FIELD: measuring devices.
SUBSTANCE: invention can be used in control and measuring equipment, in particular in the technical means for astronomical observations. The counting and locking device for a sextant contains a body, shafts, grooves on the shafts, gears and a wheel for indicating the count. In this case, the gears mounted on the shafts are connected to the indication wheel and the minute wheel, the indication wheel is connected in the same plane with the minute wheel due to the shafts, between which a splined connection is installed, inside the case is divided into two segments by a partition, against which the spring mechanism rests, ending with a button, a rib is fixed between the spring mechanism and the shaft, and bearing units are installed in the partition between the shafts.
EFFECT: providing the ability to measure angles with an accuracy of one arc minute; simple transition to measurements in a different range of angle values; possibility of installation on a sextant.
