Renovated TT5 Th 40 Theodolite + Wooden Box USSR, Plant №217

Description

Theodolite teheometr-TT-5 - geodesic goniometer, via which the operation is carried tacheometric, measuring horizontal angles and inclination angles, determining magnetic azimuth direction and distance measurement on cotton rangefinder.
One of the most common in the USSR theodolites, is an improved model theodolite CT-50.
Theodolite closed design, all his vital parts and components are protected from direct exposure to dust and moisture.
The applied theodolite telescope with internal focusing and a conical vertical axis.
The first limb models was a circle with a soldered brass ring neyzilbertovym on which are plotted division in later models limb and alidade was made of an aluminum alloy with a special electrochemical finishing.
