THINRAD TL-03 Digital Level

The THINRAD TL-03 is a high-precision digital level designed for professional leveling, engineering surveying and elevation control. It automatically reads barcode staffs to measure height and distance, while built-in programs support leveling, setting out, route surveys and other field operations. With 0.3 mm/km accuracy when used with an Invar staff, the TL-03 is suitable for both precision leveling and general engineering work.

Professional Digital Leveling with THINRAD TL-03

The TL-03 is designed around a complete digital leveling workflow rather than simple electronic staff reading. Its onboard software supports different leveling procedures, including first- through fourth-order leveling, while internal data management allows field observations to be stored and transferred for further processing.

The instrument can also connect through Bluetooth or RS-232 for digital field workflows. With automatic height and distance measurement, the TL-03 can help reduce manual reading and recording work on projects where consistent elevation data is important.
