转速计，又名转速表、转速仪，是机械行业的仪器之一，用来测定电机的转速、线速度或频率。常用于电机、电扇、造纸、塑料、化纤、纺织、汽车、飞机、轮船等制造业。 大多常用的为手持离心式转速计。
转速计，又名转速表、转速仪，是机械行业的仪器之一，用来测定电机的转速、线速度或频率。常用于电机、电扇、造纸、塑料、化纤、纺织、汽车、飞机、轮船等制造业。 大多常用的为手持离心式转速计。美国Checkline旗下的转速计一般为数字式，有接触式和非接触式两种测量。非接触式采用光电器件测量，无连接轴，对被测件无任何影响，提高测量精度。
例如Checkline CDT-2000HD型转速计，兼有接触式与非接触式两种测量方式，精准测量转速，表速和长度。可选用Checkline CDT-1000HD型。
CDT-2000HD运用：
The CHECK•LINE® CDT-2000HD Combination Hand-Held Digital Tachometer combines the best features of both contact and noncontact models to accurately measure RPM, surface speed and length. When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The CDT-2000HD can be up to 24 inches away from the small piece of reflective tape that is affixed to the rotating element. In the contact operating mode, the speed is sensed by directly contacting the rotating device using the cone tip or surface speed wheel supplied with the instrument. The CDT-2000HD's rugged construction, portability and outstanding features make it an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications.
CHECK-LINE便携式手持数字转速表CDT-2000HD，广泛运用于不同机械和材料处理应用程序。集成接触式和非接触式两种模式，测量更加精准，可测转速，线速度和长度。在非接触模式下，通过可见光束测转速。可以在距离测量件小片放光带24英寸的情况下测量。在接触式模式下，运用自带配件锥头和表速轮接触旋转装置来感应速度。CDT-2000HD机身结实、使用便携和，是维修人员，机械操作员和用户的理想之选。
