Product: TR-74Ui, Field: Function Introduction The Japanese TandD temperature and humidity logger features low power consumption and high accuracy, making it a reliable environmental recorder. The TR-74Ui can simultaneously measure temperature, humidity, illuminance, and ultraviolet (UV), and can store up to 8,000 data points. Afterwards, you can download the data to a computer via USB for viewing. The instrument also displays the accumulated UV and illuminance totals directly on the device, so there is no need to download via software to obtain statistics. This is an image showcasing a modern art gallery, featuring an exhibition on brightness and UV management. The gallery uses large-area UV-filtering glass windows and strategically placed LED lighting to protect artworks, along with informational display boards explaining the importance of light management in preserving art pieces. Part of the gallery includes a greenhouse area, demonstrating the application of natural light management in maintaining plant health. The entire space is clean and modern, filled with visitors who are viewing the artworks and greenhouse plants.
