Product Description The Sun Shine Recorder Optical, also known as the Campbell-Stokes Recorder, is a device used to measure sunshine duration. It's primarily a meteorological instrument used to record the number of hours of bright sunshine at a specific location. Here's a breakdown of the components and features you mentioned: Campbell-Stokes Recorder: The Campbell-Stokes Recorder is a type of sunshine recorder that uses a glass sphere (usually made of clear or optical glass) to focus sunlight onto a specially designed paper chart or strip. When the sun's rays pass through the glass sphere and concentrate on the chart, they can cause scorch marks or burns on the paper. These marks correspond to the hours of sunshine, and by analysing them, meteorologists can determine the duration of sunshine each day. One Year Chart Strips: This package includes one year's worth of chart strips. These are the special paper charts that you place under the glass sphere. As the sun moves across the sky each day, it burns marks on these charts, allowing you to track sunshine hours over time. Wooden Box: The wooden box serves as a protective and storage container for the Campbell-Stokes Recorder and the chart strips. It helps keep the instrument and supplies organized and in good condition when not in use. Vintage Style: The use of the term "vintage style" suggests that this TSA Sun Shine Recorder Optical is designed to resemble or replicate the appearance of older Campbell-Stokes recorders, giving it a nostalgic or antique aesthetic. This can be appealing to collectors or those who appreciate vintage instruments. The Campbell-Stokes Recorder is a traditional and somewhat historical instrument used in meteorology. While it provides a simple and effective way to measure sunshine duration, it has limitations compared to modern electronic instruments. It requires regular maintenance, chart replacement, and manual data reading and recording. Therefore, its use is often limited to educational purposes, historical climate data collection, or as a decorative item. If you're interested in tracking sunshine hours for practical purposes, modern electronic sunshine recorders are more convenient and accurate. However, if you appreciate the historical and aesthetic aspects of the Campbell-Stokes Recorder, it can be a unique addition to your collection or a decorative piece for your home or office.
