The spirit level is a measuring instrument§✘ that uses the principle o↓±☆δf liquid level to directly display •  the angular displacement with a±≥ε level bubble to measure th≠ ✔e relative horizontal position, vertic±±₹≠al position, and tilt position of↑ε↓★ the measured surface.

This level can be used for short-distance measure€φment as well as long-dista¶$nce measurement. It also solves the shortcomings ☆♣≠that the existing le©®γvel can only measure in open areas and is diffi←&cult to measure in narrow ≥​>↔places. It has accurate measurement, l∏≈λow cost, easy to carry, and economical. ∞★πBe applicable.

The spirit level is mainly‌ελ≈ used to detect or measure the l₽£≥↔evel and verticality. It can be divided into alγ¶uminum alloy square tube type, I-shaped, die-cast€$ing type, plastic type, special-shaped and other≠α∏' specifications; the length is fσ≠rom 10CM to 250CM and many specifications; The st$×raightness of the material and the qualit‌ y of the level bubble determine ™‍↑the accuracy and stability ofβ↔ the level.
