Gecko Compact Seismograph

The Gecko Compact is our best value recorder, with 3 channels for a triaxial sensor and a 4th channel input for an auxiliary sensor (e.g. a microphone for air pressure monitoring in blasting). With an in-build LCD and keypad, full instrument configuration can be done without the need for a laptop. Connect an optional Ethernet, WiFi, or cellular network modem to stream data to a remote server.

Several Gecko models are available with internal triaxial sensors housed inside a waterproof body – acceleration sensors (SMA and SMA-HR) and velocity sensors (Blast, Force, 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.

We have recently repackaged the Gecko with an internal 12+ hour battery & charger, an Ethernet interface (no battery backup), and 10A relay alarm contacts, all in a single wall mountable case which we call the Gecko ERI (Earthquake Recording Instrument) to which you can connect one of our triaxial velocity or acceleration sensors (some mass control features in 3rd party sensors may not be supported by this Gecko configuration).

Description

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.
