BeeSpi V Speed Measuring Tool
Product Number: SB47275
With the push of a button accurately measure the velocity of small objects. Ideal for use in experimental tests of speed and acceleration. BeeSpi detects an object passing through two points about 40 mm apart via built-in photo-sensors and indicates the velocity of the object in digital form. Infrared sensors located at two spots on the inside wall of the unit detect the time when the object passes each spot, and the velocity of the object, calculated from the time difference, is indicated. Measures speed and cumulative lap time, and the use of two BeeSpi units allow acceleration to be determined. Measures in km/h, m/s, and cm/s. Memory stores the last five measurements. Features a start button and a select button.
