Invar Barcode Staff for Digital Level

This invar steel barcode staff is specially designed for digital levels. It is made of high-quality imported invar steel with extremely low thermal expansion coefficient. Its length remains stable without being affected by day and night temperature difference and seasonal climate, effectively eliminating measurement errors caused by temperature.High-precision digitally controlled engraved black and white identification barcodes are neatly arranged on the staff surface, which are highly compatible with all mainstream digital levels. It supports fast automatic scanning and accurate data reading, greatly improving leveling survey efficiency.With special surface protection treatment, it is waterproof, moisture-proof, rust-proof and corrosion-resistant, suitable for harsh construction site environments such as humidity, wind sand and strong sunlight, ensuring long service life.The staff is flat and straight with strong rigidity, not easy to bend or deform, maintaining stable precision for long-term use.It is widely used in precision leveling measurement, settlement observation, road and bridge surveying, building elevation monitoring, geological exploration and other high-precision engineering fields, an essential high-precision accessory for professional surveying projects.
