Kelunji Gecko Broadband Seismograph

The Kelunji Gecko seismograph is our 7th generation earthquake recorder, designed to be the easiest to use broadband seismographs on the market. With data captured at anywhere from 40 to 4000 samples per second, the Gecko truly covers a broad band of frequencies from the longest period 360-second seismometer to geophones and accelerometers with up to 1.6kHz frequency response.

The Gecko comes in two chassis designs: the “Compact“, a small exclosure with an iPhone-sized footprint; and the “Rugged“, which places the electronics in a waterproof chassis with a CD-sized footprint, bringing beautiful style to the Gecko’s efficient substance. Models built on the Rugged chassis with integrated sensors include two Strong Motion Accelerographs (SMA and SMA-HR), a 1Hz short period seismograph (Helix) and a 40-second or 120ssecond broadband seismograph (Prism). The Gecko Blast variant (identical in size to the SMA) brings 4.5Hz geophones into the Rugged recorder to eliminate external sensors and cabling, make blast monitoring installation super simple: lock it down, turn it on, and walk away.

Data Sheet: Gecko seismographs and accelerographs


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. From June 2018, the Gecko now has the option of 4 channels, perfect for a microphone to enhance vibration and blast compliance monitoring. Continuous data is can also be telemetered to a remote computer via wireless modem or over Ethernet. Using under 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 amplitudes that can be recorded – the ratio of the largest to the smallest recordable signal is a factor of almost 8 million to 1.
