Product Description

High Accuracy Initial Speed Meter Velocity Velocimetry Tachometer Speed Measuring Instrument

Mainly used for learning and experiencing the high-speed data processing ability of single-chip 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.

  • The panel is mainly composed of digital display tube, function, key and LED indicator. The function key is the micro touching button

  • 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 button 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 equipment after the path every time are the same, and with the guide rail can be made with the mining 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 kinetic energy, at the same time can record up to 40 groups of speed and the 40 group of the kinetic energy value

  • Multiple 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

  • Notes:

  • Please allow 1-30mm error due to manual measurement.
