RaceAir Pro™. This all new digital weather station incorporates all the great features from our track proven RaceAir™, such as automatic air sampling, an internal fan, and precision digital sensors for consistent air readings

The readings are stable and reliable, you won’t find the numbers jumping around. We use precise signal conditioning and professional grade sensors so you can rely on the information. Race Air humidity sensors receive a multi-point calibration to ensure full scale accuracy. The bone white case shields sensors from the effects of IR heat, yet provides ample ventilation for rapid response to ambient air changes. Only 3 5/8″ x 5 6/8″ x 1 1/4″ the Race Air is light weight. Display updates automatically every 10 seconds showing the current readings.
