USB Digital 433.92mhz Solar Tire Pressure Monitoring System
2.7 inch Universal external solar Tire pressure monitoring system
for passenger cars 433.92mhz
Specifications
The solar screen VA touch screen is more beautiful and has a wider
viewing angle. Because the screen needs to add an additional driver
The shell is made of new materials to prevent secondary pollution
from threatening human safety, and ABS+PC prevents deformation.
IP67 highly waterproof (soak it for 30 minutes after being immersed
in a meter of water for normal use)
Pre-explosion-proof tires, the tires will continue to have low
pressure or thermal expansion and contraction after a long time of
driving. This is the main cause of tire explosion. Using a tire
pressure monitoring system can further reduce tire wear and reduce
fuel consumption.

Features
Air leakage alarm
When the pressure drop of any tire exceeds 0.3Bar in one launch
cycle, the buzzer sounds quickly, at the same time, the
corresponding tire icon and pressure data, TPMS icon and air
leakage icon flash continuously, press any key to stop the buzzer
alarm; stop Fully released
Low voltage alarm
When any tire pressure is detected to be lower than 75% of the
standard tire pressure, the buzzer sounds an alarm, corresponding
to the tire icon and pressure data and TPMS icon
High voltage alarm
When it is detected that any tire pressure is higher than 125% of
the standard tire pressure value of the cold tire when the vehicle
is fully loaded, the buzzer sounds, and the corresponding tire icon
and pressure data, TPMS icon and high pressure icon flash
continuously, when the tire pressure is below After the alarm
threshold is 0.1Bar, the alarm is released; the factory setting of
the high-pressure alarm threshold is 3.2Bar, which is suitable for
all cars.
