Welcome to RTKSurvey.com
The THINRAD TAL1 is a high-precision optical automatic level designed for demanding leveling and elevation measurement. Its 55× telescope provides high magnification for detailed staff observation, making it particularly suitable for longer sight distances and precision leveling work.
As the highest-grade model in the THINRAD TAL optical level range, TAL1 is designed for users who require greater optical magnification and higher leveling performance than standard engineering levels.
Key Features
55× high-magnification telescope
Z1-level precision positioning within the THINRAD optical level range
1.0mm standard deviation for 1km double-run leveling with an invar staff
45mm objective aperture
Automatic compensator with ±15′ working range
0.6m minimum focusing distance
Suitable for precision and long-distance leveling
Designed for road, railway, pipeline and engineering surveying
High-Magnification Leveling for Precision Work
The main advantage of the TAL1 is its 55× optical magnification. For leveling work involving longer sight distances, detailed staff readings and strict elevation control, the higher magnification can provide a more useful viewing experience than conventional 32× instruments.
This makes TAL1 a suitable option for precision construction surveying, railway and highway projects, pipeline work, deformation-related leveling and other applications where elevation accuracy is important.
