It provides 2" (0.6 mgon) angular accuracy through an absolute encoder, together with a 30x telescope, dual LCD displays and single-axis liquid-electric compensation over a ±3' range. The main unit weighs 4.1 kg and includes an internal Class 2 laser plummet.
Product Family: The DADI DE2A-L is the red-laser configuration within the DADI DE2A electronic theodolite series. It combines 2″ angular accuracy, an absolute encoder, a 30x telescope, dual LCD displays and a coaxial red upper laser with an effective working distance of up to 300 m under suitable visibility conditions.
The DADI DE2A-L is the red-laser electronic theodolite configuration within DADI's DE2A series. It is designed for construction, surveying and alignment applications that require horizontal and vertical angle measurement together with a visible red laser pointing function.
The DE2A-L provides 2″ (0.6 mgon) angular accuracy, an absolute encoder angle-reading system, a 30x erect-image telescope, a 47 mm objective, 1.5 m minimum focusing distance and single-axis liquid-electric tilt compensation with a ±3′ range. Its coaxial red upper laser has an effective working distance of up to 300 m (984 ft) under suitable visibility conditions.
The DE2A series is DADI's electronic theodolite product family and includes standard, red-laser, green-laser, long-range green-laser and autocollimation configurations. Within this family, the DE2A-L is the standard red-laser configuration, adding a coaxial red upper laser to the electronic angle-measurement platform.

Compared with the standard DE2A configuration, the DE2A-L adds a coaxial red upper laser aligned with the telescope line of sight. Its effective working distance is up to 300 m (984 ft) under suitable visibility conditions, providing a visible pointing function for construction alignment, layout and related surveying work.
Built-in coaxial red upper laser with an effective working distance up to 300 m under suitable visibility conditions.
The angle-measurement system is specified at 2″ (0.6 mgon) angular accuracy.
The DE2A-L uses an absolute encoder angle-reading system for horizontal and vertical angular measurement.
Erect-image telescope with 30x magnification, 47 mm objective diameter and 1°30′ field of view.
Liquid-electric tilt detection provides single-axis compensation over a ±3′ range.
The main instrument weighs 4.1 kg (9.0 lb).
The DE2A-L is designed for construction, surveying and alignment applications that require horizontal and vertical angle measurement together with visible red laser pointing. The coaxial upper laser can support alignment and layout tasks while the electronic angle-reading system provides conventional theodolite measurement.
The DE2A-L is suited to users who need a 2″ electronic theodolite and also require a visible coaxial red laser for pointing or alignment. Within the DE2A series, it provides the standard red-laser option, while MPE-02L provides the standard green-laser option and DE2A-GF500 is intended for longer-range green-laser applications.
