Atmospheric greenhouse gas simulation calibration warehouse

This equipment is to study the transmittance change of the incident calibration light source after the absorption of greenhouse gases. It can input different ratio of greenhouse gases and create conditions for detecting the influence of different concentration ratio of greenhouse gases on light wave transmission. In addition, the device can simulate different cold and hot gas environment, and can effectively control, monitor and record the temperature and vacuum in different pressure space.
