• 1. Real-Time TPMS Monitoring for Maximum Road Safety—— Equipped with a 4.5" color display, this system shows real-time tire pressure (0-188 PSI) and temperature for your trailer, RV, semi truck, 5th wheel, camper, or motorhome. It supports 4-22 tires with a signal booster/repeater for stable long-distance transmission. Six advanced alerts notify you of low/high pressure, rapid air leak, high temperature, sensor data loss, and low battery, helping prevent blowouts and breakdowns on the road.
• 2. Time-Saving Flow-Through Sensors——Our flow-through design lets you inflate tires directly without removing the sensors, saving you time and hassle on long hauls. With ±1 PSI high accuracy and IP67 waterproof construction, the sensors reduce uneven tire wear, extend tire life, and lower maintenance costs. Note: Not compatible with extremely short rubber valve stems.
• 3. Smart Power Saving & Wide Temperature Resistance——Built-in auto sleep mode activates after 5 minutes of inactivity to save power. The system operates reliably in extreme temperatures from -4°F to 185°F. After startup, it fully updates all tire data within 5–10 minutes while still providing instant rapid leak alerts.
• 4. Fast Installation & Flexible Customization——Tool-free 3-minute setup makes installation quick and easy. The intuitive interface allows you to set custom pressure thresholds per axle for personalized monitoring, so you can tailor the system to your truck, trailer, or RV setup.
• 5. Anti-Theft Design & Stable Long-Trailer Signal——Sensors come with anti-theft locking nuts to secure your investment. The included signal booster/repeater ensures strong, stable reception even on 130ft long trailers and semi-trucks. IP67 rugged construction withstands harsh road conditions, backed by reliable after-sales support.
