Badminton Racket Tension Calibrator Plastic Badminton Racket String Meter String Machine Tools Black

Feature: 1. Hard Plastic Material: Badminton racket tension calibrator is made of high quality metal hard plasticl, reliable performance, sturdy, durable and long service life. 2. Easily Know Pressure Value: The special badminton racket tension calibrator can easily know the pressure value of the racket string and decide whether to replace the racket with a new string. 3. Understand Racket Pressure Value: With the racket pressure measuring device, you can roughly understand the racket pressure value, compare different time spans, know how many pounds a worn racket loses in a day. 4. Understand Racket Pressure Value: You can roughly understand know when to cut the ball line and replay it, and know what line of the ball is. The pounds fall fast, know what threading method the pounds fall slowly. 5. Small and Portable: Small size, light weight, easy to carry around with you, 0‑42 pounds range, clear reading, simple operation. Specification: Item Type: Badminton Racket Pressure Measuring Device Material: Hard Plastic Color: Black Weight: Approx. 91g / 3.2oz How to Use: Instructions for use of badminton racket tension calibrator:For a racket that has just been threaded or has been used for a period of time, the middle value of the racket surface measured by the racket pressure gauge is usually small, and the surrounding racket value tends to be in pounds. The line pressure value tends to be more in pounds. Therefore, we usually measure the surroundings (vertical lines at 2/4/8/10 o'clock) to understand the racket pressure value. How to use:1. Turn the disc counterclockwise to reset the scale to zero. 2. Place the two small cylinders of the pressure measuring instrument perpendicular to the surface of the racket and insert them in the cross direction. 3. In the direction of the cross. Turn the manometer clockwise, and when the vertical line is centered in the arrow of the manometer, find the time corresponding to the scale value of the dial.  Package List: 1 x Badminton Racket Tension Calibrator Note: 1. The racket pressure value is not exactly the same as the pound value, but some points tend to be the pound value. 2. This is a pressure gauge rather than a weight gauge. The main purpose is to measure the pressure of the racket and know whether to change the new line.
