UV WEATHERING TEST CHAMBER

GENERAL INTRODUCTION--UV WEATHERING TEST CHAMBER

to simulate UV-spectrum that similar to sunlight and integrate with temperature & humidity comprehensive test;

Employs programmable controller to set testing cycle that based on reliable UV light source to reproduce natural sun radiation;

Advanced temperature control system designed with PLC & Text as well as A/D modular to implement temperature and humidity
Control;

Humidity supply system consists of water sink, humidification system and by such a condensation mechanism to expose test
Specimen in a environment with humidity and UV light;

Protective system with functions such as altering signal for water shortage,over-temperature,short circuit,over-load with control
System located on control panel & in electrical cabinet thus to guarantee whole UV aging test process.

FUNCTIONAL FEATURES--UV WEATHERING TEST CHAMBER

Corrosion-resistance metal material SUS Stainless steel is introduced for internal & external testing chamber to provide an reliable
UV testing zone. UV accelerating aging test chamber includes 8 pcs of UV lamps for UV light source, water container, testing
Specimen holder as well as temperature, testing cycle control and display; 

Each UV lamp with power at 40W & its length at 1200mm to provide UV light for testing zone at 900 210mm. 4 pcs UV lamps is
Arranged as one row, total two rows are designed with lamp central distance at 70 mm; 

Testing specimen is designed to locate an surface with a distance at 50mm from UV lamp. Internal wall of test chamber includes test
Specimens & specimen holder, its opposite side is exposed into a space with cool air. Because of temperature differences,
Condensation will be generated onto surface to test specimen, meanwhile, free air convection can be assured via external wall of
Bottom test chamber as well as test specimen channel. 

Temperature of UV Accelerating Test Chamber is measured through Black Board with its size of width at 75mm, height of 100mm &
Thickness at 2.5mm. this black board is placed and exposed in testing central zone. the thermometer with its measurement range
from 30 to 80 Centigrade with accuracy at1 Centigrade. Independent control is designed for UV light as well as condensation
while condensation controlled through heating water.
