What is the role of a humidity gauge in an ice rink?

The role of a humidity gauge in an ice rink is essential for maintaining optimal ice conditions. High humidity can lead to issues such as soft ice, increased surface water, and potential flooding, ultimately affecting the quality of ice for skating events and recreational use. By monitoring and controlling humidity levels, rink operators can take necessary actions to adjust the environment, such as using dehumidifiers or adjusting ventilation systems. This ensures the ice remains at the best possible quality for skaters, improving both safety and performance.

The other options relate to different aspects of ice rink management. Measuring the temperature of the ice surface is important for understanding its hardness and condition, while tracking the number of skaters is relevant for operational management but does not directly influence ice conditions. Measuring the thickness of the ice is also crucial for safety and maintenance but again, doesn't involve humidity management. The humidity gauge specifically focuses on environmental conditions that directly impact the ice surface and skater experience.
