English Introduction
The SANDING DT-02L Laser Electronic Theodolite is a high-performance surveying instrument designed for various engineering measurement applications. It features advanced technology that ensures high precision and efficiency.
In terms of performance, the DT-02L uses an absolute encoding angle measurement method with an angular measurement accuracy of 2 seconds and an electronic bubble compensation accuracy of 1 second, with a compensation range of ±4′. The horizontal and vertical disks use a double-read method to ensure measurement accuracy. The instrument is equipped with a laser centering function, which can quickly and accurately complete the centering operation.
The telescope part of the instrument has a magnification of 30 times and an effective aperture of 45mm, with a field of view of 1°30′ and a minimum viewing distance of 1.4m. The laser centering device has a wavelength of 635nm, a power of 0.5mW, and an effective range of up to 120m. In addition, the instrument also has a laser pointing function, which can provide more intuitive assistance for measurement.
Regarding display and operation, the DT-02L is equipped with a dual-panel LCD display in Chinese, with a simple and clear interface that is easy for users to quickly master. The instrument can operate in an environmental temperature range of -20℃ to +45℃, making it suitable for various harsh conditions. The onboard battery is a rechargeable nickel-hydrogen battery or AA battery, with a continuous working time of up to 10 hours.
The SANDING DT-02L Laser Electronic Theodolite is widely used in third and fourth-order triangular control surveys for national and urban areas, as well as in engineering surveys for railways, highways, bridges, water conservancy, mines, and other fields. It is also suitable for building construction, large equipment installation, cadastral surveys, and topographic surveys.
