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。
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-12CBL型是一款手持接觸式轉速計，法蘭和橡膠接觸表面設計，再配備周長為12英寸的主輪，使得速度測量更加安全精準。
The DT-105A-12CBL is designed to measure elevator cable speed in feet per minute, meters per minute and other measuring units. It is supplied with a rugged 12” circumference wheel with large flanges to keep the cable in contact with the surface. Delivering superior performance and accuracy over more conventional flat surface wheels
Employing a non slip rubber contact surface, the wheel adds safety and accuracy while measuring speeds on Elevator governor cables, wire and cable reels, extruded tubing and many other applications
Built-in memory for last, maximum, minimum and 10 separate readings
Rugged cast aluminum housing
Includes Traceable calibration Certificate
