Level 3N-3KL falls into the class of precise levels and is intended for geometrical leveling,
i.e. for finding the difference in height of ground points with the help of a sighting beam, which is automatically set horizontal. Light weight, small size, relatively high accuracy, an automatically set sighting beam, ease of operation make it one of the most effective modern geodetic instruments. The device is equipped with a light telescopic geodetic tripod of ShR-140 model and with rods of RN model.
