Safety Features

With Northwest Instrument, you can expect high-quality and durable products that meet expert standards every time. The Northwest Instrument Siteline Level Package comes with an IP54 rating, which means the equipment is protected from dust and water—two things you might encounter when you’re doing surveying projects in the field.

Aside from this, the hard carrying case is spacious enough to safeguard five pieces of equipment without leaving any wiggle room for them to bump into each other inside the case and possibly break. The hard case also comes with a lock to keep everything secure even in transit.

Best Ways to Use the Product

Make the most of your SiteLine Level Package when you apply best practices to your regular use. To start, you should double check that the siteline level is level throughout the horizontal 360-degree angle, otherwise, the measurements you will capture will be inaccurate.

Also, as you are adjusting the levels, turn both screws at the same time to avoid damaging the product. When you screw them on too tight, you won’t get the correct measurements. Aside from that, having the screws extra tight may warp the base plate and cause permanent damage to your equipment.

When you are looking through the lens of the product, there’s no need to squint or close your eyes. Doing so will tire your eyes, and you might distort your view which will result in inaccurate readings and reports.

Why You Should Buy

If you are someone who regularly does site and area measurements for your projects, you have to get the Northwest Instrument Siteline Level Package - NSLP100B. It is a certified asset as it will help you get correct and accurate measurements. This siteline level was designed to deliver precision—and that’s what you deserve for your home, yard, or commercial building site.

Despite other instruments being available in the market, this set of five tools is such a good deal that it’s practically a steal. There’s no need to find matching pieces from separate brands. You have your siteline level, multi-layer lens, tripod, plumb bob, and grade rod to complete your tool kit.
