A slim, cig-lighter style TPMS for 4WD, passenger vehicles, some motorhomes, and mini buses 

The Steelmate TP-77 is a DIY TPMS that allows the driver to monitor 4 tyres in real time using an easy-to-see LCD display. It also comes with a USB slot which allows drivers to charge their phones or use other electronics.

The system can monitor tyre pressure from as low as 10 psi, which is perfect for 4WDers, and up to 75 psi, which is also appealing to some drivers of maxi taxis, cars, motorhomes and mini buses etc.

The system monitors both pressure and temperature, and will alert the driver of leaks, punctures or over-heating (over 80 °C/176°F) and low battery etc.

In addition, the alarm threshold of pressure ( Mid-value) can be set and adjusted by the driver ( adjustable mid-value range is 18~66Psi), and the monitoring range will become minus and plus 8psi of the mid-value.

Installation is a breeze – Simply plug the LCD display into the vehicle Cig-lighter socket. Screw the pressure sensors onto the valves and replacing the valve caps. The sensors are pre-configured and labeled, and you are ready to go.
