轉(zhuǎn)速計，又名轉(zhuǎn)速表、轉(zhuǎn)速儀，是機械行業(yè)的儀器之一，用來測定電機的轉(zhuǎn)速、線速度或頻率。常用于電機、電扇、造紙、塑料、化纖、紡織、汽車、飛機、輪船等制造業(yè)。大多常用的為手持離心式轉(zhuǎn)速計。

例如Checkline DLM-107型轉(zhuǎn)速計/測長儀，主要是用來測織物和運輸帶的長度。

The Model Check-line DLM-107 Digital Length Meter is designed to accurately measure fabric length (or other moving belt material), in feet or meters.
