Auto tracking pulse total station GPT-8200Aseries

Auto tracking pilse total station GPT-8200Aseries
 
The GPT-8200A series is auto tracking total stations of a dual mode type. One station is capable of non-prism range finding and auto tracking, accomplishing all positioning from surveying to instrumentation.
The non-prism mode can comfortably measure distances beyond 1km.
Easy observation of off-limits areas such as hazardous areas stricken by disasters and airports.
High-speed auto tracking at 12°/s for instrumentation of moving objects. Powerful in instrumentation of various types in auto tracking and auto calibration.
