We design, fabricate and install 15 Hz and 4.5 Hz seismometers. They are made to order in any desired combination. Continuous temperature sensors can also be incorporated into the borehole tool string with the seismomters.
We also test seismometers with our Bird Dog 3 equipment and can do so for you on request.
Our tools can be deployed to depths over 5000 metres and withstand continuous operating temperatures of 200 °C.
