Ensure your safety on the road with the Masoll M13 Tire Pressure Monitoring System, a comprehensive solution designed for vehicles with four tires, including sedans, SUVs, pickup trucks, RVs, and travel trailers up to 38′ in length. This intelligent system eliminates the need for manual threshold configuration. By using your tires' standard pressure as a reference, the M13 automatically triggers an alert if pressure deviates by 25% above or 15% below the baseline. Furthermore, the sensors feature an auto-calibration function that updates the reference pressure whenever you inflate or deflate your tires, providing a seamless and hands-free monitoring experience.
Engineered for reliability and ease of use, the M13 features a high-definition, anti-reflective color LCD that automatically adjusts its brightness for optimal visibility in any lighting condition, from direct sunlight to nighttime driving. The monitor is powered by a high-efficiency solar panel with integrated overheat and overcharge protection, ensuring safe and continuous operation. To conserve energy, the system utilizes an intelligent auto wake-up and sleep function, activating only when needed. With a precise pressure detection range of 0 to 87 PSI and an accuracy rating of 1.5 PSI, this system helps you maintain your tires in peak condition, effectively reducing uneven wear and optimizing fuel efficiency for a smoother, more economical journey.
