We provide several types of level instruments. First, and most common, is a spirit level. Small glass vessels filled with liquid (commonly alcohol) are placed on a ruler and are used to indicate the inclination angle of a certain surface. The first spirit level was introduced in 1661, and since then this tool has gained popularity over the world. Another type of level device we offer is a plummet (also called plumb bob). It's considered to be a plumbers device, however it's fields of application stretch far beyond plumbing. The first application of this instrument date back as far as ancient Egypt. It is a vertical analog of a liquid level. We also supply electronic leveling devices. These utilities have electronic sensors and microprocessors to calculate precise inclinations. Such gadgets are utilized in high-precision tasks and in laboratory set-ups.
