Best Inclinometer

No matter whether you’re a carpenter, plumber or a DIY enthusiast; an inclinometer is a tool you should have in your arsenal. It’s an instrument that measures angles, and it can be used for various tasks, from checking the shelf’s level to set the angle on a miter saw. Here we will not only provide reviews but also give you a brief buying guide so that you can end up with an informed decision when purchasing an inclinometer.

So, an inclinometer is a useful instrument to measure the angles of slope, elevation, or depression concerning gravity. These angles can be measured in degrees or percent. When installing a pipe, conduit, floor, etc, an inclinometer can speed up your work. Buying an inclinometer is worth the money. This simple instrument has good applications in wide range of areas from construction and mining to health and safety.

There are two types of inclinometers, digital and analog. Digital inclinometers are more precise and easier to read than analog ones. They also have more features, such as storing data and calculating averages. Analog inclinometers are less expensive, can be used without batteries, and are perfect for working in remote places.

Buying Guide for Best Inclinometers

There are the things you should consider before purchasing an inclinometer.

1. Accuracy

We consider that accuracy is the most critical factor to consider when buying an inclinometer. Most inclinometers have an accuracy of +/- 0.05 degrees, but some can be as accurate as +/- 0.01 degrees. The more expensive models are usually more accurate. However, all that glitters is not gold, so instead of going for a blind purchase, check the reviews and compare before making the final decision.

2. Water Resistance

When we talk about water resistance, it is not only about the water but also the humidity, sweat, and even dust particles. If you’re going to use your inclinometer in wet conditions, make sure it’s water-resistant. The IP65 rating is the most secure you can get.

3. Battery Life

If you use your inclinometer in remote places, ensure its long battery life. Most inclinometers work on AA or AAA batteries, and the average battery life is around 70+ hours.

4. Display

What’s the aim of having an inclinometer if you can not read the measurements. So, consider the display before making your purchase. Most of the digital inclinometers have an LCD, which is easy to read. If you use your inclinometer in low-light conditions, make sure it has a backlit display. An upright display feature is also available on many inclinometers allowing you to see values from any angle.

5. Magnetic Option

Last but not least, consider the magnetic feature. If you’re going to use your inclinometer on a metal surface, make sure it has a strong magnet. This will help you attach the inclinometer on to the surface and take accurate reading. If inclinometer is too long/large for you, you can choose an angle cube. Angle cube is actually an inclinometer but has smaller size and square shape. It’s designed to stick on the saw blade and you can adjust the blade angle accordingly.


Inclinometers are extremely useful tools that can be used for a variety of purposes, from measuring the angle of a slope to monitoring the tilt and pitch of a car. In this article, we’ve reviewed ten of the best inclinometers on the market and their key features and specs.

So, whether your choice is analog or digital inclinometer, there’s sure to be one on this list that’s perfect for you. However, if you’re a plumber and still want a pin-pointed choice, then go for the Klein Tools 935DAGL inclinometer. And if you’re an off-roader, then the Autool Car Inclinometer Level Tilt Gauge  is the best inclinometer for you. With its built-in GPS and compass, it’s sure to help you find your way home.

Last but not least, choose an analog inclinometer for off-grid living or simply for a simple look, then go for the Johnson Level locator inclinometer.
