The Gecko is our 7th generation of earthquake recorder with an integrated user interface for simple field operation.
Modern seismology requires continuous recording of the earth’s movements, and the Gecko is always on and continuously storing data to its removable SD card. The Gecko uses the latest 32-bit Analogue to Digital Converter (ADC) chips to maximise the range of amplitudes that can be recorded – the ratio of the largest to the smallest recordable signal is a factor of almost 8 million to 1.The Gecko has 4 channels, perfect for a triaxial geophone plus microphone for vibration and blast compliance monitoring. Continuous data is captured continuously at 50 to 4000 samples per second, covering a broad band of frequencies from the longest period seismometers to geophones, microphones, and accelerometers with up to 1.6kHz flat frequency response.
Data can also be telemetered to a remote computer via cellular modem or Ethernet/WiFi adaptor. The Gecko recorder uses under 1W of power (with passive sensors) so you can record for over a month using a car battery, or indefinitely with a small solar panel and small battery backup.
