Topcon Provides Japan Quality Products
Topcon performs tough environmental tests to ensure long-term operation even under rough site environment. GM Series total stations are thoroughly inspected with dust-proof and water-proof test chambers. In addition, various tests against vibration, drop, temperature, and humidity were successfully passed to achieve the best environmental spec. Also, the measuring distance accuracy test on base line and the instrument leveling and angle accuracy test and adjustment by collimator system ensure your satisfaction on the GM Series product quality.
