Seismic Premonition Sensors
¡¡¡¡Seismic premonition sensors are mainly made up of Ground Temperature Sensor,
Water level Sensor, Air Temperature Sensor, Air Pressure Sensor, Precipitation Rain Fall Sensor,
Ground Electric Field Sensor, Electromagnetic Wave Sensor and Gas Radon Sensor etc.. All sensors
have high integration, intelligentize and automatization£¬they are easily installed, used and supported.
