Theodolite Topcon DT-209L

Topcon' s DT-200 Series represents the highest accuracy and value in Digital Theodolite technology. Only Topcon, with 75+ years of experience manufacturing the World' s most precise Optical Survey instruments can offer the precision, durability, and advanced technology found in each DT-200. Durability, accuracy, and value, that' s Topcon and that' s the DT-200 and DT-200L Series of digital theodolites. Water and dustproof Get the work done, even in less than perfect condotions. All DT-200/ DT-200L Series instruments are rated to IP66, standing up to even the rainiest conditions. And each telescope is gas charged to further avoid moisture intrusion and limit or eliminate lens fogging. Laser accurate ( DT-200L Series only) Topcon' s World Leading laser tecnology is incorporated in to the DT-200L Series to aid in fast, confident alignment. The 633nm bean us emitted directly from the aperture, but does not impede viewing, in fact it' s not even visible when sighting through the lens. ( Class II laser beam) Simple Operation Each DT-200 provides large, high contrast, back-lit LCD' s on both sides of the instrument. And the five button interface panel is si simple to use your crew won' t require any special trining to put your DT-200 to use day-in and day-out. ( DT-209/ 209L: single side display) The ultimate in continuous operation The DT-200/ DT-200L Series provides up to 140+ hours of operation in Angle Measurement mode on 4AA batteries, better than any other model! And when it is time to charge batteries, it' s as easy as snapping out the old ones and snapping in the new. Even when using the laser, power consumption is extremely low providing 80 hours of continuous operation.
