All TV2 products use the QuickCheck display. The display is a full color EasyTouch display that changes its configuration depending on what type of sensors it is being used with. Sensors, whether temperature, temperature + humidity or differential pressure, can be plugged into any of its four sockets if they are wired sensors. Up to four wireless sensors can be linked to the display. The values displayed, whether temperature, pressure or humidity will turn red if the condition becomes unsafe. It will remain red until the condition becomes safe once more.
