 3.5.Temperature control
 UV cycle
 First stage of photochemical reaction is not sensitive to temperature change. However, the subsequent second stage reaction rate closely relate to temperature. In general, with increasing temperature, the reaction is speed up. Therefore, in UV exposure test process, the temperature control becomes very important, more important is to match temperature in accelerating test to the practical maximum temperature which material will encounter in application. The temperature in the UV equipment can be set at any point from 50℃ to 70 ℃, depending on the illumination level and temperature of the indoor environment. The temperature control device is a micro-computer controller, which direct calculation function devices such as air heaters, water heaters, and a series of systems to complete.
 Moisture cycle
 As the temperature increased, humidity’s destructive power to material will increase dramatically. Therefore, in the process of moisture exposure, temperature control is a basic requirement. Furthermore, to produce acceleration effect, keeping high temperature is required in the process of moisture exposure. During condensation process in the device, temperature can be set at any point from 40℃ to 60 ℃.
 Heating system
 U-type titanium alloy high-speed electric heating tube;
 Independent temperature control system and lighting systems
 Temperature control and power output are all calculated by the microcomputer, to achieve high accuracy and high efficiency;
 With over heated protection function to the heating system;
 Heating and temperature to black aluminum plate is controlled by intelligent temperature controller  made in Korea, the output power calculated by microcomputer, PID self-tuning. The monitor is standard Pt-100 blackboard temperature sensor;
 Heating and temperature of water tanker is controlled by Korean “Knicks Alto” temperature controller.  The water tank locates in the lower position of chamber, with built-in electric heater. In the cycle test, a test section is a dark condensation process, it requires the inside cabinets can produce hot saturated steam. As the steam touch to the relatively cool surface of sample board, condensation occur.
