"The Accuracy of Your Work Depends on the Quality of Your Level."
Founded in Annweiler am Trifels, Germany in 1889 by Gustav Ullrich, STABILA revolutionized measuring by inventing the patented spring-joint folding ruler and the modern acrylic glass vial system permanently cast into the spirit level body.

Precision Without Compromise
On a modern construction site, precision is not a luxury — it is a legal and structural requirement. STABILA spirit levels are manufactured using a proprietary casting process where the acrylic glass vials are set into the high-strength aluminum profile using an epoxy resin that cures without shrinking or shifting.
Unlike ordinary levels whose vials are fastened with mechanical screws or clips that vibrate loose when dropped or exposed to Canadian temperature swings, a STABILA level remains permanently calibrated for life.
Locked Vial Technology
Vials cast permanently into frame — no readjusting, zero loss of calibration over years of heavy use.
Certified Reverse Accuracy
Guaranteed measurement precision in both normal and upside-down reverse positions (0.5 mm/m).
Engineered for Extreme Climates
Anti-static fluorescent vial liquid operates reliably from -20°C to +50°C without freezing or bubbling.
