1. The product uses a large LCD screen, reading data is clear and convenient. 2. Supports switching between in/mm units, you can get data as needed. 3. For measuring the tread depth, it can quickly measure the depth of the tire tread, which is convenient for judging the wear of the tire and effectively warning the potential traffic accident. 4. The operation is simple, after multiple measurements, the average value can be obtained to obtain relatively accurate tire wear. 5. High measurement precision, stable operation and long service life.

Specification: Measuring range: 0- 25.4mm Resolution: 0.01mm Tolerance:  ± 0.1mm Battery: LR44 type 1.5V button battery(No-include) Probe diameter: 1.6mm Color: silver Package list: 1 * Tread Depth Gauge Note: The actual product color may deviate from the photo due to light. There may be a slight deviation in the measurement of product. Instructions: 1. The measuring surface is close to the flat surface, push the measuring rod to the end, press ZREO to clear the key, and display 0. 00. 2. The measuring surface is vertically attached to the tread surface of the wheel tire, and the measuring rod can be inserted into the bottom of the pattern groove to measure the value. (It is recommended to measure several times and take the average)
