(Atlas/AMETEK: Mount Prospect, IL) -- Atlas/AMETEK has introduced the Atlas S³T system, the latest advancement from a leader in accelerated artificial and natural weathering testing. Designed for Weather-Ometer Ci4400 and Ci5000 instruments, the Atlas S³T system makes it possible to continuously measure the specific surface temperature of individual samples during live testing.

Surface temperature is a critical factor for the rate of photochemical reactions in weathering. But until now, the measurement of surface temperatures has not been feasible for multiple samples in laboratory weathering instruments. As a result, surface temperature is often neglected during testing or only roughly estimated based on black-and-white standard or panel reference temperatures.
