Digital Protractors with Level and Laser

A dot laser extends the working distance 200 feet beyond the tool length. This tool has two digital displays that invert when turned upside down; one shows the base angle and the other shows the moveable arm angle. It also has a lock to hold the arm in position, a hold button that freezes the display, auto shutoff, and 1/4"-20 threads for connecting to a tripod.

Multi-Axis Levels

Simultaneously check if a surface is level horizontally and vertically, as well as front-to-back. Use one of the three main vials on these levels to determine if your surface is completely flat, upright, or at a 45° angle. Plug in the fourth vial to level two axes at the same time. Use them to level cross-sections of pipe, frames, and other three-dimensional parts.

Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Pitch-Measuring Levels—Level and determine pitch with one tool. The horizontal vial has incremental marks that indicate the incline of surfaces such as drainage pipes, conveyor chutes, and roofs.

Magnetic Levels—Stick to metal surfaces for hands-free leveling.

Low-Light Levels for Tight Spaces

Level surfaces inside machinery, behind equipment, or anywhere too cramped for light to reach. The vials on these levels illuminate for clear reading without a flashlight. Also known as torpedo levels, their compact size and tapered ends make them ideal when you're leveling short surfaces or working in tight corners. Rest these levels on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Pitch-Measuring Levels with LED Vials—Use the incremental marks on the horizontal vial to find the incline of surfaces while you level. LED lights illuminate one vial at a time, so you can read it clearly without the other lights creating glare.

Two-Axis Surface-Mount Levels

Mount these levels to workbenches, platforms, and tabletops to keep them horizontally level in two directions. Use them to make sure surfaces stay aligned over time.

Screw-On Levels—Fasten these levels to any drillable surface for the most secure mount that won't shake loose, even on vibrating equipment. Fasteners are not included.

Meters for Solar Power Systems

Find the best spot for new solar panels or check the performance of existing ones. These tools measure solar power in different ways, helping you comply with IEC 62446-1, a standard for testing, documenting, and maintaining solar panels connected to the grid. The data hold function freezes a measurement on the screen, so you have time to write it down. CE marked, all meet European safety standards.

Solar Irradiance Meters

Solar irradiance meters measure electromagnetic radiation, giving you a more precise sense of how much power a solar panel will generate than solar light meters. These meters also have two options for checking how heat affects your solar panel: a built-in temperature sensor and, for higher accuracy, a temperature probe. The integrated angle indicator and compass help you find the perfect tilt and orientation for your panels. Connect these meters to your smartphone via Bluetooth to easily store and share test results.

Solar Irradiance Meter Kits

Solar irradiance meter kits include tools to measure current and voltage, so you can check if your panels are generating the expected power. To test current, position your panel’s wiring within the jaws of the clamp meter. Or, if your wiring is hard to reach or clamp around, attach the flexible AC probe to the clamp meter and loop it around your wiring. Neither method will interrupt your circuit, making frequent measurements possible. To measure voltage, wire the clamp meter’s test leads to your solar panel or power station.

Digital Horizontal-Plane Angle Indicators

Check the angle of your horizontal surface side-to-side and front-to-back. These indicators have a highly accurate sensor and precision ground stainless steel base. The LCD display shows slope, level, and angle in numerical values along with an image of a manual angle indicator. If you flip them so the LCD display is upright, they’ll automatically switch from checking two angles to check a single angle on a horizontal or vertical surface. They come with cable and a wall plug adapter for charging.

Because it’s stainless steel, the base makes these indicators a durable choice for industrial applications where plastic-bodied indicators would be too fragile. Mount them to equipment, even if it’s vibrating, to repeatedly check angles. A V-groove provides stability on curved surfaces.

Digital Angle Indicators

These angle indicators display highly accurate angle, level, and tilt measurements. They come set at true 0°, but you can choose an alternate zero point with the push of a button. Another button will freeze the reading on the display. Indicators have machined leveling surfaces, a V-groove for stability on curved surfaces, and two 6-32 threaded holes for mounting.

Digital Precision Levels

You won’t need to choose between precision or convenience with these levels. Their highly sensitive sensor accurately determines level, even when placed on vibrating machinery and equipment. Clearly read the high-contrast display in any lighting conditions – no need to squint to read vials. They stabilize in five seconds after you position them, so you can quickly check the alignment of one part and move on to the next item. You can also view the angle and slope of a surface without a separate tool. When you need to use these levels under machines or in tight spaces between parts, connect them to your smart device via Bluetooth. The free app lets multiple users view readings remotely.

In addition, the V-shaped indentation on the base means you can rest them on flat and curved surfaces alike. These levels also have a false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces.

Granite Base—Granite chips off instead of denting or deforming when dropped. It also won’t corrode in wet environments like cast iron or steel, so the base always stays accurate.

Levels for Tight Spaces

Levels

Squeeze these levels into places a standard level would never fit. Their short length and tapered ends make them ideal when you're leveling small parts or working in tight corners. Also known as torpedo levels, they're commonly used by plumbers leveling drains under sinks or by electricians installing components behind electrical panels. Rest them on flat surfaces or fit the side with the V-shaped indentation around pipes and curved shafts.

Heavy Duty Levels

These sturdy levels last longer than typical levels, even if you use them frequently. With four solid sides that form a box shape, they stay flat on surfaces without wobbling and won’t twist or deform over time. The aluminum housing and durable plastic vial won't crack if you step on them or drop them off a ladder or tool tray.

Digital Levels

Pick these digital levels for repeat leveling tasks and tired eyes. With a digital display for clear reading and an audio alert that sounds when your surface is perfectly level horizontally or vertically, you can quickly align a workpiece before moving on to the next surface. The false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces. You can also view the angle, pitch, or slope of a surface without a separate tool. Use the horizontal and vertical bubble vials on these levels to recalibrate the sensor if needed and as a backup option if your level runs out of battery.
