Stay safer on the road and protect your RV tires with the TST 770 Series 4 Flow-Thru TPMS System with Color Touch Display & Repeater (TST-770-FT-4-TC). Designed for RVers and towable setups, this advanced tire pressure monitoring system includes a large 5" color touch screen display, repeater, and four flow-thru sensors to deliver real-time tire pressure and temperature data. The easy-to-read touchscreen allows quick setup and simple programming, while the system continuously monitors for low pressure, high pressure, rapid leaks, and high tire temperatures. When an issue is detected, both audible and visual alerts immediately highlight the affected tire by locking onto it and turning it red on the display. Built for flexibility, the expandable 770 Series system can monitor additional axles, spare tires, and even a towing vehicle with added sensors. The rechargeable display uses a convenient USB-C charger and features a metal backing plate for secure mounting with the included magnetic mount. Note: Metal valve stems are required when using flow-thru sensors.
