Muzzle Speed Meter Velocimetry Velocity Anemometer Valence Tester with Tripod Muzzle Speedometer Tes

Effective induction area, high sensitivity. Strong adaptability, stable performance and high precision.The tachometer is mainly used for:Physical acceleration experiment, projectile free fall experiment, toy speed measurement, children's soft toys, etc..12 sets of infrared sensor heads before and after, to avoid leak detectionFour-sided hollow design to prevent airflow interferenceSimultaneously record 40 sets of speed and kinetic energy data for easy viewingWorking voltage: DC3.7-4.2VAlready builtlithium battery)Working environment temperature: -30 ~ +60Accuracy: test error less than or equal to 1%Measuring range: 1-800 M \/SOther: the four sides of the hollow design, not only visual field, but also to alleviate the impact of airflow measurement. Improved stability and accuracy of the test.To measure the velocity of the projectile propelled by the air pressure, please measure the distance from the machine 4-8 cm, so that the air flow can be to get stable and accurate dataFunction: velocity measurement \/Speed energy\/ Look through recordsColour: blackMaterial: plasticPackage Contents:1 * tachometer1 * tripodOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
