Glow-in-the-Dark Magnetic Pocket Levels

Check the positioning of your equipment in dimly lit areas—the vial on these magnetic levels glows in the dark for easy reading. Sized to fit in your pocket, they’re easy to take on the go. The neodymium magnet, a rare earth magnet known for its strong hold, keeps these levels secure even on vibrating machinery. A V-groove provides stability on curved surfaces. Their plastic housing shields them from impact, so they won’t break if you drop them.

Levels for Long Distances

One person is all you need to determine level around corners and over long distances. Mount this level with the tubing installed at your desired height. Fill the other end of the tubing with water and raise it until the electronic sensor buzzes, marking the matching level point. Add more tubing (sold separately) to find a level point up to 100 feet away.

Glass with a Red Line

Replace existing gauge glass or combine with valves and guard rods to build your own level indicator. Cut to size with a glass tube cutter (not included).

Glass with a red line emphasizes the liquid level so it’s easier to read.
