轉速計，又名轉速表、轉速儀，是機械行業的儀器之一，用來測定電機的轉速、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。 大多常用的為手持離心式轉速計。美國Checkline旗下的轉速計一般為數字式，有接觸式和非接觸式兩種測量。非接觸式采用光電器件測量，無連接軸，對被測件無任何影響，提高測量精度。
例如Checkline DT-105A/DT-107A型是一款手持接觸式轉速計，自帶周長為12英寸的主輪，使得表面速度測量更加安全簡單。

Accurately measure rotational and surface speed, as well as length. Built-in selector switch permits the user to display readings in a wide variety of engineering units. The Check-Line DT-105/7A-12 includes a 12" circumference measuring wheel which is offered for safer and easier surface speed measurement by keeping the users hａnd farther from the moving surface and slowing down the rotational speed.
Built-in memory for last, maximum, minimum and 10 separate readings
Rugged cast aluminum housing
Includes Traceable calibration Certificate
