Product Information
Transit levels are built differently than the usual level. As an optical instrument, this device has a built-in spirit level that makes it capable to be mounted on a tripod. Although mainly used for surveying and building, transit levels are also used to help determine the relative position of lines and objects. For a reliable transit level, choose the Northwest Instrument Siteline Transit Level NSL500B.
This inexpensive but accurate and easy-to-use transit level is designed to be used for different leveling applications in surveying or construction. The instrument has also been designed to be so durable that it can withstand the rigors of daily usage in any work site.
The transit level from Northwest Instrument is ideal for light construction leveling applications, including foundations, patios, decks, plumb walls or turn angles, streets, curbs, or landscaping. The instrument is also good for use with running straight lines or grading applications. There’s definitely no need to spend for extra leveling equipment when this transit level is so versatile for different applications.
When it comes to searching for a durable and accurate transit level, the Northwest Instrument Siteline Transit Level NSL500B is the right choice. Make sure to buy products by NWI from authorized distributors, dealers, and resellers, like Engineer Warehouse.
