例如Checkline CDT-2000HD型轉速計，兼有接觸式與非接觸式兩種測量方式，精準測量轉速，表速和長度。可選用Checkline CDT-1000HD型。
CDT-2000HD運用：
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便攜式手持數字轉速表CDT-2000HD，廣泛運用于不同機械和材料處理應用程序。集成接觸式和非接觸式兩種模式，測量更加精準，可測轉速，線速度和長度。在非接觸模式下，通過可見光束測轉速。可以在距離測量件小片放光帶24英寸的情況下測量。在接觸式模式下，運用自帶配件錐頭和表速輪接觸旋轉裝置來感應速度。CDT-2000HD機身結實、使用便攜和，是維修人員，機械操作員和用戶的理想之選。
