Meter Rule, Stainless Steel

Quick Answer: The Meter Rule, Stainless Steel is a metre-length rule made from stainless steel, graduated along its edge for measuring and marking out in laboratories and workshops. A stainless steel meter rule keeps a straight edge and legible graduations through heavy use.

A Rule That Doubles as a Straight Edge

Steel rules are thin compared with wooden ones, so the graduations sit right against the object being measured, which reduces parallax. The metal takes engraved or etched markings that do not rub off, and the edge can guide a scriber or craft knife without being cut. Stainless steel resists rust from handling and humid rooms, although it can still mark if left wet.

Many steel rules are end-reading, with the zero exactly at the end, so they can measure from a wall, a step or the inside of a box. That also means the end must be protected from knocks, because a burred end adds its error to every such reading. Whether this rule is end-reading, graduated on one or both edges, and marked in millimetres only, is worth asking about before ordering.

A thin steel rule bends easily when laid flat and pushed, so it is not the beam for hanging masses in moments work; the hardwood meter rule is made for that. The steel rule’s strengths are marking out, measuring fixed apparatus such as optical benches and resonance tubes, and workshop layout.

Specifications

Applications

• Marking out sheet metal, plywood and acrylic in workshop and STEM project work
• Setting distances on optical benches and measuring resonance tube lengths
• Guiding a scriber or craft knife for straight cuts in card and thin sheet
• Measuring bench-mounted apparatus where a durable, washable scale is needed

Care & Handling

• Hang it from its end hole, if it has one, or store it flat; do not drop it on its end.
• Wipe it dry after use and keep it away from acid fumes.
• Guide blades along the edge gently; heavy cutting pressure can burr the edge over time.
• Protect the zero end from knocks, because a damaged end shifts every end-reading measurement.

Why Choose LabEquip

Frequently Asked Questions

Why choose a stainless steel meter rule over a wooden one?

Steel keeps its graduations and straight edge through heavy use, is thin enough to reduce parallax, can guide a scriber or knife, and does not swell with moisture. Wooden rules are thicker and stiffer, which suits balancing experiments.

What is an end-reading rule?

It is a rule whose zero is exactly at its end, so it can measure from a surface the end is pushed against, such as a wall or the inside of a box. The end must stay undamaged, since any wear adds straight to the reading.

Can a steel rule be used for marking out?

Yes. Its hard, straight edge guides a scriber on metal or a pencil on wood, and its graduations help set out dimensions. Hold it firmly so it does not slip while scribing.

Does temperature affect a steel rule?

Steel expands slightly as it warms, but over normal room temperatures the change across a metre is very small compared with the reading resolution of a rule. It matters only in precise metrology, where corrections are applied.

Will it rust?

Stainless steel resists rust well in normal use. It can still stain if left wet, in contact with corroding metals, or in fume-laden air, so wipe it dry and store it away from the chemical store.

How do I read it without parallax error?

Lay the rule so its graduated edge touches the object, then look straight down at the mark. The thin steel edge brings the scale close to the object, which already cuts parallax compared with a thick rule.
