About the Thermometer Heat Lines black filled 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 solid black filled version of the thermometer heat lines icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
