CERTIS
CERTIS
COMPACT, LOW-POWER, MEDIUM-MOTION SEISMOMETER
Serial output
Includes instrument serial number, response and calibration parameters
120 s - 100 Hz
With a remotely adjustable long-period corner of 1 s, 10 s, 20 s, 30 s, 45 s, 60 s, 90 s 100 s or 120 s
Ultra-low-power < 250 mW*
Ideal for remote sites powered by battery or solar.
*Power performance may vary as a result of restricted semi-conductor availability

± 90° tilt range
No other seismometer is easier to install.
Analogue output
For plug-and-play deployment.
For surface and posthole installations
Suitable for depths to 10 metres
Features

Easy installations
With an operational tilt range of ± 90°, the hole required for direct burial just got a lot smaller.
And, if you need to be up and running in the shortest timeframe, the long-period corner can be adjusted pre- or post-deployment* allowing you to match the response to the environment.
* when operated with a Minimus digitiser

Instrument and data management made simple
The ideal data acquisition partner for Certis is the Minimus which provides state-of-the-art communication capabilities including versatile data streaming and storage capabilities and industry standard triggering algorithms.
By pairing with a Minimus you also access Güralp Discovery, our sophisticated instrument and data management software platform.
Discovery gives you access to hardware State-of-Health; data viewing; data streaming and back fill capabilities; advanced data analysis tools; GNSS location; instrument response and calibration values.
