Gecko: Earthquake Recorders & Digital Sensors

The Gecko is our 7th generation of earthquake recorder with an integrated user interface for simple field operation.

The Gecko comes in two casings: a Compact water-resistant exclosure with an iPhone-sized footprint; and a Rugged version that houses the electronics in a waterproof chassis with a CD-sized footprint, bringing beautiful style to the Gecko’s efficient substance.

Several Gecko models are available with internal triaxial sensors housed inside a waterproof body – acceleration sensors (SMA and SMA-HR) and velocity sensors (Blast, ForceTremor, and Prism) – providing a solution for almost every application. The sensors used in these models are also available in external casings with cables to connect to the Gecko Compact or Rugged.

Description

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.
