Truck Systems Technology (TST) provides the best Tire Pressure Monitoring System (TPMS) for RVs on the market. Everything you need to monitor 2 tires is included in this kit. The TST 507 color monitor alarms you in the event of low pressure, high pressure, rapid pressure loss, slow leaks, and high temperature giving you time to get off the road before a possible blowout occurs. The TST signal repeater ensures you always have a strong signal from your sensors to the monitor. With 2 mounting options, the color monitor auto-scrolls providing important real-time tire information. The monitor’s rechargeable battery provides 16-20 hours of continuous use without the need for extra cables on the dash. The TST cap sensor can be used with metal or rubber valve stems and features a user-replaceable battery. You can always add more sensors to your system at a later date if you change your tire configuration. Your TST 507 2 Cap Sensor Kit includes: * Color Monitor * 2 Cap Sensors * USB/DC Power Supply * Signal Repeater * Rubber Dash Pad Mount * Suction Cup Window Mount * Locking Hex Nut and Tool * Replacement O-Ring Kit * Exclusive TechnoRV Learning Series
