Reliable depth accuracy Provides precise tire tread depth measurement with 0.01 mm accuracy and a clear electronic digital display for easy reading. Streamlined calibration Spring reset mechanism enables fast zero, minimizes calibration errors, simplifies measurement, and reduces total operating time. Durable quality Rugged construction using high-quality materials and wear-resistant technology delivers high impact resistance and consistent performance, extending service life. Wide compatibility Ideal for safety tire testing from passenger cars to trucks; operates on different surfaces to meet daily measuring needs. Use scenarios - Auto service shops: perform quick tread depth checks during routine inspections or tire rotations to verify safe tire conditions. - Fleet maintenance: monitor tread depth on mixed fleets (cars, vans, trucks) across varying road surfaces to maintain safety standards. - Roadside or home garage: convenient tire inspections before long trips, across different surfaces and driving conditions.
