The Ci4000 Offers Thorough ClimateControl to Best Replicate Your
Materials’ End Use Environment Consistent,Controlled Temperature Delivers Repeatable and Reproducible Results
Smart Damper
™ Balances test chamber temperature, BPT or BST and humidity levels and compensates for changes in ambient laboratory conditions Recirculates chamber air, introduces ambient air or a combination of the two
Precise Humidity control ASTM Black Panel Thermometer (BPT) or ISO/DINBlack Standard Thermometer (BST)
The electronic sensor provides direct and accurate
measurements of relative humidity and enables automatic control at the specimen level Controls and monitors temperature at specimenlevel to ensure test repeatability Control of one sensor type while simultaneously
monitoring the other 10% RH to 75% RH in light cycles*
BPT/BST Temperature vs.Chamber Temperature (CHT) Simultaneous Control of BPT/BST and CHT
Up to 100% in dark cycles* BPT and BST sensors simulate an estimate of the maximum temperature on a sample’s surface Advanced PID algorithms allow for discrete manipulation of test parameters
* Dependent on other parameters such as lamp power, chamber temperature, ambient lab conditions etc. CHT measures the temperature of the air
circulating within the chamber Smart Damper, variable speed blower and chamber heater are independently controlled Controlling both sample and air temperature
delivers maximum uniformity and can closely match the samples end use environment Instrument performance envelope is optimized allowing maximum flexibility in custom test applications

Black Panel Temperature Control Performance
The specimen spray applies water to the exposed surface of the sample which simulates rain to induce temperature shock and erosion effects Operable ranges of temperature control at various
irradiance levels (under normal laboratory conditions).
