Stadiometers measure height and are commonly found in medical settings. They can be mechanical or electronic, wall-mounted or portable, and vary in price and construction. Newborns are measured with different equipment such as infant poles or rubber rulers.
A stadiometer is a device that is used to measure height. It is most commonly found in medical settings such as doctor’s offices. Stadiometers are typically used for regular medical exams, although they are also used for other types of tests and experiments. A typical design consists of a ruler mounted vertically on a wall, with a movable horizontal piece resting on the head of the person being measured. This piece shows height based on its position on the ruler.
While the mechanical wall-mounted stadium meter has continued to be popular, there are several versions of this equipment. Some models use an electronic sensor to measure height, which is then displayed on a digital reader. There are also lightweight, portable stadium meters that can be used against a wall or on a stand.
Some wall-mounted stadium meters have hinges so they can be moved flat against the wall when not in use. There’s also a retractable model that works similar to a tape measure. Once the tape has been extended to the full height of the patient, it can be locked and the results are displayed in a window on the tape dispenser.
A typical stadiometer will measure in both centimeters and inches, but the number of increments between these can vary between different models. Most models also have a way to lock the headgear so that an accurate measurement can be recorded. They tend to be made from materials such as aluminum or sturdy plastic.
The price and construction of a stadium meter can vary widely. A typical doctor’s office will usually purchase a simple model and may find that a mechanical device is sufficient. Laboratories and other research facilities tend to use high-end digital models that ensure greater accuracy.
Newborns are measured while lying down, so doctors use a different type of equipment to determine their height. The closest device to a stadium meter is the infant pole, which is essentially a smaller version of the same piece of equipment and is used horizontally. Another device is a rubber ruler large enough to fit the child’s entire body. It has a metal headrest that extends vertically from the rubber mat and a movable footrest that rests on the fully extended child’s feet to determine a hand reading. Another device is this infantometer, which is a sort of plastic trough with a moveable foot that shows height through a window on the side of the device that rests on a ruler.
