GüVü Bluetooth App

Displays instrument State-of-Health (SOH), waveforms, orientation, temperature and humidity data.

120 s - 100 Hz

With a remotely adjustable long-period corner of 1 s, 10 s and 120 s.

Ultra-low-power mode < 300 mW

Ideal for remote sites powered by battery or solar.

± 90° tilt range

No other seismometer is easier to install.

Wi-Fi and PoE

For plug-and-play deployment.

Multi-touch sensitive LCD screen

Optional 2.4 inch, full colour LCD display showing waveforms, instrument settings and State-of-Health (SOH), network configurations and a virtual instrument level.

For added confidence

Our GüVü Bluetooth App, displays waveforms, orientation, temperature and humidity data, plus you can alter sample rates without disturbing the instrument.



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 1 and 10 second modes adjust the high-pass frequency corners pre- or post-deployment to significantly reduce the settling time of the sensor.

Instrument and data management made simple

Our Discovery software 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.

Designed to withstand the harshest of environments

Encased in an environmentally sealed, hard anodised aluminum casing and available with or without a multi-touch sensitive, 2.4 inch, full colour LCD display. Certimus has an internal thermometer and a humidity sensor to alert you to any moisture ingress.

Field deployments made easy

For direct burial installations, data can be recorded to an SD card in the Surface Storage Module for easy retrieval without disturbance.

For remote sites, the Portable Power Pack provides a compact, re-chargeable battery suitable for direct connection to solar panels.

Ready to go whenever you are

The rugged Certimus back-pack will protect Certimus during field deployments with additional space for accessories and documentation.
