Levels with tribrach
prices on 15 models— a device for mounting on a tripod or other support used in surveying instruments — including many optical levels, as well as some rotary instruments.
The tribrach has the appearance of a characteristic base with three legs, which are complemented by screws; screws allow you to change the height of each individual leg relative to the base, providing a very accurate exposure of the device on the horizon. In addition, such a stand may have other additional functions — for example, a plummet (an optical or laser system for precise installation over a strictly defined point).
