2.Test chamber
The front door is installed with a window and a movable opaque screen that can block the window, the bottom of the square box is installed with blasting aluminum foil to prevent overpressure, and the top is installed with an internal pressure regulating device of the box.
Inner dimension: height 914±3mm, width 914±3mm, depth 610±3mm;External dimension: 1680mm high, 1450mm wide, 850mm deep (this size is for reference only)
Material: 1.5mm steel plate, baked white electrostatic paint outside, baked black paint inside.
Two, photoelectric measurement system:
1. Light source: 6.5V incandescent lamp with optical wavelength of 400~750nm
2, Receiving device: for silicon photocell, transmittance 0% for no light through, transmittance 100% light without blocking completely through.
