LCD screen, white backlight, no parallax.

Automatic display prompt for low voltage.

Frequency measurability.

The rotating shaft's linear speed is measurable in the case of a given radius. The  rotating shaft's radius may be set at 2-999mm.

The 4:1 low-rotating speed measurement mode promises a more accurate measurement of the  rotating speed.

A filtering lens can receive the red light of specific wavelengths only, thus avoiding  parasitic light effectively.

The function of automatic recording of the maximum, the minimum and the last value, and  the continuous mode which can realize savings of over 18,000 data groups.

A MINI USB interface makes data transmission easier.
