SOLA spirit levels stand for maximum measuring accuracy, user-friendliness and robust construction – all specially developed for professional use on the construction site. In the Karl Dahm online shop, tilers and tradespeople will find a carefully selected range of these quality tools tailored to the real-world demands of construction work.


Whether aligning tiles, installing sanitary fixtures or adjusting building components – SOLA spirit levels deliver reliable precision and efficient workflows. With innovative features such as the patented FOCUS vial and ergonomic aluminium profiles, these levels are an essential tool for professionals.
In the daily work of tilers, dryliners, plumbers and other trades, the end result often depends on the smallest dimensional tolerances. Even minor inaccuracies can lead to major issues when laying large-format tiles or fitting sensitive components. A precise and reliable spirit level is therefore essential – it is the benchmark on any job site.
With SOLA spirit levels, you choose tools that perform reliably even under extreme conditions – whether in heat, cold or poor visibility. They truly prove their strength in renovation work, where elements often need to be retrofitted and realigned.
A key feature of SOLA spirit levels is the FOCUS vial – a development specifically optimised for tradespeople. This vial offers:
The FOCUS vial is also UV-resistant and thermo-resistant, making it a durable and reliable partner on the construction site. The clear bubble guide ensures intuitive reading even in low light or direct sunlight – reducing errors and increasing efficiency at every stage.
SOLA spirit levels are made from high-quality aluminium profiles that are lightweight yet exceptionally durable. The ergonomic design fits perfectly in the hand, while the balanced weight allows for easy overhead work.
Thanks to scratch-resistant surfaces, shockproof end caps and precision-milled measuring surfaces, these spirit levels can withstand the harsh conditions of the job site for many years. The shock-absorbing caps protect the ends from impact damage, preserving measuring accuracy. These models are particularly suitable for demanding applications in structural engineering or outdoor installations.
Karl Dahm offers SOLA spirit levels in a wide range of lengths to suit different tasks:
From 100 cm upwards, all models come with three vials, enabling even more precise horizontal and vertical measurements. This broad selection ensures every tradesperson can choose the right model for daily tasks – whether interior finishing, tiling or façade work. For confined spaces or large construction areas alike, the correct length is key to working efficiently and accurately.
As an experienced partner to the trade, Karl Dahm offers only tools that meet the highest quality standards. All SOLA spirit levels in our range are field-tested, meet stringent accuracy standards and deliver proven reliability in continuous use.
In addition, Karl Dahm provides expert advice and personal support – by phone, email or WhatsApp. Rely on years of experience, consistent quality control and a wide range of accessories and spare parts.
Choose tools that won’t let you down – for precise results, smooth workflows and satisfied clients.
The SOLA FOCUS vial provides up to 30% improved readability compared to conventional vials. Its optical magnification and high contrast allow the bubble to be clearly visible even in poor lighting conditions. This makes accurate alignment easier on construction sites, during installation work, and when working overhead. The FOCUS vial delivers greater speed, safety, and precision in everyday professional use.
SOLA spirit levels are designed for demanding construction conditions. The thermoresistant vials work reliably in very high and low temperatures. The UV-resistant liquid prevents fading and discoloration over time. This ensures long-term measurement accuracy, whether used indoors or outdoors under varying climate conditions.
Thanks to high-quality aluminum profiles, robust surface coatings, and precise vials, SOLA spirit levels are engineered for continuous professional use. They maintain their measurement accuracy for many years, even with frequent or intensive usage. With basic care, a SOLA spirit level is a reliable and cost-effective long-term investment.
Spirit levels 100 cm and longer include an additional vertical vial, enabling highly accurate vertical alignment. This is particularly useful when installing doors, setting tiles, aligning frames, or constructing walls. The third vial offers better orientation, greater precision, and faster workflow when working with vertical structures.
The ideal spirit level length depends on the application. Short models (around 40 cm) are perfect for tight or restricted spaces. From 100 cm upward, models come with three vials for greater versatility. Longer levels, such as 150 cm or 200 cm, are ideal for large-surface alignment, such as in drywall construction, masonry, or façade work.
The accuracy of ±0.5 mm/m means that the allowable deviation is just 0.5 mm over one meter in length. This high precision meets professional standards for tasks such as setting up components, alignment, and installation work. Every spirit level is quality-tested and documented to ensure consistent measurement reliability.
The ergonomic profile and strategically placed vials allow for easy and precise overhead reading. This is particularly advantageous when working on ceilings, shafts, or hard-to-reach areas. It saves time, prevents awkward movements, and increases efficiency in everyday professional work.
To maintain a SOLA spirit level, simply wipe it regularly with a dry or slightly damp cloth. Avoid aggressive cleaning agents, as they can damage surfaces. Store the tool dry and protected from impact to prevent deformation or scratches. With proper care, the spirit level will remain accurate and reliable for years.
SOLA uses permanently integrated factory-calibrated vials, meaning no readjustment is needed. This ensures consistent accuracy without any maintenance. In the event of damage, replacing the spirit level is recommended to maintain measurement quality.
The Karl Dahm online shop offers a wide selection of SOLA spirit levels, ranging from compact models to long precision levels. You benefit from expert support, fast delivery, and a comprehensive range suitable for construction sites, interior finishing, and installation work.
