Spirit levels go back a long way. The Romans used water-filled vessels when building aqueducts. The modern spirit level was invented by Frenchman Thévenot as far back as 1661. His original contained water rather than spirit, and ours are filled with an easy-flowing oil-based liquid.

We offer a range of spirit levels for all possible work situations. There are spirit levels in aluminium and plastic, specially-adapted and multi-functional. We also produce several that can be equipped with accessories to help you carry out other measurement tasks in your work.

Low manufacturing tolerance.

Manufacturing tolerance is the sum of all faults that may occur during production: the vial's radius and assembly into the profile; the parallelism and straightness of the profile.

All spirit levels are checked before leaving the factory. To guarantee accuracy of our spirit levels, we manage our manufacturing process using a quality system that is certified in accordance with ISO 9001.

Durable profile.

Levelling forcesAluminium gives the profile additional durability without the spirit level becoming too heavy. Profile strength is primarily affected by two factors – the size of the hole for the vial and the thickness of the profile. The larger the hole the less the durability, and the thicker the walls the greater the durability.

The profiles strength is checked by being subjected to forces from above (bending) and forces from the short sides (tension).

The length of the spirit level also plays a part – the longer the level, the greater the level of accuracy. However, you must take extra care when using a long spirit level to ensure that the profile does not become warped or distorted. In order to achieve the best possible durability, our spirit levels are exposed to extreme forces in a series of stringent tests.

Levelling MST vs HV40

Easy to read levels.

In order to make our vials easy to read, we have equipped them with a magnifying lens that makes the movement of the bubble much clearer. In addition, the vial is also produced with a luminescent reflector that means that it is easily readable even when light conditions are not at their best.

Levelling easy to readThe vial also has a series of rings inside the shell that makes it easy for you to read and minimizes errors. The rings extend around the entire vial, meaning that the level can be easily read even from below.

The liquid in the vial is a coloured low viscosity oil mixture that gives the bubble optimal freedom of movement and makes it easy to read. The liquid is highly resistant to ultraviolet light and fluctuations in temperature.

It is also anti-static, i.e. it is not affected by static electricity. This means that our spirit levels are easy to read in the majority of environments and under the most difficult of conditions.

Right sensitivity.

Levelling sensitivityThe sensitivity of the vial determines how quickly the bubble moves when one end of the spirit level is lifted. If the vial is too sensitive, the level may be difficult to work with. However, the more sensitive the vial, the more accurate your work will be.

The radius of the vial determines its accuracy; a larger radius means that the bubble can move more easily. Sensitivity is measured in mm per meter.

The parameter is based on a spirit level 1 meter long, and how high one end of the level must be lifted for the bubble to move 2 mm. Certain applications require a higher sensitivity, which is why we produce spirit levels with varying degrees of vial sensitivity.

Sensitivity of Hultafors spirit levels
Radius (mm) Sensitivity (mm/m) Model
150 13,3 TVP
200 10 HV
1000 2 Libella 2000
2000 1 MST

Sensitivity is determined by the radius of the vial. The radius is adapted according to the level's area of use.
