Feature

● Light intensity set digitally, real-time monitoring, closed-loop controlled and automatically adjust to meet the different standards (standard 420nm; 340nm, 300~400nm, 300~800nm is offered on request) 

● 10.4 inch large color touch panel, a variety of test monitoring modes (animation, digital, graphic) operate easily and clearly.

● All key components such as temp, and humidity sensors, ultrasonic himidifier are imported from USA, Japan, Germany, etc.

● Blackboard Thermometer (BPT), the Standard Blackboard Thermometer (BST), Irradiance detector and samples placed in the same position, a true reflection of the sample under test conditions, the data displayed as figures, charts, curves on the large color screen, no need to stop for observation. 

● Detection and wireless transmission using light energy conversion technologies for energy, not the other home power supply. 

● Sample holders can be timed independently to achieve different tests simultaneity in the same machine 

● Rated 2500W long arc xenon lamp simulate daylight spectrum. 

● Industrial temperature control (cooling) system offers quickly and smoothly control
