Ci4400 Weather-Ometer® Unmatched Repeatability and Reproducibility

The Atlas Ci4400 Weather-Ometer® is our most advanced instrument yet providing easy and effortless operation, unmatched uniformity, increased capacity and a sleeker design, delivering unparalleled value and performance. With its user-friendly touch screen interface and ergonomic features, the best-in-class just got even better.

Design and engineering innovations in the airflow, irradiance and control systems have dramatically reduced variability in critical test parameters. As a result, the Ci4400 achieves new levels of temperature, humidity and light exposure uniformity.

Simplified Control Navigation

The larger user interface makes operating the Weather-Ometer easier than ever. The Ci4400 delivers exceptionally precise and reliable control of all test parameters for repeatable, reproducible and reliable results.

Commitment to Quality

Producing the very best instruments is not something we take lightly. Every instrument must pass customer specified test parameters. We inspect all xenon lamps and optical filter glass to strict quality specifications. The Ci4400 meets relevant CE, UL, CSA, ISO and EN safety and electrical standards for both machinery and laboratory test equipment.
