TO THE NEXT GENERATION OF
The FM 301 blasting seismograph is designed and built for the 21st century.
GET IN TOUCHThe FM 301 utilise tri-axial accelerometers as an alternative to standard geophones.
This allows the unit to be lightweight and can be orientated in any direction.
Simply press the 'ON/OFF' button.
The unit then powers on and automatically goes into recording mode.
No external transducer block or air-overpressure microphone to connect.
Easy to setup.
All FM 301 units include a GPS receiver as standard.
This allows the user to know where monitoring was carried out*.
The GPS co-ordinates are written into the recorded file.
* GPS satellite signals are too weak to reach indoors and as such
they don't always perform well in indoor settings
Connect to the FM 301 unit with your mobile phone to check the latest results via our FM Seismograph App*.
* 4m Bluetooth range
TALK TO USEasy to use software allow users to download results from the FM 301 units.

In order to validate the innovative technology used in the FM 301 seismographs, a series of academic papers were submitted to International Society of Explosives Engineers (ISEE) and approved.
Both papers were presented earlier this year at ISEE Annual Conference on Explosives and Blasting Technique 2023.
