以下是关于GED-2600发动机转速表的中英文介绍：

GED-2600发动机转速表是一款功能多样且实用的测量仪器。它既可以作为发动机转速表，通过电磁感应法非接触地测量各类汽油发动机的转速，也可作为激光转速表，利用光反射法非接触地测量发动机或发动机以外的各种旋转物体的转速。这种设计使得它在汽车制造、维修等行业得到了广泛应用。

该转速表具有数字显示功能，能够确保测量结果无视差，测量范围宽且分辨率高。它还能自动记忆测量期间的最大值、最小值及最后一个测量值。其结构坚固、精致，便于携带，整机采用经久耐用的电子元器件，外壳则采用重量轻而坚硬的ABS塑料，造型美观大方。

The GED-2600 engine tachometer is a versatile and practical measuring instrument. It can function as an engine tachometer, using electromagnetic induction to non - contactly measure the speed of various gasoline engines. It can also serve as a laser tachometer, employing light reflection to non - contactly measure the speed of various rotating objects, both engines and others. This design has made it widely used in the automotive manufacturing and repair industries.

The tachometer features digital display, ensuring no parallax in measurement results. It has a wide measurement range and high resolution. It can automatically remember the maximum, minimum, and last measurement values during the measurement period. The instrument is robust, compact, and portable, with durable electronic components and a lightweight, sturdy ABS plastic casing, which gives it an attractive appearance.
