This Higrometr icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The icon is shaped like a tear drop with the bottom half of it covered in dots. To the left of the tear drop shape is a vertical line with 7 smaller connecting horizontal lines facing left. The top, middle and, bottom lines are slightly bigger than the others.
