O paquímetro é um instrumento usado para medir 
dimensões e distâncias internas ou externas. 
Ele permite que você tire medidas mais 
precisas do que seria possível apenas com réguas 
convencionais.

1 - Entenda as partes de um paquímetro 
Esse instrumento tem orelhas usadas para medir o diâmetro externo e outras, menores, para a 
medição do diâmetro interno dos objetos. Alguns modelos também possuem uma régua de 
profundidade. A escala principal está fixa no lugar, enquanto o nônio representa a escala 
deslizante que abre e fecha as orelhas.

2 - Leia os valores no nônio
Cada valor no instrumento é lido como em uma régua convencional. Normalmente, ele tem uma 
escala principal marcada com polegadas ou centímetros numerados, além de divisões menores 
entre eles. A escala deslizante (nônio) terá um rótulo fixo que indica o que ele representa. Se a 
escala deslizante não tiver um rótulo, você pode assumir que as divisões numeradas representam 
1/10 da menor divisão presente na escala principal. Por exemplo, se as menores linhas da escala 
representam 0,1 centímetro, cada divisão numerada no nônio equivalerá a 0,01 centímetro.
A escala principal é "em tamanho real", mas a deslizante é ampliada para facilitar a leitura. Essa 
amplificação permite ao nônio dar medidas mais precisas do que uma régua convencional.
