ARP 200 system

The system is used for registration and analysis of low-frequency vibrations of the ground and structures in areas at risk of mining, tectonic, and communication tremors. The modular structure of the system allows the implementation of distributed measurement networks, wireless data transmission is implemented via GSM mobile telephony.
