The Accutire Monitor by Measurement Ltd. is an affordable alternative to wheel-mounted TPM systems. Special features of the Accutire Monitor include:
- Four specially-designed caps that can be programmed with the correct tire pressure for each vehicle using a digital tire gauge.
- Once caps are placed on the tire valve, they stay in 'sleep' mode. Users need only hold the monitor gauge next to the cap to read the tire's air pressure.
- A green cap indicates a satisfactory tire pressure of 90-120 percent.
- A yellow cap indicates a slightly under-flated pressure of 80-90 percent.
- A red cap indicates under-inflation below 80 percent of pressure.
- A blue cap indicates the tire is over-inflated by more than 120 percent.
