The frame decides whether the vial still tells the truth in a year · review
The level built around keeping its vials where they were set: Stabila states ± 0.5 mm (0.02 in)/m in the normal position, permanently bonded vials, and accurate reading from −20 °C (-4 °F) to +50 °C (122 °F).
What the figures leave us with The one built to still be accurate in three years. Fewer features than the Bosch, more attention to the part that fails.
Stabila’s Type 70 is specified around a single failure mode: a level that was accurate and stopped being so.
A measuring accuracy of ± 0.5 mm (0.02 in)/m in the normal position. LOCKED VIALS construction, in which vial and profile are aligned once and then permanently bonded, stated to give long-term precision. Quality vials with fluorescent liquid, in high-transparency acrylic with precision-ground inner contours set flush with the body. Exact reading from −20 °C (-4 °F) to +50 °C (122 °F). A light aluminum profile with a coated measuring face and smooth sides. Plastic end caps to protect the profile against impacts.
Almost every level is accurate when new. What separates them is what happens after eighteen months in a van. The usual failure is not the aluminum bending — it is the vial capsule shifting a fraction in its housing, which no one notices because the bubble still sits between the lines on a surface that is roughly right. Bonding the capsule to the profile is the direct answer to that.
Read a surface. Rotate the level end for end in place, without moving it along. Read again. The bubble should sit identically. If it does not, the error is in the level, and half the apparent difference is the size of that error. This works on every level in this hub, and it is the check the published figures cannot do for you.

A level has a normal position and an over-head position, and the figures differ. Stabila states ± 0.5 mm (0.02 in)/m for the normal position. Most makers quote one number without saying which position it applies to; Stabila names it.
Vial liquid changes viscosity and volume with temperature, and the bubble stops behaving. Stabila states exact reading from −20 °C (-4 °F) to +50 °C (122 °F), which is a real specification for anyone working outside in winter and the only such figure in this hub.
Stabila states the vials and the profile are aligned exactly once and then permanently bonded together, which is their answer to the way levels normally go out of true — the vial mount shifting in its seat.

A level that stays right. The bonding of the vials is the specification you are buying.
Amazon reports what buyers took in the month before this page was last checked: at least 50.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

20 cm (7.9 in) · 1 mm (0.04 in)/m stated · two vials · rubber end bumpers
A 20 cm (7.9 in) pocket level with ground bearing faces, a stated accuracy of 1 mm (0.04 in) per meter and rubber bumpers at both ends. The loosest published figure here, in the smallest and cheapest body.
Best for: The level that lives in a drawer or a kitchen cupboard for hanging pictures and checking appliances.
Three levels · ± 0.5 mm (0.02 in) stated · ± 0.75 mm (0.03 in) turn-over · three vials each
Three levels at 40, 60 and 100 cm (39.4 in), and the only entry in this hub that publishes a turn-over figure — ± 0.75 mm (0.03 in) — which is the number that describes whether a level is telling the truth.
Best for: Equipping a workshop from nothing, where owning the right length matters more than owning the best one.
60 cm (23.6 in) · 0.5 mm (0.02 in)/m stated · V-groove · two marking sliders
A 60 cm (23.6 in) aluminum level stating 0.5 mm (0.02 in)/m, with fluorescent vials, a double metric scale that turns it into a rule, a V-groove for pipes, and two sliders for marking leveled points.
Best for: The general-purpose level for someone who would otherwise carry a level and a rule.
