turning the readings into a force-extension graph. It is equally handy for measuring the length of a simple pendulum from the point of suspension to the centre of the bob, for object and image distances in lens work, and for drawing long, clean lines on charts and posters.

Because the strip is only 0.5 mm thick, the graduations sit close to the object being measured, which helps students avoid parallax when they look straight down on the scale. A thin steel rule can flex, so support it along its length on the bench when taking a reading. Stainless steel does not swell like wood and wipes clean easily, which keeps this ruler serviceable in busy school physics lab equipment sets in India for many batches of students.

Frequently Asked Questions

How long is the ruler and is it graduated along its length?
It is 100 cm long and graduated. If you need the exact graduation interval before ordering, we can confirm it on request.

Why choose stainless steel over a wooden or plastic scale?
Stainless steel keeps a straight edge, does not warp with humidity and is easy to clean. Its 0.5 mm thickness also keeps the scale close to the object, reducing parallax.

Can it be held vertically in a clamp?
Yes, it can be held upright in a clamp on a stand for spring and pendulum work. Make sure your clamp jaws close firmly on a thin strip 2 to 3 cm wide.

How should it be stored?
Store it flat in a drawer or hang it from a hook so it is not bent under other apparatus, and wipe off any moisture after use.

Is the edge safe for students?
It is a thin metal strip, so students should carry it carefully and not use it for cutting or prising. Normal classroom handling is otherwise straightforward.

What details should a school include in its purchase request?
Give the product code SCL1211/04, the quantity, the delivery address and any vendor documents your institution needs. We quote bulk orders for India and international markets.
