PressurePro has added several new improvements to their current product line, and has introduced new products to their Truck line also. Notably, the addition of RS232 communications as well as an upper pressure alert on all Monitors is now a standard feature. The upper alert is variable; it is set at the factory to alert at 24% high, but can be manually set at various settings from 10% to 45% under/over the set point. There are also two lower alerts: one at 12.5% and a second alert at 25% below the initial set point. All Monitors with RS232 capability can also display temperature when used with a tire management software program.
