XCH-TPS Photostability Test Chamber is equipped with visible light and near-ultraviolet lamp tube, which can independently control the type of light source, and can print and record visible light illumination and near-ultraviolet radiation in real time. Visible light and near-ultraviolet can be directly set, automatically adjusted and precisely controlled. Model: 150TPS~500TPS TEMP Range: 15~50℃ Fluctuation: ＜±0.5℃ TEMP Deviation: ＜ ±2.0℃(SAME LEVEL) Light Range: Visible light range: 100 ~ 8000LUX  Total illumination should not be less than 1.2 x 10^6Lux·hr UV range: NUV range: 0.84 ~ 5w/m squared The near-UV energy is no less than 200w•hr/㎡ UV wavelength: NUV wavelength: 320 ~ 400nm;
