The Topcon DT-200 series integrates the same high-quality advanced absolute circle reading technology found in Topcon’s high-performance total station products for more accurate field calculations; and they continue to deliver the highest quality optics and electronics you expect to find in Topcon theodolites.
Topcon DT-200 Series Features:
- Long Battery Life
- Waterproof and Dustproof Digital Theodolites
Available in three affordable models delivering 5″, 7″, or 9″ angle accuracy, there is a DT-200 theodolite perfect for any job. Like the DT-100 series, the DT-200 series weathers any wet or dust conditions in the field, allowing for a more productive day during inclement weather. All models are also compact and lightweight for easy portability; and their simple operation provides precise measurement in a functional, hassle-free package.
- Longer battery powering duration
Longer battery powering durations using alkaline batteries. Continuous angle measurement for 150 hours. Laser continuous angle measurement for 45 hours. - Absolute encoder is used
Detection of 0° position is no longer needed. Stable, high-accuracy measurement. - Laser pointer
The laser pointer is injected in a collimation direction by simply operating one switch. Workers can perform work without guidance by observation personnel. - Excellent waterproof structure
The theodolite body is guarded against sudden torrential rain and dirt. The theodolite can be used reliably at work sites under severe conditions.
