1. Large screen colour touch screen control, built-in a variety of test standards, can simulate the sun, rain and other test modes, a variety of test monitoring mode, intuitive display, easy to operate; 2. Irradiance self-calibration system, standard calibration xenon lamps, can be real-time calibration of irradiance, to ensure that the stability of the test; 3. Multi-channel irradiance sensors, the use of digital closed-loop control system, the power of the irradiance automatic compensation function, to achieve fully automatic digital control of irradiance; 4. Blackboard thermometer powered by solar batteries, wireless radio frequency transmission technology, to ensure stable control of the blackboard (black label temperature and convenient replacement; 5. The blackboard thermometer adopts solar battery power supply and wireless radio frequency transmission technology, which ensures the stability of blackboard (black mark) temperature control and convenient replacement; 5. The circulatory system of the test chamber adopts German ebm fan, Delta frequency converter and ultrasonic humidifier, which can accurately realise the control of temperature and humidity of the test chamber and the controllability of surface temperature of the blackboard thermometer and the specimen to ensure the stability of the test conditions; 6. 6 xenon lamp cooling system using Taiwan high-speed blower fan, built-in real-time monitoring system of wind volume, the xenon lamp can be overheating real-time protection; 7 instrument can be directly connected to municipal water, standard with a core filter water purifier, filter replacement is fast and convenient; 8 with multi-point monitoring system, can achieve real-time monitoring of xenon lamp voltage and current, water level is too low, the test chamber temperature is too high automatic shutdown protection function; 9. Germany Mueller electrical power supply safety protection of the machine, Japan's Omron power failure delay trigger device for the restart of the xenon lamp protection, comprehensive protection of the instrument's safe and stable work;
