9015.20.40.00 - Electrical

HTS 9015.20.40.00 specifically covers electrical theodolites and tachymeters. These instruments are sophisticated surveying tools that utilize electronic components to measure angles and distances with high precision. They are distinguished from purely mechanical versions by their reliance on electrical power and integrated circuits for their operational functions, such as digital displays of measurements, data logging capabilities, and sometimes internal compensation for environmental factors.

This category differs from its sibling, HTS 9015.20.80.00 ("Other"), which would encompass theodolites and tachymeters that are not primarily electrical in nature, such as older, purely optical or mechanical models. The key differentiator lies in the presence and primary function of electrical components for measurement and data processing within the instrument.

As a leaf node, HTS 9015.20.40.00 does not have further subdivisions. Therefore, classification within this code is determined by the instrument's primary function as an electrical theodolite or tachymeter, used for surveying, engineering, and construction projects requiring precise angular and distance measurements. Examples include modern total stations that combine the functions of a theodolite and an electronic distance meter.
