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.
