Small radiation cover light blinds me

Small radiation cover (light blinds me) Description: Light reflected radiation thermometer screen to prevent direct solar radiation on the instrument (mostly built-in sensor) and the face of the instrument, to protect its internal instrument against strong winds, rain, snow, etc. impact. And its special surface treatment and design, the instrument sensing part proper ventilation, can really sense changes in the external air temperature and humidity, carbon dioxide and other environmental factors. Light thermometer screen (radiation shield) is fully in line with WMO standards. Large radiation shield standard 9-layer, 1,2,9 layer is solid, the other layer is hollow; small radiation shield standard 19-story, 2 layer is solid, the other is hollow with bending plate. Advantages: 1) can effectively block ultraviolet irradiation under natural conditions; 2) to prevent rapid aging instrumentation under harsh field conditions; 3) can reduce the measurement error caused due to a strong light; 4) small size, light weight, easy to install. Rationale: Light louver box (radiation shield), the use of cover the temperature uniformity and consistency with the outside air temperature, the sensor is completely surrounded by the inner and blocking radiant heat and precipitation. Natural ventilation by using insulation. It's on board for the umbrella, the middle ring multilayer sheet, following the radiation plate, the sensor is placed in the middle of the cover. When the temperature and humidity sensors installed inside the cover to prevent the thermometer bulb by direct solar radiation. Radiation stream flow sensor and its sides are kept in contact with the temperature and humidity inside the hood, can be very close to ambient air temperature and humidity.
