Field notes
The D100 uses a fixed device length and a laser-measured gap to calculate the child's height, displaying the result to 0.1 cm. The same frame is presented for vertical measurements of 24–59-month-old children and horizontal measurements of younger children. The page cites a prospective Vietnam study involving 571 children, plus field demonstrations reporting faster measurements and a smaller team requirement.
