Dumpy Levels

  • Laser levels including Leica Laser Levels, line and dot laser, pipe laser and grade lasers.

    Dumpy levels, also known as automatic levels or site levels, are a tried and trusted member of any construction team.

    The Leica Jogger 24 and Leica Runner 24 dumpy levels are excellent budget levels that will perform a wide range of tasks to a high level.

    The Leica NA700 Series is an unstoppable level. These highly reliable levels can withstand drops to the ground, a fall into water as well as heavy vibrations from machinery; they will just keep on working!

    Feel free to call us on 0800 633 5131 if you have any questions.

  • What is a Dumpy Level?

    A dumpy level, sometimes called an automatic level or a site level, is an optical instrument used to set horizontal levels.

    The operator must look through the optical eyepiece to measure against a staff or tape measure placed at the point being measured. This site leveling technique is particularly useful to surveyors during site surveys as well as a whole host of other uses within the construction industry.

    When operating a dumpy level you must ensure that the level is securely placed, preferably on a tripod, and that the pond bubble is level. This can be adjusted using the leveling screws. Next you must sight the instrument by looking through the eyepiece and focusing on the staff or tape measure at your chosen point of measurement.

    A decent dumpy level should auto-level to a certain degree although it is worth checking the instrument to see that this is working as expected.

    Our recommended dumpy levels are the Leica NA700 Range which offers high performance at an affordable price. Different magnification levels are available throughout the range to cater for your exact needs.
