Weather-Ometer tests parts for durability

April 13, 2023
The updated Ci4400 demonstrates how materials and products, such as plastic parts, degrade when exposed to light, extreme temperatures and humidity.

Ci4400 Weather-Ometer This locker-like unit from Atlas provides an enclosed environment for testing how materials and products, such as plastic parts, degrade when exposed to varying levels of light, extreme temperatures and humidity. Using xenon lamps and advanced filter systems, it can simulate solar radiation. The unit has a total exposure area of 1,130 square inches. It can produce temperatures up to 248 degrees Fahrenheit.  

What’s new? The option of a sealed lamp rather than Atlas’s standard daylight-simulating lamp/light filter assembly. It also is available as a retrofit to the now-obsolete Ci4000 Weather-Ometer. 

Benefits Ease of use, convenience and flexibility. Atlas’s WXView II web-based application allows the user to control the Ci4400 Weather-Ometer from anywhere, and to review and analyze instrument data  including files from archived tests  in a clear and concise graphical format. Protected by a 1,200-hour warranty, the new sealed lamp design incorporates all assembly elements  xenon-arc lamp, inner glass filter, outer glass filter and associated hardware – into a single, factory-sealed unit.
