■ *Black ■ Blue ■ Orange ■ White

*Respresentative of approximate test specimen color

Note: Black Panel temperature in the fluorescent device is achieved only by heating the chamber air (no IR). Thus, all specimens are heated

equally, without regard to color. Because xenon light is a full spectrum

light source like natural light, sample temperatures vary by color, as in

natural sunlight.

Rotating Sample Rack-

The rotating rack delivers the best exposure uniformity

■ Samples are rotated continuously during test. No need to manually rotate test samples

■ Uniform specimen and chamber temperature, RH, irradiance and spray

■ Allows for even and consistent airflow

over sample surfaces

■ Can accommodate three dimensional samples

- Finished Products

- Bottles

Recalibration on the Web

You can now process the return of your calibrated lamps for recalibration via the internet. This service is intended to reduce turn around time and better facilitate your recalibration request. Visit us at www.atlas-mts.com/recalibration.

Intelligent Controlled Irradiance (Ci) System

A closed loop system automatically adjusts lamp output in real-time delivering the most stable radiant exposure

■ Narrow band (340 nm or 420 nm), broad band (300-400 nm) or illuminance control/Lux (400-750 nm)

■ Irradiance defined by user during test programming or by factory

programmed test methods

■ Intelligent control will only allow

the user to select an irradiance that matches the defined test method

■ Wattage regulating system
