The exact answer to the question "What instrument is used to measure the height of a person?" is a stadiometer.
The Stadiometer: Measuring Human Height Accurately
A stadiometer is a fundamental piece of medical equipment specifically designed for precisely measuring human height. As indicated by the reference, it is used in various settings, from routine health check-ups to specialized research.
How a Stadiometer Works
The typical construction of a stadiometer, as described in the reference, involves two primary components:
- A ruler or scale, usually mounted vertically against a wall or as a standalone unit.
- A sliding horizontal headpiece that is carefully lowered until it rests flat on the top of the person's head.
The person stands with their back against the ruler, and the headpiece is adjusted. The height measurement is then read directly from the scale where the headpiece aligns. This design ensures consistent and reliable measurements.
Common Applications
Stadiometers are essential tools in several fields. According to the reference, their uses include:
- Routine medical examinations: Height is a standard measurement taken during physical check-ups for people of all ages.
- Clinical tests and experiments: Accurate height data is often required for various medical studies, growth monitoring, and calculating body mass index (BMI).
Using a stadiometer provides a more accurate measurement compared to using a simple measuring tape, especially in clinical or research settings where precision is important.
Instrument Summary
Here's a quick look at the key details:
| Instrument | Primary Purpose | Key Components | Common Settings |
|---|---|---|---|
| Stadiometer | Measuring Human Height | Ruler (Scale), Sliding Headpiece | Medical offices, Clinics, Research |
Understanding the tools used for basic anthropometric measurements like height is crucial in healthcare and scientific research.
