Bubble Inclinometer for Field Tilt Measurement
bubble inclinometer
A bubble inclinometer gives you a direct reading of tilt, right at the measurement point. No cables, no electronics, no calibration drift—just a precise glass vial and etched scale. Geotechnical engineers have relied on these for decades, whether checking formwork alignment, monitoring a slow-moving slope, or verifying the verticality of piles. Kingmach supplies these instruments as part of a wider range of manual monitoring tools. They’re simple, but when you’re standing in a trench in bad weather, simplicity is exactly what you need. We’ve heard from site supervisors who keep one in the truck at all times, just to be sure.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach’s bubble inclinometers come from years of manufacturing experience in geotechnical instrumentation. The core is a high-sensitivity spirit level fixed to a sturdy housing, typically anodized aluminum or stainless steel. Graduations are laser-etched, so they don’t wear off with repeated use. A few models include a magnetic base for hands-free attachment to steel structures. You can also get versions with a longer vial for finer resolution. Because Kingmach handles everything in-house, customization is straightforward: we’ve done special ranges for dam monitoring, corrosion-resistant finishes for marine environments, and dual-axis setups for simultaneous X-Y readings. All units ship with a calibration certificate traceable to national standards. If your project calls for a specific scale or mounting style, the engineering team can adjust the design without a massive minimum order. This flexibility sets Kingmach apart from catalog-only suppliers. You’re not buying off the shelf; you’re getting an instrument built to fit your actual measurement task.

FAQ
Common technical questions
What is the typical resolution of a bubble inclinometer?
Standard models read to 0.5 degrees. High-resolution versions with an extended bubble length can resolve 0.1 degrees under good lighting. The actual precision also depends on how carefully you read the meniscus.
Can a bubble inclinometer be used for long-term monitoring?
It’s designed for spot checks rather than continuous monitoring. However, you can pair it with a fixed mounting plate and record readings manually over time. For automated data, an electronic in-place inclinometer would be more practical.
Is the sensor replaceable if the vial gets damaged?
Yes, the vial assembly is usually a separate module. We keep spares for most models, and field replacement takes just a few minutes with basic tools.
Does Kingmach offer protection against moisture and dust?
Standard housings are sealed with O-rings and rated IP65. For submersion or highly corrosive settings, we can build the unit with double seals and 316 stainless hardware.
How do I choose between a uniaxial and biaxial bubble inclinometer?
If you only need to measure tilt in one direction—like forward/backward on a wall—a uniaxial unit is lighter and cheaper. Biaxial models give you two orthogonal readings at once, which is useful for borehole alignment or complex structure monitoring.
