Fobo Standard and Fobo Plus are discontinued and have been replaced by Fobo Tyre 2
The only difference between the 2 products is the pressure.
Fobo (Standard) can monitor up to 50psi. We recommend use of Fobo (Standard) for normal operating settings of up to 43psi. Allowance needs to be made for pressure fluctuation and upper alert threshold.
Fobo Plus can monitor up to 87psi and we recommend using for setting of up to 80psi.
