Home improvement measuring tools designed for reliable, repeatable levelling deliver straight results for shelving, tiling and joinery. Confident finishes reduce rework and save time for keen DIYers and tradespeople. Is Hultafors SM40 Spirit Level the accurate, durable choice for everyday site and workshop use?
⚡ At a Glance
- • Accuracy: 200 mm vial radius yields 10 mm/m sensitivity; tolerance ±0.75 mm/m normal, ±1.0 mm/m upside down
- • Best for: DIY enthusiasts and tradespeople needing quick, repeatable levelling on typical projects
- • Not ideal for: Precision metrology or laboratory measurements requiring sub-millimetre tolerances
40 cm aluminium spirit level with a 200 mm vial radius and a sensitivity of 10 mm/m. Tolerance is ±0.75 mm/m in the normal position and ±1.0 mm/m when turned upside down.
Quick, legible readings – thanks to the 200 mm radius bubble vial
A larger vial radius increases the arc travelled by the bubble for a given angle, producing a sensitivity of 10 mm per metre and clearer bubble movement. The stated tolerances of ±0.75 mm/m (normal) and ±1.0 mm/m (upside down) define expected accuracy under typical use.
Faster alignment when hanging shelves or fitting tiles, as bubble shifts are easier to judge. Clear vials reduce eye strain and speed up repeated checks.
Durable finish for site use – with anodised aluminium construction
Anodising adds a hard, corrosion-resistant layer to aluminium, helping the surface repel cement and other site contaminants. Lightweight aluminium gives strength without excess mass, supporting daily handling on site.
Surfaces wipe clean after contact with mortar or dust, keeping markings legible and extending usable life. Robust construction means the tool copes with regular workshop and site conditions.
Portable and easy to handle – with a 40 cm aluminium profile
A 40 cm length strikes a balance between reach and manoeuvrability, while aluminium construction keeps the profile light yet stiff enough for straight-edge tasks. Compact form helps when working in tight spaces.
Easier to carry between jobs and simple to position in confined areas such as behind radiators or inside cupboards. Practical size for common household and trade installations.
