What's The Difference?: Inclinometer vs. Clinometer

A clinometer and an inclinometer both measure angles of inclination, but they are definitely not the same thing. The main difference between a clinometer and an inclinometer is the type of measurements they are used for.

A clinometer is a tool that measures vertical angles such as slopes, heights, steepness of ascents/descents, and azimuths. It typically consists of two arms attached to handles with a spirit level in between them which acts as the reference point for measuring levels of inclination.

An inclinometer is designed for measuring static angles, such as the tilt of surfaces and objects in various directions. It comprises an X-axis pointing from left to right & Y axis pointing from front to back on either side.

Each tool can be used similarly by off-road drivers. They can get hooked up and mounted on the vehicle to display the current angle incline of the terrain.

So while they may be slightly different for off-road driving purposes, they work the same.

How To Use An Off-Road Inclinometer

Follow these steps to use an off-road inclinometer. It’s a simple and easy device to use, but it must be properly set up to get the best and most accurate results.

Step One: Install & Mount The Device

First, we need to install and mount the device inside the vehicle. Park on a flat surface when doing this to properly stabilize the inclinometer. It can get a better reading this way.

Mount the inclinometer onto the vehicle using mounting hardware, ensuring it is securely affixed in place for optimal readings and safety. This may require drilling holes depending on where it gets mounted.

Depending on the device, it should include screws or some form of adhesive for mounting on the dashboard area.

Step Two:  Read & Review The Instructions

Always take time to read and review the instructions for an inclinometer device. They all have something unique - whether it is installation instructions or settings adjustments.

This will also make installing the device easier. For example, some inclinometers are multi-purpose devices with altimeter, compass, and barometer readings too.

Step Three: Test The Readings

Check the angles indicated by the off-road inclinometer at intervals throughout the ride in order to measure changes in elevation as they occur. This is the best way to test the readings in real time.

We can also make note of readings taken from stationary positions such as parked vehicles. This will help you get an idea of the current terrain before setting off on a journey and allow you to better plan ahead accordingly.

Step Four: Hit The Off-Road Trails

Once we feel like the inclinometer is working the way it should, we can finally head off adventuring on the trails with more confidence.

Do Off-Road Inclinometer Apps Work Well?

It’s important to differentiate a traditional inclinometer tool and an off-road device. They are much different in the way they function, but the goal is the same. To provide a proper reading of the terrain, slope, altitude, etc.

And with the advancement of mobile devices, we also can access inclinometer apps like this one. However, I was not impressed with the results while using it.

I found it to be inaccurate and unreliable. The data was incorrect and I was not getting proper readings fast enough while driving. It’s much easier to install one inside the vehicle because it works faster with more accuracy.
