Theodolite Topcon DT 205L / 207L / 209L

Digital Theodolite DT-200 series

	Longer battery powering duration Longer battery powering durations using alkaline batteries. Continuous angle measurement for 150 hours (DT-213). 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 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 a sudden torrential rain and dirt. The theodolite can be used reliably at work sites under severe conditions. JIS C 0920 protection class IP66 (Dustproof and waterproof types)
