Sensors and instruments for monitoring, measuring and displaying movements in rocks and walls.
Jointmeter JM
Jointmeters are mechanical measuring instruments for the surveillance of movements of joints and cracks in rock, concrete, masonry and at steel constructions.
Setdeflectometer ERDM-RDM
Mechanical gauges with digital or analog reading for measuring of mechanical extensometers and jointmeters.
Telejointmeter TJM
The Telejointmeter TJM is a measuring system with electrical transducers for the surveillance of movements of joints and cracks in rock, concrete, masonry and at steel constructions.
Rockmeter RM-RMT
Single or multiple-rod rockmeters are used for measuring displacements and deformations in abutments of dams and bridges, in terrain and rock slopes, tunnels and in excavations etc.
Teletensometer TTP
Teletensometers TTP are used to measure movements of joints, cracks and rocks as well as of rod extensometers or to measure linear displacements in earth dams, at slopes and rocks or at pressure pipes and so on.
Deformeter EDU
The Deformeter EDU is a precision strain meter with 250 or 500 mm measuring base for mechanical engineering, underground and building constructions as well as geophysical applications.
Tensotast TAS
The Tensotast TAS is a precision strain meter with 20 up to 200 mm measuring base for mechanical engineering, underground and building constructions as well as geophysical applications.
Water level gauge KLL
The electric water level gauge is used for rapid and reliable measurement of water levels in wells, observation tubes and narrow boreholes.
Measuring device for length changes-ZGL
The measuring device for length changes ZGL is a purely mechanical measuring system based on an Invar wire which is stretched between a fix mounting point and a tensioning device with support for a diel gauge.
