Gecko: Earthquake Recorders & Digital Sensors

The Gecko is a 7th generation of earthquake recorder with integrated user interface for simple operation. With 4 channels of data captured at anywhere from 50 to 4000 samples per second, the Gecko truly covers a broad band of frequencies from the longest period 360-second seismometer to geophones, microphones, and accelerometers with up to 1.6kHz frequency response.

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, Tremor, and Prism) – providing a solution for almost every application.

Data Sheet: Gecko seismographs and accelerographs

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 has 4 channels, perfect for a triaxial geophone plus microphone for vibration and blast compliance monitoring. Continuous data is can also be telemetered to a remote computer via cellular modem or Ethernet/WiFi adaptor. Using around 1W of power (with passive sensors) means you can record for over a month using a car battery, or indefinitely with a small solar panel and battery.

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.
