For precise measurements and results that are impressive: Our measuring tools are indispensable helpers for every craftsman. In the sub-category you will find:
The 28 cm tile template is the ideal tool for precise and fast measuring and transferring shapes such as door frames, columns or overhangs directly onto tiles. You save valuable time on the construction site without complicated measuring - simply apply the template, transfer the pattern and cut the tile to size.
With a length of 28 cm and a measuring depth of 45 mm, the measuring template is ideal for everyday use. The folding rule can stay in the toolbox, as this practical aid enables error-free work in a matter of seconds. An indispensable aid for every tiler!
The assessor equipment set, art. no. 11548, is an indispensable tool set not only for assessors, but also for tilers. It enables precise testing, documentation and rectification of damage or complaints - ideal for use on the construction site. With this high-quality set, you can quickly and clearly master crack widths, flatness deviations and other measuring tasks. You can find more details here.
Contents and functions of the set:
Modern laser technology for maximum precision: Our laser measuring devices facilitate exact alignment and measurement on construction sites. From floor lasers to cross line lasers - you will find the right solution for your requirements here.
The Spider floor laser from Karl Dahm in the colour green impresses with its clearly visible green laser line and innovative functions that make precise work easier. Thanks to the height-adjustable legs, the working area can be individually adapted, while the integrated circular bubble enables exact levelling even on uneven surfaces. The rotating laser head ensures precise fine adjustment. You can find more details here.
The Plano 4D Green line laser, item no. 41400, offers maximum precision, user-friendliness and innovative laser technology - ideal for construction and interior design projects. With its powerful Real Green technology, the laser produces high-contrast, clearly visible lines that deliver optimum results even in difficult lighting conditions.
Highlights include two vertical and two horizontal 360° laser lines, which enable comprehensive levelling, alignment and plumbing work, as well as a horizontal line close to the ground for precise floor work. The self-levelling laser automatically compensates for unevenness (±3°) and achieves an accuracy of ±0.3 mm/m. Thanks to the tilt function, it is also suitable for working at an angle, for example on stair railings. The pulse mode ensures clear lines at long distances (up to 80 m with receiver). You can find more details here.
The proven calcium carbide method (CM measurement) enables the residual moisture in screed and other materials to be determined quickly and accurately. This measurement is essential to ensure that the substrate is dry enough for tiling and that no damage is caused by moisture.
The CM measurement is based on a chemical reaction between calcium carbide and water, which produces acetylene gas. The resulting pressure is read on the mechanical pressure gauge, which allows the residual moisture of the screed to be calculated precisely.
The CM moisture analyser Classic is an indispensable tool for tilers and builders to avoid expensive complaints. It takes just a few minutes to use and provides accurate results without the need for complicated conversions. The device is easy to use and contains everything needed for the measurement, including a digital scale, calcium carbide ampoules and a robust tool case. The CM Moisture Meter Classic offers a quick and reliable solution for measuring screed moisture. You can find more details here.
The GM-200 moisture meter precisely measures the moisture content in floors and walls, ensuring ideal conditions when laying tiles. Thanks to the 9 measuring scales, a wide variety of materials such as anhydrite screed, cement screed, concrete, gypsum plaster and hard and soft wood can be reliably tested.
The ergonomic design with non-slip rubber ensures safe handling, while the high-resolution display offers optimum readability. Without recalibration after each measurement, the GM-200 is always ready for immediate use. You can find more details here.
Karl Dahm - Your partner for professional tiling and construction tools
Benefit from our decades of experience and our extensive range of spirit levels, laser and measuring tools. Discover high-quality products that make your work easier and ensure perfect results!
A professional spirit level needs to be robust, highly accurate, and reliable on demanding construction sites. KARL DAHM Goldpunkt spirit levels feature precision-ground aluminum profiles and adjustable vials for long service life. SOLA Profi spirit levels are known for their FOCUS vials, which offer exceptional clarity and easy readability. STABILA Aluminium spirit levels provide high measuring accuracy and are extremely durable. All three brands are designed specifically for daily use in tiling and construction and ensure consistent, reliable results for years.
Personalizing your spirit level with laser engraving offers practical and visual advantages. A unique engraving ensures your tool is unmistakably yours – ideal for preventing loss or confusion on busy job sites. It also enhances your professional image with customers. At Karl Dahm, you can have KARL DAHM, SOLA, and STABILA spirit levels permanently and abrasion-resistant engraved with text or logos. This makes personalization perfect for professional teams, gifts, or unified branding.
For flawless tiling results, you need more than just a spirit level. Measuring wedges and angles help with precise alignment. Contour gauges (like the 28 cm model) allow quick and accurate shape transfers onto tiles. Measuring gauges and circle dividers enable precise cutting for curves and special layouts. For inspections and documentation, the Inspector/Expert Set is ideal, featuring measurement wedges, crack width templates, marking arrows, and a digital caliper. These tools ensure accurate, efficient, and professional work.
Modern laser measuring tools, such as the Spider Floor Laser or the Plano 4D Green Line Laser, project highly visible reference lines on floors, walls, and ceilings. This speeds up work, reduces measurement errors, and improves precision—especially with large areas, tile patterns, wall lines, and installation points. Green laser technology ensures significantly better visibility than red lines, even in bright work environments.
The CM (Calcium Carbide) method determines the exact moisture content in screed. Excess moisture can lead to hollow spots, cracks, adhesive failure, or mold under tile flooring. The CM Moisture Meter Classic and the GM-200 Moisture Meter provide fast, reliable measurements and clear results without complicated conversions. These tools are essential for tilers and construction professionals to avoid costly complaints and damage.
Green lasers operate at a wavelength that the human eye perceives more strongly than red light. Devices like the Plano 4D Green use Real Green Technology, producing crisp, bright lines that remain visible even in sunlit or large rooms. This improves working speed, accuracy, and efficiency—especially on professional construction sites.
