The weather resistance test chamber for carbon arc lamps mainly uses solar-type carbon arc lamps as the light source. By changing the temperature (sample temperature, working chamber temperature), relative humidity, rainfall, etc., it simulates the comprehensive combination of light, heat, and water conditions of outdoor climate test chambers, and conducts artificial aging tests on the photochemical and mechanical properties of the tested materials.
Using PLC touch screen controller, the control is stable, and the main control parameters are light irradiance, working chamber temperature, sample rack temperature, and relative humidity, which can be automatically controlled by closed loop.
Carbon arc Lamp Weather Resistance Test Chamber
1300*1400*2050mm(The actual product shall prevail!)
Use light source
