Our special OTR TPMS systems are normally sold as a set including 4 OTR sensors.
The OTR systems can be extended by adding extra sensors that are sold separately.
These OTR sensors can also be used in combination with any of our professional Truck TPMS systems. That allows you to choose either the stand-alone or 1-DIN monitor version, or one of our monitors with either RS-232 or CAN Bus data connectivity.
This will allow you to use the advantages of our TPMS systems on almost any type of vehicle.
