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.

A STATION IN A KIT

The Certis is compatible with our Rapid Deployment Kit.

Everything you need to deploy and power a weak and/or strong motion smart seismic station in a compact protective case.

The kit is fitted with a re-chargeable 400 Wh lithium battery module, two 20 W solar panels, a GNSS receiver, a modem and a modem aerial.

You can even team the Certis with a Fortis and a Minimus2 digitiser in the same kit.

SMALL, COMPACT AND ROBUST

Measuring just 112 mm tall and encased in an environmentally sealed stainless steel casing, Certis is very portable whilst capable of withstanding the harshest of environments.

An internal thermometer and a humidity sensor alert you to any moisture ingress.
