Laser Measurers

Point a laser to determine the distance to an object up to hundreds of feet away. These measurers show the distance on the LCD or viewfinder display.

LCD

Green Laser—Green lasers appear up to 10 times brighter than red lasers, so they’re easier to see outdoors, in bright lighting, and from far away.

Laser Targets—You’ll need a laser target (sold separately) to measure distances over 150 ft. or when shining the laser on an uneven, clear, or mirrored surface.

LCD with Backlight, Color Screen, and Touch Screen

Measurers with a color touch screen have a camera, so you can select your target on the screen. You can also magnify the image up to four times larger than its original size.

Cannot Be Sold To—Measurers that cannot be sold to the listed regions do not meet energy efficiency requirements.

Laser Targets—You’ll need a laser target (sold separately) to measure distances over 150 ft. or when shining the laser on an uneven, clear, or mirrored surface.

Measuring Wheels


Style A	Style B	Style C	Style D

Style E	Style F	Style G	Style H

Style J	Style K

Roll these wheels along a surface to measure long distances. Choose a wheel diameter of 11.5” or larger for uneven surfaces. Wheels with a diameter less than 11.5” are good for smooth, hard surfaces.

Analog Display—Wheels with an analog display don't rely on a power source to count, so they won't lose power while you're measuring. However, you can't change the display to different units of measure.

Digital Display—Wheels with a digital display give you the option to show measurements in inch or metric units. Because they run on batteries, they can lose power while measuring.

Steel Wheel—Steel wheels are the most durable wheels in our offering, so they stand up to rough terrain. Their added weight gives them stability, so they’re good at staying accurate on uneven surfaces.

Aluminum Wheel—Aluminum wheels are lightweight yet durable and can be used on rough terrain.

Plastic Wheel—Plastic wheels are lightweight and work best on smooth, hard surfaces.

Style K—Style K operates on a nonreplaceable battery with a minimum 10-year life.

Handle Display—Wheels with a display on the handle give you easy access to the digital counter and its controls to let you change the settings while you measure.

Wheel Display—Those with a display on the wheel keep both the wheel and counter in your line of sight, so you can guide and stop the wheel for an accurate measurement.

Folding Handle—Wheels with a folding handle can be folded up for portability and storage in small spaces.

Telescoping Handle—Wheels with a telescoping handle let you change the length of the handle. When set to shorter lengths, you can use them on elevated surfaces such as countertops.

Digital Flat-Material Measuring Wheels for Saws

Accurately cut 2×4s, boards, and other materials without the hassle of a tape measure or creating jigs as a stop. As you slide material along your saw fence, the digital counter measures its length, so you know what length you’re cutting. These measurers clamp onto most saw fences. Program the blade offset, including its angle, to account for the distance between the measurer and the blade, so you get an accurate measurement.

Distance-Measuring Modules for Development Boards

Stream distance readings to your development board in real time. Set up these modules near your robotics, production lines, or liquid monitoring systems to capture changing positioning.

Ultrasonic Modules

Ultrasonic modules use sound pulses to measure distance. They can be used in low lighting. However, they may not be accurate on soft, small, or oddly shaped objects that won’t reflect sound waves properly.

Infrared LED Modules


Wire Leads Connection	Qwiic Connection

Infrared LED modules bounce light off an object and back into their own sensor to measure distance.

I²C Communication Protocol—Modules with I²C protocol make setup and data collection simple. They convert readings into an electrical signal to transmit to your board.

Qwiic Connection—Those with a Qwiic connection are easily installed using Qwiic cords.

Digital Tape Measures

Image of Product. Front orientation. Tape Measure Blades.

Replacement Blades

Don’t let human error slow you down when reading and logging measurements. These tape measures instantly show your exact measurement on the display—no need to count hash marks. Toggle between inch and metric, convert fractions, find the center of workpieces, and record measurements to a screen on the handle, all with the click of a button. They’re also equipped with a laser to precisely align the blade, so you can trust your measurements are accurate every time.

To calculate, store, and share your measurements, these tape measures connect to an app via Bluetooth. They come with batteries, but you need an electrical cord and adapter (both sold separately) to charge them.

Automatic Blade Lock—Extend the blade and it locks in place automatically. These tape measures are especially useful for solo jobs since they free up your hands for other tasks.
