Slimhole Seismometer Extreme Condition: Model F41-15.0
High-tilt and high temperature seismometer for geothermal environments, test holes and behind casing installation.
The F41-15.0 is a high-tilt and high-temperature triaxial borehole seismometer designed for installation in high temperature environments up to 150 °C such as geothermal systems. Its primary use is in for micro-earthquake detection and analysis. The F41-15.0 is suitable for test well or behind casing installation. Optional design features include extra elements wired in series to boost available output as well as sinker weights to aid deployment. An alternate slimhole model, the F50-4.5 offers a lower corner frequency in exchange for a lower tilt tolerance.
Features:
-
Fixed geophones, omnidirectional functionality
-
Withstands up to 150 °C (with higher spec. models in development)
-
Passive sensors
-
For permanent or semi-permanent installations
-
Custom versions can include accelerometers, magnetometers etc.

Slimhole Seismometer: Model F50-4.5
Slimhole seismometer for high-pressure environments, test holes and behind casing installation.
The F50-4.5 is a triaxial borehole seismometer that combines robust construction and a slim profile. Its primary use is for micro-earthquake detection and analysis in environments up to 70 °C, such as geothermal systems. The F50-4.5 is suitable for test well or behind casing installation. Typical design features include three elements wired in series to boost available output as well as sinker weights. An alternate model, the F41-15 offers a higher tilt tolerance in exchange for a higher corner frequency.
