LT402L Dual-axis Laser Electronic Theodolite is a precision measurement instrument designed for engineering surveying applications. Integrating advanced optical systems with electronic sensing technology, it delivers reliable performance in construction projects, road surveying, and hydraulic engineering. The dual-laser alignment system enables simultaneous horizontal and vertical laser indication, working in tandem with high-precision angle sensors to ensure rapid baseline establishment and accurate positioning during measurement operations.
Equipped with an intelligent electronic angle measurement system, the device supports dual-axis synchronous measurement of horizontal and vertical angles, achieving 1" display resolution with full 0°-360° angular coverage. The visible red laser plummet maintains clear spot visibility within 15-100 meters range, facilitating quick identification of reference points at construction sites. Its vibration compensation mechanism effectively minimizes measurement errors caused by environmental disturbances, maintaining ±2" angle measurement accuracy across -10℃ to +50℃ temperature ranges.
User-oriented features include a dust-proof 6-button control panel and high-contrast LCD display, complemented by an erect-image telescope system that ensures legible data reading in complex working conditions. The built-in rechargeable lithium battery provides up to 30 hours of continuous operation, supported by Type-C universal charging interface for convenient power replenishment. Constructed with die-cast aluminum framework and multi-layer dust/water resistance treatment, the instrument maintains operational stability even in challenging field environments.
