The ATOM introduces a new style of seismograph to the Geometrics Inc range. As a stand-a-lone seismograph each Acquisition Unit (AU) is a complete recording system providing total flexibility over the number of data acquisition channels. Containing an internal battery, high accuracy GPS clock and 4 GB memory the ATOM can be deployed for up to 70 hours of continual data acquisition before recharge. For longer monitoring projects the addition of a small 5V solar panel permits data acquisition to be extended to up to 23 days with the 4GB standard internal memory; or 186 days with the optional 32GB extended memory.

No compromises have been made in terms of the performance of the system; offering up to 0.25ms sample rate the bandwidth of the system is 1.5kHz to 1650kHz with 128dB 24bit dynamic range.

Operating the instrument couldn’t be easier. Users turn the boxes on by shaking them. The box will automatically begin recording as soon as it achieves GPS lock. LEDs inform the operator of the battery status, network state, GPS time lock and geophone connection. Data is retrievable via WiFi and a laptop.

When combined with the semi-automatous SeisImager Passive Wave processing software the system is ideally suited for obtaining shear wave velocity measurements to depth up to 1km.

Compatible with any standard geophone the ATOM offers flexibility where many other similar systems don’t. A version of the ATOM with 3 measurement channels will soon hit the market; changing the face of how shallow 3 component data acquisition for geological engineering is conducted.

Geomatrix have added a IPG800 downhole seismic source to the rental pool to support customers undertaking shallow cross hole seismic investigations. The IGP800 is a lightweight portable downhole source designed to operate the BIS-SH at up to depths of 60m. The BIS-SH is a horizontal source for S-wave generation, and also provides good P-wave generation. The addtion of the IPG800 allows supports our existing IPG5000 with 100m P-wave (sparker) and S-wave sources.

Capable of being powered from a 24V DC supply the IPG800 is easy to use and more portable than other borehole S-wave sources.

The FINDIT project looks towards developing new geophysical methods which can be used to guide the maintenance and development workflows of subsurface infrastructure.

FINDIT: Not just mapping – measuring

The project combines the expertise from the University Birmingham, RSK, Geomatrix Earth Science and BT to identify methods for measuring common problems with underground asset; these include blockages, congestion and damage.

The Syscal monitoring Unit is an automated system designed to allow the operator to remotely manage the recharging of the Syscal Pro transmitter and receiver batteries during a monitoring survey.

The SMU connects the Rx and Tx batteries to an alternative source of power (solar panel, wind turbine, isolated charger, ethanol fuel cell) when the Syscal is not acquiring. During the acquisition, the external power supply is remotley disconnected from the Tx and Rx batteries to avoid any leak of current that would perturbate the measurements.

The WiConnect device improves the User Interface of the Syscal and Elrec Resistivity and IP meters from Iris Instruments.

WiConnect connects directly to the Com Port interface on the top of the instrument allowing the operator to configure the instrument and monitor measurements in real-time via a simple web browser, on any device.

To accompany the WiConnect IRIS Instruments have released new versions of Prosys II, Electre Pro, Fieldview and Comsys Pro with wifi connectivity tools.
