{"@context":"https://schema.org","@type":"Product","name":"GRUNDIG D550 TPMS for RVs & Trucks, 6–40 Wheel Monitoring, 200 PSI, Independent Axle Pressure Alerts Setup, Real-Time Tire Pressure & Temp Alerts","description":"Key Product Highlights Massive 6-40 Wheel Monitoring (Up to 200 PSI): Specially engineered for ultimate flexibility, supporting anywhere from 6 to 40 tires simultaneously with an ultra-high 200 PSI max pressure limit. Perfect for extreme heavy-duty commercial fleets, RVs, and multi-axle trailers. Independent Axle Alarm Settings (Tractor/Trailer): Crucial for towing! You can program separate high and low-pressure alarm thresholds for your main vehicle (tractor) and your towed vehicle (trailer). Customize your safety parameters perfectly matched to different axle loads. Premium German Infineon Microchip: Equipped with an advanced Infineon processor running at 433.92MHz. Ensures rapid signal transmission, exceptionally low power consumption, and robust anti-interference stability over long commercial vehicle setups. 3-Second Real-Time Updates: Predicts air leakage instantly with ultra-fast 3-second data refresh rates. Provides accurate real-time monitoring of tire pressure, temperature, and sensor battery levels to prevent flat tires and reduce tire wear. Comprehensive Safety Alerts: Instant visual and audible alarms for Quick Air Leakage, High/Low Tire Pressure, High Temperature, Sensor Low Battery, and Sensor Faults. Wireless & Compact Display: A sleek 120mm × 73mm display designed for wireless transmission and easy placement anywhere on your instrument panel, ensuring driving safety is always in focus. Powered by German Infineon Microchip At the core of the D550 TPMS lies the highly responsive German Infineon Microchip . Operating on a stable 433.92MHz frequency, it adapts to a variety of harsh environments. It guarantees signal stability, accurate data rendering, responsive feedback, and long receiving distances while maintaining remarkably low power consumption. Independent Axle Alarm Settings ★ Set Different Alarms for Your Main Rig and Trailer! Our advanced programmable system recognizes that your heavy-duty truck and your towed trailer operate under different load stresses. The D550 empowers you to set completely independent high-pressure and low-pressure thresholds for different axles . This ensures you never get false alarms when your main vehicle requires 110 PSI but your trailer only requires 80 PSI. Real-Time Safety Alarm Formats The D550 system dynamically adapts its user interface based on the number of wheels you are monitoring.
