AN-01D 2 in 1 Car Solar TPMS Clock LCD Display Auto Tyre Pressure Temperature Monitoring Alarm System with 4 Sensors Description: Real-time monitoring function: Whether the vehicle is driving or stationary, the pressure and temperature status of each tire can be monitored, and the tire status is under control. High/low pressure alarm function: When the tire pressure is higher or lower than the set value, the system will alarm. Air leak alarm function: If a foreign object penetrates the tire to cause air leak, the system will alarm. High temperature alarm function: When the tire temperature exceeds 80, the system will alarm. Ultra-low energy consumption function: extremely optimized working mode, system battery life up to 5 years. Feature: High-efficiency solar panel, super battery life. Large-capacity built-in metal lithium battery, unimpeded battery life in cloudy days. Accurately monitor tire pressure stability throughout the process. LCD high precision liquid crystal display. High volume alarm sound warning. Multiple tire pressure units are available. Long receiving distance, stable signal. Support tire position interchange. Tire pressure detection system. Tire pressure alarm, solar charging, wireless transmission. Monitor 4 tires at the same time, color screen display. Built-in high-precision clock chip, 12/24 hour format. Prevent problems before they occur: prevent flat tire, air leaks, balance air pressure, save fuel, and reduce wear. Two types of sensors: external, built-in, ready to use, four wheels with the same display External sensor Battery life is about two years, replaceable (installed on valve core). The surface of the shell adopts anti-corrosion coating. Use hexagonal nut anti-theft patent. Adopting a unique external tire pressure sealing and ventilation mechanism patented silicone integrated molding structure to prevent air leakage Internal sensor The battery life is about five years, and the battery can be replaced (replace the valve core of the original car and balance it after installation.) Adopt aviation road alloy material nozzle. Battery from Japan. The shell is made of nylon chemical fiber material to prevent corrosion. An adjustable angle link is used between the air nozzle and the sensor to ensure that the angle is adjusted to be flush with the edge of the groove of the wheel during installation.
