The three current products of LAUNCH LTR series RF tire pressure sensors all support 433MHz/315MHz frequency, and send more accurate data to the on-board computer through RF signals, which is suitable for users with higher requirements for tire pressure. This type of sensor has more outstanding performance. The battery life of RF sensors is usually longer, up to 4-5 years, reducing the frequency of replacement.
This article will compare these three sensors(LTR05(LTR-V), LTR03, LTR01) to see what are the differences between them.

As can be seen from the chart, the three LAUNCH LTR tire pressure sensors are actually the same in function, but they differ slightly in size and weight. Users do not need to worry about the difference in performance parameters of tire pressure sensors. They can just choose the appropriate size according to their needs.
