Detail Digital Thedolite Topcon DT-205
The Topcon DT-205 integrates the same high-quality advanced absolute circle reading technology found in Topcons high-performance total station products for more accurate field calculations. Topcon continues to deliver the highest quality optics and electronics you expect to find in Theodolites. The Topcon DT-205 weathers any wet or dust conditions in the field, allowing for a more productive day during inclement weather. Degree of protection against water is based on the standard IEC60529, whose definition is " water projected in powerful jets against the enclosure from any direction shall have no harmful effects" .
