Ideal for motorhomes and small vans with 6 wheels (twin tires or double axles) and tire pressure over 4 bar. Vehicles over 3.5 tons require an additional booster/repeater for safe operation. It continuously displays the current tire pressures for all 6 tires and can be expanded to a maximum of 10 sensors/wheels. With this, you will always have the information that you are traveling with optimal tire pressure, saving fuel and tires while making an important contribution to protecting our environment. In case of an alert (pressure loss), you receive a visual and audible warning through backlighting and a signal indicator. It can be installed in just 5 minutes and does not need to be initialized; the batteries are replaceable. One set of sensors is sufficient for both summer and winter tires.
