Laser levels and construction tools, in general, are used for a variety of purposes in construction and surveying. Laser levels specifically are used to, you guessed it, make sure things are level, or off-level at a specific angle or grade. This could mean something as simple as hanging a picture in your home, or more complex and impactful like paving a road to a specific grade or making sure the floor of a building is flat. There are several types of laser levels including rotary lasers and line lasers, among others.
想一想在雨中驾驶汽车，您是希望道路上有积水，让您水陆两用，还是希望道路有一定的角度，让水向一侧或另一侧流去，使您更安全地行驶到目的地？激光水平仪的精度通常以±毫米/米或毫米/米为单位定义，即每米距离的潜在垂直误差为毫米，或。
有兴趣了解%坡度与度数的角度吗？当你知道%的坡度（或坡度），坡度的角度（见α），或上升（见Δh）和运行（见d）时，你可以进行各种转换。

Note that laser levels typically use very high accuracy tilt sensors in order to maintain precise measurements over long distances. Typical Fredericks sensors for these applications are the 0703-1602-99 for ±25° measurement with ±0.005° repeatability and the 0703-0711-99 for ±3° measurement with ±0.001° repeatability. Both of these are single-axis solutions, but two sensors can be mounted perpendicular for dual (2) axis measurement. As an example, let’s convert these repeatability specifications into mm/m measurements using the equations we talked about before:
This can also be compared with our wide range of tilt sensor solutions, which are a less accurate option but provide 2-axis measurement in a lower-cost package. For example, the 0717-4313-99 tilt sensor has a measurement range of ±60° with ±0.05° repeatability, which converts to the following accuracy in mm/m:
Note that these repeatabilities (also called accuracy) specifications typically can’t be achieved with low-cost MEMS solutions, or any other low-cost tilt measurement solutions, making electrolytic tilt sensors ideal for this application. Additionally, electrolytic tilt sensors have no moving parts so they don’t have any measurement properties that change over time or temperature. This means that they’re much more repeatable over time and temperature than other solutions. To learn more about electrolytic tilt sensors, check out this video:
