What Is A Rotary Laser Level?

Last Updated On December 6, 2021 By Elliot

A rotary laser level is used to measure horizontal and vertical angles. The device has a small motor that spins a mirror at high speed.

When looking through the device, the rotating mirror reflects light from a laser source onto the object to be measured.

The reflected light is then captured by the device’s sensor. The angle between the surface of the object and the sensor determines the height of the object.

This laser detector provides correct measurements for outdoor projects. it can also measure the level surface for any kinds of remodeling projects.

This rotating laser are very reliable rotating lasers and they have been tested in many different conditions.

They provide accurate readings even when there is no direct line-of-sight with the target. This makes them ideal for use on uneven surfaces such as roofs or walls.

Rotating laser levels: What you need to know

There are two main types of rotating laser levels available today. These include handheld units and fixed mount models. Each type offers its own advantages and disadvantages.

High-performance, low-cost rotary laser level, Handheld units offer excellent accuracy but require frequent recalibration due to their limited battery life. They may not work well if your project site is too far away from an electrical outlet.

Fixed-mount Rotary Laser Levels Fixed-mount devices do not move around during operation.

However, these tools tend to cost more than handheld versions because they must incorporate additional features like mounting hardware and software.

The laser diode of the rotary laser tool are usually mounted inside the housing so that the beam does not get interrupted while measuring.

These tools are typically designed for indoor applications only. If you plan to install one outdoors, make sure it will withstand extreme weather conditions.

How to choose a good rotary laser level?

Choosing a suitable model depends largely upon what kind of job you want to perform. For example, if you are installing new drywall, you should look for a unit that measures both horizontally and vertically.

The rotary laser level rotation must be precise enough to ensure that all seams meet up perfectly. You don't want to cut corners here!

If you're working on a roofing project, you'll probably want to find a product that's capable of measuring over long distances.

You might consider using a handheld version instead of a fixed-mounted model if you expect to travel frequently.

In addition to being able to accurately measure large areas, some models come equipped with other useful functions including tilt compensation and automatic leveling. 

How does a rotary laser level work?

The rotary laser level working range is determined by how much power the laser has. Most manufacturers recommend at least 1 watt per meter.

A higher output means better performance. However, this comes at a price. A lower output requires longer batteries which could result in less time before needing recharging.

Most models feature a built-in rechargeable lithium ion battery pack. Some models allow users to replace the internal battery without having to remove the entire unit.

Auto-leveling rotary laser for construction projects

This superb laser level package are very accurate in distance measuring and distance leveling. Self-leveling laser is one of the advanced laser level, They commonly used in construction projects and can help save lots of labor hours.

The self-leveling laser level uses the principle of triangulation technology to achieve high precision measurement. It consists of three parts: base station, receiver and transmitter.

Base Station connects to computer via USB cable or wireless network. Receiver receives signal from transmitter and sends data back to base station through Bluetooth connection.

Transmitter converts digital signals into analog ones then transmits them to receiver. This process makes the whole system works automatically.

Manual rotary laser level

Manual rotary laser level is also an a outstanding laser used in many indoor projects. You just have to control the angle manually.

The main function of manual rotary laser level is to provide more flexibility when doing measurements.

It’s easy to use because there is no need to calibrate the device. Just set the desired height and rotate until the red light turns off.

It also provides accurate measurements of vertical plane and horizontal planes. Manual rotary laser are widely used in building sites where accuracy matters most.

Manual leveling do have proper procedure to follow:

  • The first step is to align the laser beam perpendicular to the surface.
  • Then adjust the laser head so it touches the surface.
  • Finally move away from the surface while keeping the laser beam parallel to the ground.

What are other best types of laser levels?

There are many types of laser levels used in construction industry, such as hand held, tripod mounted, portable, etc.

The following is a list of best laser :

  • Auto lasers

The auto lasers is a type of handheld laser that measures distances using the principles of trigonometry. The auto laser features include:

Self-calibration – Auto calibration ensures that you get consistent results every time you make a measurement.

Tilt Compensation – Tilt compensates for any slight changes in your position relative to the target object.

Automatic Leveling – Automatic leveling allows you to quickly and easily check whether the laser line is perfectly aligned horizontally or vertically.

  • Portable Laser Levels

This portable laser level has been designed with ease of operation in mind. With its compact size, this model will fit comfortably on your workbench or toolbox.

With its unique design, this laser level offers superior performance at a great price point. Its lightweight aluminum housing is durable enough to withstand years of heavy duty usage.

  • 360-degree spinning laser beam

This type of laser pointer are often called “spinning laser pointers” due to their 360 degree rotating beams. These devices offer excellent visibility and range capabilities.

They come equipped with powerful LED lights which allow users to see clearly even under low ambient lighting conditions.

These laser pointers are ideal for outdoor applications like surveying, mapping, landscaping, and general site marking.

  • Dual grade lasers

This expensive laser level are commonly used for measuring large structures. It can be used indoors or outdoors.

Dual grade lasers feature two different wavelengths allowing you to measure both surfaces simultaneously.

  • Five-point self-leveling laser

This versatile tools are very useful for checking the alignment of walls, floors, ceilings, and roofs. They are perfect for interior and exterior jobs alike.

Laser are available in various sizes and shapes. Some models may require additional accessories depending on how they are being used.

  • Grade lasers pipe lasers

This recommended pipe laser is one of the best choices when working around pipes. This device comes with an adjustable height stand and a clamp base.

Pipe lasers are easy to use and provide reliable readings.

  • Green beam laser level

This variety of laser levels is made up of green light instead of red. Green light is more visible than red light.

It also provides better contrast between the laser beam and background objects.

  • Red laser level

A red laser level is another popular choice among professionals who need accurate measurements. Red laser levels have high accuracy and precision.

Some models are capable of reading gradations down to 0.1 mm.

  • Dot lasers grade lasers

This dot laser has a built-in scale so it can read from 1mm all the way down to 0.01mm. Dot lasers are suitable for indoor as well as outdoor projects.

  • Fiber optic laser level

This fiber optic laser level uses optical fibers to transmit the laser signal. Fiber optics are much stronger than conventional cables.

Optical fibers do not conduct electricity making them safe to handle during construction activities.


Laser levels are very useful tools for contractors who want to ensure they are working within safety guidelines. They help prevent accidents by ensuring workers stay safe during all phases of construction.

If you're looking for a quality laser level that won't break the bank then look no further! We've got what it takes to get the job done right.
