Photochemical Environmental Simulation Chamber

Main specifications

1.The reaction cavity has dimensions of 2100*6700 (diameter * length, unit: mm). The reactor device ensures airtightness, and the air leakage rate is less than 3% per hour.
2.The reactor is equipped with a pressure safety port, an air extraction port, nine air inlet ports, nine sampling ports, two temperature and humidity probes, two pressure sensors, etc. Relevant software is installed to achieve continuous monitoring and recording of the temperature, humidity and pressure in the reaction chamber, including curve graphs.
3.The reaction chamber should be equipped with an irradiation system to provide the necessary ultraviolet light for simulated reaction experiments, and both the wavelength band and the light irradiation intensity of the simulated light source inside the chamber are adjustable. The intensity of the simulated light source meets the index requirement of the photolysis rate range JN02 = 0 - 0.5/min⁻¹, with a central wavelength of 365nm, and it has the function of being replaceable and expandable according to experimental needs.
4.Temperature control: 10 - 40°C.
5.Humidity control: 5 - 90%.
6.Zero gas is provided, and the gas supply volume is 150 - 250 L/min.
7.The reaction chamber is equipped with an accurate gas mixing system.
8.The reaction chamber is equipped with a liquid sample gasification/heating system to inject non-gaseous reactants into the reaction chamber.
9.Reaction device: A Teflon membrane with a light transmittance of over 93% is used.
