The Digital Hollow Inclusion (HID) Cell is a very low power, high-precision instrument purposely designed for in-situ monitoring of rock stress. The unit is designed to be permanently fixed within a borehole, and provides an immediate indication of strain and temperature.
The 3T borehole system designed for borehole diameters of 99 to 203 mm. The 3T analogue sensors can be combined with a DM24 borehole digitiser and EAM data acquisition module to build a fully networked authenticating digital instrument inside a single borehole.
The 5TB houses an accelerometer that is designed for strong-motion borehole studies in cased holes with diameters of 99 to 203 mm. The triaxial analogue sensor can be combined with the DM24 borehole digitiser or a surface digitiser to build a fully networked, integrated borehole monitoring system.
Sophisticated and adaptable, high fidelity seismic digitiser.The Güralp Affinity is a high-fidelity integrated digitiser and network communications unit that provides a convenient and expandable way of connecting analogue and digital instruments to your network.
Analog Extensometer is a sensor of electric current output type to measure displacement on the ground surface. The displacement is measured by change of the wire length between two (2) points that one is at a fixed site and another is at a moving area. Measurement mechanism is simple and the monitoring data is reliable.
Analog Water Level Meter measures water level and water temperature at a same time by one (1) probe. The probe is slim size with 18 mm in diameter only. User can use this for small size of monitoring well/hole.
GFA down-hole 3D geophone has three 10Hz geophones - oriented according to the x-y-z axis -housed inside a cylindrical probe for the determination of the time of arrival of the type 's' and type 'p' seismic waves.
The GEOLOGGER-GWS2 is an instrument for natural gamma and electrical logging used with a GW combination probe (MODEL-3493). It can simultaneously measure natural gamma, resistivity (16”, 64”) and spontaneous potential, which contributes largely to such works as groundwater surveys.
The Elast- Recorder is a borehole lateral load tester designed to figure out deformation characteristics of the ground ranging from soft rock to hard rock. The deformation characteristics become useful information especially for the construction of large scale structures such as dams, bridges and high-rise buildings.
The AUTO LLT 2 is a borehole lateral load tester that functions to determine the deformation characteristics of the ground from the relation between pressure inside its sonde and the inflated amount of its rubber tube.
The LLT-M is a borehole lateral load tester that functions to determine the deformation characteristics of the ground from the relation between pressure inside its sonde and the inflated amount of its rubber tube.
The McSEIS-PS is designed mainly for the measurement of downhole PS well logging in combination with a Borehole Pick (Model-3315). When used with our special programs, it is possible to carry out its data analysis easily on a commercial laptop PC.
