Thermometer Illustration - Visual Indicator of Temperature Level #3636968 (License: Personal Use)

This vector-style illustration depicts a classic analog thermometer with a white glass tube, gray calibration markings, and a vivid red liquid column indicating a mid-to-high temperature reading. The bulb at the base contains the reservoir of red fluid, which expands upward through the narrow capillary as temperature increases. The design is clean, scalable, and universally recognizable for conveying thermal data or metaphorical progress.

Commonly used in educational materials, weather dashboards, health infographics (e.g., fever charts), or fundraising progress trackers (e.g., “temperature gauge” for donations). Matches user intent for visual explanation of measurement, escalation, or status.
