Write a review
This measuring instrument contains a small transparent vial partially filled with a usually yellow liquid. The liquid is often ethanol which does not freeze, even at low temperatures. An air bubble is located inside the vial. A spirit level has one or two tubes to measure horizontality or verticality. When the bubble is between the two lines, the level is perfect. The location of this air bubble is the main thing to check. It indicates whether the level is well positioned (flat or sloped). The spirit level is an essential tool for all the professionals in the building industry such as masons, carpenters, glaziers, etc. Designed specifically for professional use, the Ronix RH-9401 is powerful, durable, and intuitive.

Using the Ronix RH-9401 spirit level, you'll get perfect results, even if you're not a great handyman.
