[Efficient Power Usage and Precise Data Reading Sensors]: The Tymate Tire Pressure Monitoring System M7-3 boasts four advanced external sensors known for their low power consumption (operating for up to six months on a single CR1632 battery) and extended lifespan (with a maximum of two years). These sensors are compact, lightweight, and offer high accuracy in tire pressure readings, with minimal margin for error (approximately 3psi). Their easy installation and resilience make them suitable for use in challenging environments. All sensors included in the package are pre-labeled and paired with the monitor at the factory, there is no need to pair each sensor before use.
