【English Introduction】
Changzhou Dadi Electronic Theodolite DE2AL Dual-Laser Plummet Theodolite
The DE2AL electronic theodolite from Changzhou Dadi integrates optical measurement with laser positioning technology, delivering high-precision surveying solutions for construction engineering, roadworks, geological exploration and other measurement-intensive applications. Featuring dual-axis laser plummet system, this instrument enables rapid point alignment in complex environments, significantly improving operational efficiency.
Equipped with a high-sensitivity electronic angle measurement system, the DE2AL achieves advanced angular measurement accuracy with 1" minimum display resolution for both horizontal and vertical axes, meeting stringent requirements for precision engineering surveys. Its dual-axis automatic compensation function continuously corrects measurement deviations caused by ground unevenness or vibrations, ensuring data reliability. The visible red laser plummets provide clear targeting from 0.5m to 30m, particularly suitable for foundation pit monitoring and steel structure installation that require vertical alignment.
The lightweight magnesium alloy body (4.3kg) combines with ergonomic controls to reduce operator fatigue during prolonged use. With an extended operating temperature range (-20℃ to +50℃) and IP55 protection rating, the instrument maintains stable performance in challenging environments. The rechargeable lithium battery supports 30 hours of continuous operation, accommodating full-day fieldwork demands. Intelligent data processing functions include automatic angle calculation and measurement error compensation, while optional data export interfaces enhance workflow integration with modern digital systems.
