The machine body can fixed on the wall through the fixed suport,or fix it on the floor.The machine body can be installed on the wall through the fixed suport, or on the floor. The test process is controlled by intelligent MCU, read the turns of the trolling reel through the encoder pulse, calculate the increment of each circle by considering the line of the reel increasing on the first circle. And improve the measurement accuracy value by taking multi-point to calculate. Interface display: rotating speed, length, start/stop/reset. (digital display, page display the speed and length);Length measuring system, DC motor with speed adjustment, intelligent MCU control.Wall fixing suport or floor stand seat(adjustable)Encoder and intelligent control signal transmission systemRotating speed:1-150(adjustable)   Stroke:0-1000MM(adjustable)Standard: ASTM963-08
