Angle & Slope Measurements

Shopping Options
We supply angle measurement tools for surveyors, engineers, contractors, installers, land managers and outdoor field teams who need to check slopes, gradients, inclines, level changes, direction and alignment. Our range covers practical instruments for quick hand-held checks as well as more controlled equipment for construction, installation, land work and professional angle measurement.
Whether you are checking the fall on a drainage run, setting an angle during installation, confirming the pitch of a surface or measuring direction in the field, the right instrument helps you work from a clear reading rather than visual judgement alone. Our range covers everything from simple tools for checking slopes and direction to digital instruments for level, pitch and alignment work, along with theodolites for more precise angle measurement on site.
Choosing Angle Measurement Tools for the Work
The best angle measurement tools depend on what needs to be checked and how the reading will be used. A quick slope check on a path, embankment or access route may require a different instrument from a detailed alignment check during steelwork, joinery, pipework or machinery installation. Likewise, a compass used for outdoor direction finding serves a different purpose from a theodolite used for controlled horizontal and vertical angle measurement.
Before choosing an instrument, consider the measurement range required, how clearly the reading needs to be displayed, whether the work involves repeated checks and the conditions in which the equipment will be used. Some users need simple slope measuring tools for occasional field checks, while others need a digital reading to support routine installation, maintenance or engineering work.
Clinometers for Slope, Height and Incline Checks
Clinometers are useful where the main task is checking incline, slope or height-related angles in the field. They are commonly used for land work, forestry, terrain checks, access routes and outdoor measurement where users need to understand how steep a surface or feature is before continuing with work.
A clinometer can help users assess gradients on banks, tracks, paths and uneven ground, or support angle-based height checks where the correct method is followed. The most suitable instrument depends on whether the work requires a simple visual reading, a digital display or additional functions for a particular field task. For equipment designed specifically for slope and height-related readings, explore our Clinometers range.
Inclinometers for Tilt and Gradient Measurement
Inclinometers are designed to help users check tilt, inclination and gradient. They can be useful when reviewing the angle of a surface, checking a route or confirming the position of installed components. In construction and maintenance work, they may support checks on pipework, access ramps, structural elements, machinery or ground features where the degree of incline matters.
A suitable inclinometer can provide a more practical alternative to estimating a slope by eye. It can also help teams repeat the same type of check across several locations. When choosing slope measuring tools, consider whether the task requires a digital display, a particular level of resolution or a compact unit that can be carried easily between work areas. For instruments focused on tilt, slope and inclination, browse our Inclinometers range.
Digital Levels and Digital Angle Measures for Alignment Work
Digital levels and angle-measuring equipment are useful where users need to check level, plumb, pitch or alignment during fitting, installation and maintenance work. These tools can support practical tasks such as checking timber, steelwork, pipework, machinery, fabricated components or installed fixtures before the job moves forward.
A digital angle measure is particularly useful when a displayed angle reading is needed rather than a simple bubble-level indication. It can help users set, transfer or verify an angle during installation work, especially where several components need to follow the same position or gradient. Digital levels may also be useful for repeated alignment checks where a visible reading helps teams work more consistently.
The functions available will vary between products, so it is important to check the individual specification before buying. For digital readings of level, pitch and angle, view our Digital Levels range. For equipment used to set, transfer and check angles during installation work, explore our Angle Measurement range.
Compasses for Direction Finding and Outdoor Navigation
Compasses remain useful for practical direction finding where users are working outdoors, reading maps or moving across unfamiliar land. They can help users identify direction, follow a route, confirm bearings and navigate between locations without relying solely on electronic devices.
This makes them useful for forestry, land management, environmental work, outdoor inspections, recreation and field activity where a simple, portable direction tool is required. The best compass will depend on how it will be carried, whether the user needs map-reading support and the level of visibility required in the field. Browse our Compasses range for practical direction finding, map work and outdoor navigation.
Theodolites for Precise Horizontal and Vertical Angles
For more specialised construction, engineering and survey work, theodolites provide a controlled way to measure horizontal and vertical angles. They are suited to work such as construction alignment, layout checks, vertical reference work and repeated site observations where a higher level of angular control is needed.
A theodolite is not a general-purpose slope tool. It is intended for professional angle measurement where a stable setup, careful levelling and correct use are essential. Users who need to check lines, confirm positions or support engineering layout should choose equipment based on the full site workflow rather than the instrument alone. For electronic instruments used for professional angle measurement and construction alignment, view our Theodolites range.
Using Angle and Slope Measurements on Site
Angle and slope measurements support many everyday field and construction tasks. Contractors may check drainage falls before pipework is installed. Landscapers and civil teams may review gradients on paths, ramps or access routes. Installers may use a digital angle measure to set a repeated angle during joinery, steelwork or fabrication. Maintenance teams may need to check the lean, tilt or alignment on installed equipment before making adjustments.
On land and outdoor sites, a gradient measuring tool can help users assess slopes before planning access, carrying out inspections or working across uneven ground. The right instrument should be chosen for the actual task. A simple tool may be suitable for a quick slope check, while more detailed angle measurement tools may be needed for alignment, installation or professional survey-related work.
