Hệ thống đo lún đa điểm đầu đo A-6 (Multiple Point, Rod, Flexible) Geokon 1280 (A-6)
The Model A-6 Flexible Rod Extensometer uses continuous lengths of fiberglass rods (inside protective tubing), cut to customer-specified lengths, coiled at the factory and shipped ready for installation. The extensometer is lightweight, making it easier to handle for installation and less costly to ship. On-site assembly time is minimal and the installation procedure is simplified.
¹Note that the size of the hole required increases with the addition of more measuring points.
