About the Thermometer Heat Lines black outline icon

A slim thermometer stands upright with a rounded bulb at the base and a narrow column rising through the stem, while five short lines step down the right side to signal radiating heat. It reads instantly as temperature, warmth and fever, so it suits forecast widgets, smart-home climate controls, HVAC service pages, health tracking apps and lab or food-safety slides.

The stem runs roughly twice the height of the bulb, and the evenly spaced heat lines shorten toward the top to balance the tall silhouette. Pair it with sun, humidity and snowflake icons in a weather set, and keep it at 24 px or larger so the thin inner column stays visible.

This is the black outline version of the thermometer heat lines icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
