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
