Masten iTPMS for Android and iOS Devices. With Premium DIY Cap Sensors and Replacement Battery.


Spare Sensors:

If you're after spare sensors the part numbers are TP-12S (internal valve) and TP-11S (external cap)


The Masten TP-11 TPMS Tyre Pressure Monitor System is specifically designed for Smart Phones and the included (via download) iTPMS Application which is suitable for most types of vehicles including Cars, Trucks, Buses, Motorcycles and more.

The TPMS module simply receives a wireless signal from the 4 sensors and send the information by Bluetooth to your Smart Device. 

Feature List:

  • Smart Phone Bluetooth module specifically designed for Android and iOS devices
  • Monitor the pressure/temperature of four wheels at the touch of a button through your Smart Device
  • Simple installation! Just connect the module to your Smart Device by pairing the Bluetooth of the iTPMS to your Device. 
  • The multi colour interface allows you to easily identify problem tyres in red for fast evaluation
  • User programmable high and low pressure range
  • High quality cap sensors
  • Can monitor 2, 3, 4 or 6 sensors simultaneously. 
  • 2 Year Battery Life
  • User friendly programming functions


Sensor Specifications:

Sleep Function:

If the sensors have not been moved for 1 hour or more they will be in sleep mode. After around 5 seconds of movement the sensors will 'wake' up and start sending the tyre information data (pressure/temperature) every 6 seconds to the monitor.

What are Tyre Pressure Monitor Systems?

passenger vehicles in the 1980s and today is a mandatory feature in the United States. 


Benefits of a Masten TPMS?

The dynamic behavior of a pneumatic tire is closely connected to its inflation pressure. Key factors like braking distance and lateral stability require the inflation pressures to be adjusted and kept as specified by the vehicle manufacturer. Extreme under-inflation can even lead to thermal and mechanical overload caused by overheating and subsequent, sudden destruction of the tire itself. Additionally, fuel efficiency and tire wear are severely affected by under-inflation. Tires do not only leak air if punctured, they also leak air naturally, and over a year, even a typical new, properly mounted tire can lose from 20 to 60 kPa (3 to 9 psi), roughly 10% or even more of its initial pressure.

The significant advantages of TPMS are summarized as follows:

Fuel savings: According to the GITI, for every 10% of under-inflation on each tire on a vehicle, a 1% reduction in fuel economy will occur. In the United States alone, the Department of Transportation estimates that under inflated tires waste 2 billion US gallons (7,600,000 m3) of fuel each year.

Extended tire life: Under inflated tires are the #1 cause of tire failure and contribute to tire disintegration, heat buildup, ply separation and sidewall/casing breakdowns. Further, a difference of 10 lbs. in pressure on a set of duals literally drags the lower pressured tire 13 feet per mile. Moreover, running a tire even briefly on inadequate pressure breaks down the casing and prevents the ability to retread. It is important to note that not all sudden tire failures are caused by under-inflation. Structural damages caused, for example, by hitting sharp curbs or potholes, can also lead to sudden tire failures, even a certain time after the damaging incident. These cannot be proactively detected by any TPMS.

Decreased downtime and maintenance: Under-inflated tires lead to costly hours of downtime and maintenance.

Improved safety: Under-inflated tires lead to tread separation and tire failure, resulting in 40,000 accidents, 33,000 injuries and over 650 deaths per year. Further, tires properly inflated add greater stability, handling and braking efficiencies and provide greater safety for the driver, the vehicle, the loads and others on the road.

Environmental efficiency: Under-inflated tires, as estimated by the Department of Transportation, release over 57.5 billion pounds of unnecessary carbon-monoxide pollutants into the atmosphere each year in the United States alone.
