1-800 M /S Multifunctional For Shooting Speed Meter Ball Velocity Energy Measurement Shooting Chronograph Speed

TYPE 1 Overviews: This product is made of DIY, the appearance requirementsHigh friends please take care! 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, nerf toy speed measurement, children's soft toys, etc.. Ts: This is a small overall, inappropriate test ! The speed of the instrument is not very understanding of friends can look at the video. Screen addre: tudou.com/programs/view/Kf3HYdAfy9k/ Features: 12 sets of infrared r heads before and after, to avoid leak detection Four-sided hollow design to prevent airflow interference Simultaneously record 40 sets of speed and kinetic energy data for easy viewing Large channel: 46*68mm Reference parameters Working voltage: DC3.7-4.2VAlready builtlithium battery) Working environment temperature: -30 ~ +60 Accuracy: test error≤1% Measuring range: 1-800 M /S Other: 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 by the air preure, please measure the distance from the hine 4-8 cm, so that the air flow can be disturbed to get stable and accurate data Function: velocity measurement /Speed energy/ Look through records Package included: 1 x Speed Meter 1 x Trod(Optional) 1 x USB Charging Cable

TYPE 2

Mainly used for learning and experiencing the high-speed data proceing ability of single-ch microcmputer and measuring the flight speed of various things. Such as: table tennis, badminton, arrow and so on. Core components are industrial-grade encapsulation with stable performance and small error.

Features: The panel is mainly composed of digital display tube, function, key and LED indicator. The function key is the micro touching on. Four sides of the air design, to effectively ease the impact of testing time. Improved stability and accuracy. Display surface and the operation of the on in front of the operation and to see the test data are very convenient. Mini size is easy to carry. Simple and easy operation. High accuracy measurement. As the device with high accuracy and clamp rail, and fixed equment after the path every time are the same, and with the guide rail can be made with the model in parallel, so the measurement result error is small, small fluctuation dynamic error. Function is more abundant. Not only can measure the speed, but also can measure the kine-tic energy, at the same time can record up to 40 groups of speed and the 40 group of the kine-tic energy value. Multle power management and protection. The lithium cell has the function of over charging, over discharging and short circuit protect, and the integrated intelligent shutdown and low power shutdown function.

Specifications: Working Voltage: DC4.2V Accuracy: test error le than or equal to 0.5% Measuring Range: 1-999m/s Cell(built-in): 1 * 3.7V 450mAh Lithium Cell Working Surrounding Temperature: -10℃ - 60℃ Speed Measurement Range: 1-999m/s Energy Measurement Range: 1-800J Weight Input Range 0.1-10g Speed Record: 40 group Kine-tic Energy Recording: 40 group Item Size: 130 * 80 * 50mm / 5.1 * 3.1 * 2.0in Package Size: 175 * 115 * 95mm / 6.9 * 4.5 * 3.7in Item Weight: 145g / 5.1ounce Package Weight: 240g / 8.5ounce

Notes: Please allow 1-30mm error due to manual measurement. Due to the difference between different monitors, the ture may not reflect the actual color of the item.
