Past and present WBGT meters

ROBINS AIR FORCE BASE, Ga. — A traditional Wet Bulb Globe Temperature meter, left, and a modern WBGT meter are held side by side at Robins Air Force Base, Georgia, March 30, 2026. When the traditional meter was used, it required deionized water and more time to get an accurate result than the modern alternative. (U.S. Air Force photo by Lauren Boggs)
