Additional information
Monitoring of atmospheric parameters: air temperature, relative humidity, solar irradiance, precipitation, wind speed and direction, time of wetness, with data collection every 10 seconds and storage every 60 minutes. Chloride deposition rate is evaluated by the wet candle method and sulfur dioxide deposition rate on lead dioxide sulfation plates (ISO 9225). The evaluation of the sulfur dioxide content in the atmosphere using a sensor is under development with data collection and storage, similarly to other parameters. Materials usually exposed: reference panels of different materials/metals, samples with organic coating, absorbers and reflectors surfaces, thermal solar collectors, polymeric materials, natural materials (e.g. wood), etc. Costs: Cost depends on samples dimensions and exposure time. Cost upon request.
