VLTS is a device used in refrigerated road vehicles and cold storage facilities to monitor environmental conditions. It combines data logging from temperature sensors, humidity sensors, and analog sensors. The data can be stored on internal memory, a USB memory stick, or an SD card, and it can also be printed or sent to a server. Users can log in to a web application to view the status and data of each VLTS unit. Additionally, the VLTS supports GPS, allowing users to see the position of each unit on a map within the web application.
