We own five bi-axial tiltmeters, model 701-2A(4X) from Applied Geomechanics. They are contained in a weatherproof housing and have adjustable legs, making them ideal for temporary installations. Tiltmeters measure changes in the tilt of a structure and work comparable to a spirit level. Our units have an accurracyof 1 microradian which is about 0.000057 degrees. This corresponds to lifting a 1 km long structure on one end by one mm. Below a summary of the technical specifications of the 701-2A(4X).
