1. Sensor (Clamp-in/Snap-in,315MHz/433MHz) is the programmable universal sensor specially built for efficient sensor replacement. It perform like old sensors,in terms of signal interval,durability,and functionality. Featuring a convenient design that allows for quick installation and removal of the sensor,it is truly the ultimate TPMS solution. 2. Sensor(SW2IN1) is a programmable universal sensor specially built to combine both. 315MHz and 433MHz applications in ONE sensor for efficient replacement. 3. Featuring the exclusive release valve design to allow rubber and metal stems to interchange by hand,without a sensor head fitting tool. Performs like sensor signal interval,durability,and functionality. 4. Sensor(SW2IN1) can replace direct TPMS sensors fitted on wheels, including old equipment and programmable universal sensors. Our Sensors can be programmed to replaced 98% sensors on vehicles today. Sensor(SW2IN1) can be programmed by diagnostic scanner (eg. TS408 TS508 ITS600) to
